The existing Glow Intensity slider gains a true "0% = disabled" mode that bypasses the bloom pipeline. First-run defaults are chosen by a pure static GPU-capability heuristic. + +The plan preserves the existing architecture (per-monitor `MonitorRenderContext`, central `Application` coordinator, `RegistrySettingsProvider`, `ConfigDialog`/`ConfigDialogController` split, in-memory provider pattern for tests) and extends it without breaking changes. Net code shape is +1 provider trio, +5 pure helpers, +1 dialog group with disclosure, +5 settings fields. The "High" quality preset is intentionally calibrated to today's exact rendering so existing users see no visible change after upgrade. + +## Technical Context + +**Language/Version**: C++23 (`/std:c++latest`), MSVC v18 (Visual Studio 2026 Enterprise). +**Primary Dependencies**: D3D11 (existing), DXGI — **add `` to `pch.h`** for `IDXGIFactory6::EnumAdapterByGpuPreference`; Win32 (existing trackbars, dialogs; new tooltip control `WC_TOOLTIP` and owner-draw button); existing EHM (Error Handling Macros) and ComPtr. +**Storage**: Windows registry (existing key `HKCU\Software\relmer\MatrixRain`); new values `MultiMonitor` (DWORD), `GpuAdapter` (REG_SZ), `QualityPreset` (REG_SZ), `LastCustom_Passes` / `LastCustom_Resolution` / `LastCustom_Smoothness` / `LastCustom_GlowIntensity` (DWORDs), `ShowAdvancedGraphics` (DWORD). Persisted via the existing `RegistrySettingsProvider` helpers. +**Testing**: Microsoft C++ Native Unit Test Framework (``) via the existing `MatrixRainTests.vcxproj`. Run with `vstest.console.exe` at `…\Common7\IDE\Extensions\TestPlatform\vstest.console.exe`. Existing baseline: **354 tests passing on master**. +**Target Platform**: Windows 11 x64 only. Modern DXGI GPU-preference APIs (`IDXGIFactory6`) are available; legacy `NvOptimusEnablement`/`AmdPowerXpressRequestHighPerformance` exports are intentionally **not** added in v1.4 (see research.md). +**Project Type**: Desktop application (`MatrixRainCore.lib` + `MatrixRain.exe` + `MatrixRainTests.dll`). +**Performance Goals**: (1) On a >60 Hz monitor, render at ≤65 FPS, reducing GPU work by ≥50% relative to v1.3 baseline. (2) On a Surface-class integrated GPU with one Full-HD monitor, GPU utilization ≤70% of v1.3 baseline. (3) Topology change and GPU selection change take effect within 1 second. (4) On undock from a multi-monitor system, GPU utilization within 1 second drops to within 10% of "started in undocked state" baseline. +**Constraints**: Warnings-as-errors clean (`/W4 /WX /sdl`); no `/m` flag for MSBuild (PCH `C3859/C1076` transient memory failures); auto-bumped `Version.h` excluded from commits; existing settings keys/value layout must remain compatible (no migration of pre-existing values); single-monitor users see no visible change; "High" preset must be visually identical to today's default; flicker on dialog resize must be minimized (`SetWindowPos` with `SWP_NOZORDER | SWP_DRAWFRAME` + suppressing `WM_NCCALCSIZE` redraw bursts). +**Scale/Scope**: 5 user stories, 39 functional requirements, 10 success criteria. Code estimate ~2,000 new LOC (~800 core + helpers, ~500 dialog/UI, ~700 tests). One feature branch, multiple atomic commits per constitution. + +## Constitution Check + +*GATE: Must pass before Phase 0 research. Re-evaluated after Phase 1 design (re-evaluation results identical — no design choices conflict with any principle).* + +| Principle | Compliance | Notes | +|-----------|------------|-------| +| **I. TDD (non-negotiable)** | PASS | All pure helpers (`ShouldSpanAllMonitors` core, `ResolveAdapter`, `FormatAdapterLabel`, `IsDeviceLost`, `FrameLimiter`, `ShouldEngageFrameLimiter`, `PickDefaultQualityPreset`, `ApplyPresetSnap`, `DetectCustomDrift`, `LookupQualityPresetValues`, `LookupResolutionDivisor`, `LookupBlurTapCount`, `IsGlowDisabled`, `CoalesceRebuildRequest`) live in `MatrixRainCore` and are TDD'd against `MatrixRainTests`. Win32 dialog wiring, owner-draw of the info indicator, and DXGI device creation are out of TDD scope per the constitution's exemption for entry-point/UI code; they receive manual QA per the success criteria and the existing in-memory provider pattern for any logic they invoke. | +| **II. Performance-First** | PASS | Performance is the primary motivator. Frame cap, idle bloom-pipeline skip (via Glow Intensity 0), preset-driven resolution divisor, kernel-tap variants, and the elimination of the ghost-monitor render thread are all measured against the existing v1.3 baseline as success criteria SC-001/SC-004/SC-005. | +| **III. C++23 + Windows native** | PASS | No new tech stack. New code uses `std::optional`, structured bindings, `std::format`, `std::chrono::steady_clock`, `std::ranges` where idiomatic. Wide-string everywhere (`L"…"`, `wstring`/`wstring_view`). | +| **IV. Modular architecture** | PASS | New code introduces one new interface (`IAdapterProvider`) with two implementations (`WindowsAdapterProvider`, `InMemoryAdapterProvider`) and ≤14 pure free-function helpers grouped by concern (`AdapterSelection.{h,cpp}`, `FrameLimiter.{h,cpp}`, `QualityPresets.{h,cpp}`, `MultiMonitorGate.{h,cpp}`, `DeviceLost.{h,cpp}`, `RebuildCoalescer.{h,cpp}`). Dependencies flow one direction: providers/helpers ← `Application` ← `MonitorRenderContext` ← `RenderSystem`. No circular dependencies. | +| **V. Type safety + modern idioms** | PASS | `enum class QualityPreset`, `enum class ResolutionDivisor`, `enum class BlurTaps`. `std::optional` for "no GPU saved". ComPtr for COM lifetimes. `const`-correct throughout. | +| **VI. Library-first** | PASS | All logic in `MatrixRainCore.lib`. `MatrixRain.exe` gains only `ConfigDialog.cpp` UI glue (already its role today), `.rc` resource changes, and `resource.h` IDs. No business logic added to `.exe`. | +| **VII. PCH** | PASS | One new include (``) added to `pch.h` in the appropriate alphabetical group. No system headers added to other files. Test PCH continues to `#include` core PCH. | +| **VIII. Code formatting and style** | PASS | All new code follows the existing project conventions: 5 blank lines between top-level constructs, column-aligned declarations with `*`/`&` as their own column, function header comment banners (80 char), Win32 trackbar/combo pattern matching `ConfigDialog.cpp` precedent. Hungarian-prefix discipline preserved where the surrounding code uses it; modern names elsewhere. | +| **IX. Commit discipline** | PASS | Tasks.md (next phase) breaks work into atomic units, each producing a single commit after build + full test pass. Sequencing: spec/plan/research/data-model/quickstart/contracts (one commit total — this branch initialization) → then per-task commits. | + +**Verdict**: No violations.

Acceptance walkthrough + +### US1 — Runtime topology and device-loss response (P1) + +1. Connect a second monitor. Launch MatrixRain. Confirm it renders on both monitors. +2. Open Task Manager (Performance → GPU) and note the application's GPU utilization. +3. Disconnect the second monitor (physically unplug or disable in Display Settings → "Disconnect this display"). +4. Within 1 second: only the remaining monitor continues rendering; GPU utilization drops to within 10% of "starting MatrixRain fresh with one monitor" (US1 SC-001). +5. Reconnect the second monitor. Within 1 second: MatrixRain begins rendering to it without restart (US1 SC-002). +6. Optional: disable the active GPU's driver via Device Manager. MatrixRain recovers automatically; no error dialog appears. + +### US2 — Multi-monitor optional toggle (P1) + +1. Launch MatrixRain on a multi-monitor system. +2. Press Enter (or right-click → Configure) to open the configuration dialog. +3. Find the "Render on all monitors" checkbox; verify it is checked by default. +4. Uncheck it and click OK. +5. Within 1 second: secondary monitors return to their normal desktop content; primary continues showing MatrixRain. +6. Restart MatrixRain. Verify it starts on the primary only (setting persisted). +7. Open the dialog, re-check the checkbox, OK. Verify all monitors resume rendering within 1 second. + +### US3 — GPU adapter selection (P2) + +*Requires a hybrid laptop or system with multiple non-software GPUs.* + +1. Open the configuration dialog. Locate the GPU dropdown. +2. Verify each adapter is listed by its real name. The system default has `" (default)"` appended (e.g., `"NVIDIA GeForce RTX 3050 Ti (default)"`). +3. Verify software adapters (Microsoft Basic Render Driver) are NOT listed. +4. Select a non-default adapter and click OK. +5. Within 1 second: in Task Manager, MatrixRain's GPU usage switches to the selected GPU. +6. Restart MatrixRain. Verify it starts on the selected GPU. +7. To test the "adapter vanished" path: edit `HKCU\Software\relmer\MatrixRain\GpuAdapter` to a fake name (e.g., `"Acme GPU 9000"`). Restart MatrixRain. Verify it starts successfully on the default adapter without any error dialog. + +### US4 — Frame-rate cap on high-refresh monitors (P2) + +*Best validated on a system with a >60Hz monitor.* + +1. Enable debug statistics in MatrixRain (Configuration → Show debug statistics). +2. On a >60Hz monitor: launch MatrixRain. Read the on-screen FPS. Expected: approximately 60. +3. On a 60Hz monitor: launch MatrixRain. Read the on-screen FPS. Expected: approximately 60 (existing behavior). +4. Mixed-refresh multi-monitor system: confirm each monitor independently shows ~60 FPS. +5. Optional: compare GPU utilization on the high-refresh monitor before and after this feature. Expected: ≥50% reduction (US4 SC-004). + +### US5 — Graphics quality presets and advanced controls (P3) + +1. Open the configuration dialog. Locate the "Quality" dropdown. +2. Verify entries: `Low`, `Medium`, `High`, `Custom`. +3. Switch through `Low` → `Medium` → `High`. Verify visible changes to glow appearance. +4. Locate the "Show advanced graphics settings" checkbox. Check it; the dialog grows to reveal three sliders (Passes / Resolution / Smoothness) and four `ⓘ` indicators next to the quality controls. +5. Move any advanced slider; verify the Quality dropdown switches to `Custom` automatically. +6. Switch the Quality back to `High`; verify all advanced sliders snap to High's values. +7. Switch back to `Custom`; verify the previously-customized values are restored. +8. Drag the Glow Intensity slider to 0%; verify the value label reads `"0% (glow disabled)"` and the glow effect is fully gone (not just darker). +9. Hover the mouse over each `ⓘ`; verify a tooltip appears containing descriptive text ending in one of: + - `"Significant GPU performance impact."` + - `"Moderate GPU performance impact."` + - `"Small GPU performance impact."` +10. Tab to each `ⓘ` (verify each is keyboard-focusable). Press Space. Verify the same tooltip appears for the focused indicator. +11. Uncheck "Show advanced graphics settings". Verify the dialog shrinks and the advanced controls are hidden; the OK/Cancel/Reset buttons remain accessible. +12. Restart MatrixRain.

All technical unknowns were resolved during the pre-spec planning discussion with the user; this document consolidates the chosen approaches, the rationale, and the alternatives considered, so subsequent phases can proceed without further investigation. + +--- + +## R-001: Multi-monitor enabled/disabled — runtime apply + +**Decision**: Toggling the setting POSTs `WM_APP_REBUILD_CONTEXTS` to the application's main window; the existing `RebuildContextsForCurrentMode` flow (`Application.cpp:883-940`) tears down all `MonitorRenderContext` threads, re-enumerates monitors, recomputes the layout, and starts the new set. Settings-driven gate is via a pure `ShouldSpanAllMonitors(bool multimonEnabled, DisplayMode displayMode, ScreenSaverMode saverMode)` helper used by `Application::ShouldSpanAllMonitors()` (`Application.cpp:374-388`). + +**Rationale**: This is the same teardown/rebuild path already used today for Alt+Enter (mode toggle), so we get atomicity, lock ordering, and overlay/dialog handling for free. The pure gate is unit-testable in isolation, eliminating logic from the Win32 layer. + +**Alternatives considered**: Apply at next launch only (rejected per user direction — feels broken). Selectively start/stop per-monitor contexts without a full rebuild (rejected — added complexity for a setting that changes infrequently and is already cheap to rebuild). + +--- + +## R-002: Runtime monitor add/remove detection + +**Decision**: Add a `case WM_DISPLAYCHANGE:` handler to `Application::HandleMessage` (`Application.cpp:1081…`). On receipt, set an `std::atomic_flag m_rebuildPending` and POST a single `WM_APP_REBUILD_CONTEXTS`. The `WM_APP_REBUILD_CONTEXTS` handler clears the flag and runs `RebuildContextsForCurrentMode`. This coalesces the burst of `WM_DISPLAYCHANGE` messages the system broadcasts to every top-level window in a multi-window app. + +**Rationale**: `WM_DISPLAYCHANGE` is the standard, kernel-broadcast notification. Windows delivers it to every top-level window (which on multimon = once per `MonitorRenderContext` hwnd). Without coalescing we would trigger N rebuilds for one topology change. The atomic flag is the simplest viable coalescing strategy and is pure-testable as a `CoalesceRebuildRequest(flag)` helper. + +**Alternatives considered**: `WM_DEVICECHANGE` filter for monitor devices (rejected — fires for many unrelated device classes, more complex filter, no advantage over `WM_DISPLAYCHANGE`). Polling `EnumDisplayMonitors` on a timer (rejected — wasteful and laggy). `IDXGIFactory::RegisterStereoStatusWindow` and friends (irrelevant API). + +--- + +## R-003: Device-loss detection and recovery + +**Decision**: Capture the HRESULT returned from `m_swapChain->Present(1, 0)` in `RenderSystem::Present` (`RenderSystem.cpp:1753-1758`). Pure helper `bool IsDeviceLost(HRESULT)` returns true for `DXGI_ERROR_DEVICE_REMOVED`, `DXGI_ERROR_DEVICE_RESET`, `DXGI_ERROR_DEVICE_HUNG`, `DXGI_ERROR_DRIVER_INTERNAL_ERROR`, and `D3DDDIERR_DEVICEREMOVED`. On true, the `MonitorRenderContext` render thread exits its loop and POSTs `WM_APP_REBUILD_CONTEXTS` to its HWND. The main-thread rebuild re-resolves the chosen adapter via `ResolveAdapter` (which falls back to default if the prior selection vanished) and reinitializes. + +**Rationale**: `Present` is the canonical detection point for D3D11. Classifying via a pure helper lets us unit-test the HRESULT mapping without a real device. The render-thread-posts-to-UI-thread pattern reuses the existing rebuild barrier, ensuring lock-correctness. + +**Alternatives considered**: Calling `GetDeviceRemovedReason` only on `DXGI_ERROR_DEVICE_REMOVED` (kept as best-effort logging within the same path). Polling `IDXGIDevice::GetCreationFlags` or similar (no useful liveness signal). Catching the error at `D3D11CreateDevice` rebuild time only (insufficient — first symptom is at Present). + +--- + +## R-004: GPU adapter enumeration and persistence + +**Decision**: +- **Enumeration**: New `IAdapterProvider` interface with `WindowsAdapterProvider` (uses `CreateDXGIFactory1` → `IDXGIFactory1::EnumAdapters1` for the list; uses `CreateDXGIFactory2` → `IDXGIFactory6::EnumAdapterByGpuPreference(0, DXGI_GPU_PREFERENCE_UNSPECIFIED, …)` to identify the system default; filters out adapters with `DXGI_ADAPTER_FLAG_SOFTWARE`). +- **Persistence**: Adapter is stored by `DXGI_ADAPTER_DESC1::Description` (REG_SZ at value name `GpuAdapter` under `HKCU\Software\relmer\MatrixRain`). Empty string = "use system default". +- **Resolution**: Pure helper `ResolveAdapter(const vector& adapters, const wstring& savedDescription) -> std::optional`. Returns the matching adapter's LUID, or `nullopt` if the saved description is empty or not found (caller then calls `D3D11CreateDevice(nullptr, D3D_DRIVER_TYPE_HARDWARE, …)`). +- **Device creation**: `RenderSystem::Initialize` (`RenderSystem.cpp:146-180`) gains an optional adapter LUID parameter. If supplied, `IDXGIFactory4::EnumAdapterByLuid` looks up the adapter and `D3D11CreateDevice(adapter, D3D_DRIVER_TYPE_UNKNOWN, …)` creates the device on it. If absent, the existing `nullptr` + `D3D_DRIVER_TYPE_HARDWARE` path is preserved unchanged. + +**Rationale**: Description-string persistence trades a tiny risk of driver-update renames for the considerable benefit of human-readable, reboot-stable identification. LUID is not guaranteed stable across reboots; enumeration index is not stable across hardware changes. The mandatory `D3D_DRIVER_TYPE_UNKNOWN` paired with a non-null adapter is a documented D3D11 requirement. Excluding software adapters matches the user's intent ("hybrid laptops, pick integrated vs discrete"). + +**Alternatives considered**: LUID-based persistence (rejected — not stable). Enumeration index (rejected — fragile). Synthetic "Default" + "High performance" preference entries instead of real adapter names (rejected per user — show real names). Legacy `extern "C" __declspec(dllexport) DWORD NvOptimusEnablement = 1;` and `int AmdPowerXpressRequestHighPerformance = 1;` exports (rejected for v1.4 — they are static, evaluated at process load, and would force the discrete GPU always, defeating the integrated-for-power case; on Windows 10 1803+ the DXGI-based path is sufficient). + +--- + +## R-005: Hybrid-laptop discrete-GPU routing + +**Decision**: Rely entirely on `IDXGIFactory6::EnumAdapterByGpuPreference` for advertising the high-performance adapter and on `D3D11CreateDevice(adapter, D3D_DRIVER_TYPE_UNKNOWN, …)` for actually creating the device on the user's chosen physical GPU. Document the cross-adapter present-time copy (DWM runs on the integrated GPU) as expected behavior. + +**Rationale**: On Windows 10 1803+ with current drivers the DXGI path correctly routes the process to the chosen physical GPU on NVIDIA Optimus, AMD PowerXpress, and Surface-class hybrid systems. Adding the legacy magic-export symbols would *force* discrete always (they are evaluated at process-load time before any user setting is read), which is exactly the wrong behavior for a "let the user pick" feature. + +**Alternatives considered**: Adding the legacy magic exports as a belt-and-suspenders fallback (deferred — revisit only if real-world testing on a target hybrid configuration shows the OS-level APIs are insufficient). Modifying the per-app OS GPU preference at `HKCU\…\DirectX\UserGpuPreferences` (rejected — too invasive; that's a user-controlled OS setting). + +--- + +## R-006: Frame-rate cap on high-refresh monitors + +**Decision**: Pure `FrameLimiter` class wrapping a `std::chrono::steady_clock` last-frame timestamp. API: `void TargetFps(unsigned)` to configure, `void WaitForNextFrame()` to block (sleep) until next frame slot. A pure free function `bool ShouldEngageFrameLimiter(unsigned monitorRefreshHz)` returns true iff `monitorRefreshHz > 60`. `MonitorRenderContext::Initialize` accepts the monitor's refresh rate and, when the engage predicate is true, calls `WaitForNextFrame` at the top of each render-loop iteration before the existing `Present(1, 0)`; otherwise the limiter is bypassed entirely and the loop is unchanged. + +**Rationale**: `steady_clock` is monotonic and the natural fit. Per-monitor refresh is already available via `DEVMODE::dmDisplayFrequency` or the existing monitor-enumeration data. Gating on `> 60Hz` keeps the 60Hz case zero-overhead. The pure helpers are trivially unit-tested (elapsed → sleep math; engage truth table). + +**Alternatives considered**: `QueryPerformanceCounter` (no benefit over `steady_clock` for ~60Hz timing). DXGI `WaitableObject` swap chains (more complex; would force a separate code path for the high-refresh case; benefit not justified). Global frame cap across all monitors regardless of refresh (rejected per user direction). + +--- + +## R-007: Bloom-pipeline parametrization + +**Decision**: Replace the hardcoded values in `RenderSystem::ApplyBloom` (`RenderSystem.cpp:1328-1395`) with run-time parameters: +- **Blur iterations**: was hardcoded `for (int pass = 0; pass < 3; ++pass)` at `:1372`; becomes `m_blurPasses` (1..4). +- **Bloom buffer resolution**: was hardcoded `width / 2` / `height / 2` (`:1175-1176`, viewport `:1337`); becomes `width / m_bloomResolutionDivisor` (divisor ∈ {1, 2, 4, 8} mapping Full/Half/Quarter/Eighth). +- **Blur kernel taps**: select one of three precompiled blur shader variants (5-tap, 9-tap, 13-tap) at bind time. Variants are compiled at startup alongside the existing extract/composite shaders. +- **Glow on/off**: when Glow Intensity == 0, the entire bloom pipeline is bypassed (the existing direct-to-backbuffer fallback at `:1731` is taken). + +**Rationale**: Discrete shader variants for kernel taps avoid the dynamic-loop cost of a uniform-driven blur kernel and let HLSL fully unroll each variant. The integer divisor for resolution preserves the existing texture-recreation path with no special-case math. Bypassing the pipeline at intensity == 0 gives the true power savings the user expects from "off" (no extract pass, no blur passes, no composite pass). + +**Alternatives considered**: One blur shader with a `loopCount` uniform (rejected — dynamic loops are slow; lost optimization headroom). Skipping individual passes by conditional `RenderFullscreenPass` calls in the loop (less clean than parametrizing the loop bound). + +--- + +## R-008: Quality preset spectrum and custom-snap behavior + +**Decision**: +- **Presets**: `enum class QualityPreset { Low, Medium, High, Custom }`. +- **Preset → knob map** (in `QualityPresets.cpp`, pure lookup table): + + | Preset | GlowIntensity | Passes | Resolution | Smoothness | + |--------|---------------|--------|------------|------------| + | Low | 75 | 1 | Quarter | Low (5) | + | Medium | 100 | 2 | Half | Med (9) | + | High | 100 | 3 | Half | High (13) | + +- **High == today's exact values** — by design, so existing users see no change after upgrade. +- **First-run heuristic**: `PickDefaultQualityPreset(AdapterClass, dedicatedVramMB, totalPixelCount)`: + - Any discrete adapter → `High`. + - Integrated only, totalPixelCount ≤ ~16M → `Medium`. + - Integrated only, totalPixelCount > ~16M → `Low`. +- **Custom-snap behavior** (pure helpers `ApplyPresetSnap`, `DetectCustomDrift`): + - Preset → named preset: all advanced controls snap to that preset's row. + - Any advanced control change: preset auto-flips to `Custom`; current values become the in-memory `LastCustom`. + - Preset → `Custom`: if a saved `LastCustom` exists in the registry, restore it; else leave the advanced controls at their current values (whatever the previous preset's values were until the user touches one). +- **Persistence**: `QualityPreset` (REG_SZ "Low"/"Medium"/"High"/"Custom"). `LastCustom_Passes` / `LastCustom_Resolution` / `LastCustom_Smoothness` / `LastCustom_GlowIntensity` (DWORDs) — written whenever `LastCustom` is updated, even if the active preset is named (so the user gets their last custom back when they later switch to Custom). + +**Rationale**: Three named presets cover the meaningful design points and avoid the redundancy of the originally proposed Battery (already reachable via Glow Intensity 0) and Ultra (gratuitous for a screensaver). The first-run heuristic is intentionally static and run only when no preset is saved (no runtime adaptive downshift), per the user's explicit preference. The custom-snap behavior makes preset switching predictable and never silently loses user work. + +**Alternatives considered**: Five-preset spectrum (rejected as redundant — see above). Three presets with auto-saved per-preset "last custom" overrides (over-engineered). Continuous quality slider 0..100 (rejected — there's no natural continuum across the three independent knobs). + +--- + +## R-009: Information tip ("ⓘ") control + +**Decision**: Each information tip is an owner-drawn `BS_OWNERDRAW | WS_TABSTOP` push button (~12×12 dialog units) drawn via `WM_DRAWITEM` as a 1-pixel circle outline with a lowercase "i" centered inside. A single shared `WC_TOOLTIP` window (created in `OnInitDialog`) hosts the actual tooltip text. Each info button is registered as a tool with `TTF_IDISHWND | TTF_SUBCLASS` for hover behavior. For keyboard activation, each info button's `BN_CLICKED` handler positions the tooltip below/right of the button and calls `TTM_TRACKACTIVATE` on a parallel `TTF_TRACK` registration; the tooltip dismisses on kill-focus, ESC, or a 5-second timer. Per-button text is supplied via `TTN_GETDISPINFO`, keyed by control ID. + +**Rationale**: Owner-draw guarantees a crisp circle + "i" at any DPI without depending on a specific font glyph being installed. Real `BUTTON` controls are naturally focusable (Tab) and fire `BN_CLICKED` on Space/Enter, so keyboard accessibility comes for free. The single shared tooltip + per-tool text is the standard Win32 idiom and minimizes window count. + +**Alternatives considered**: Static control with the Unicode "info" code point (U+2139 ℹ or U+24D8 ⓘ) (rejected — font-availability fragile, not focusable). Segoe MDL2 Assets "Info" glyph U+E946 in a label (rejected — font/DPI fragility, not focusable). Custom small dialog modal popup instead of a tooltip (over-engineered, breaks Win32 conventions). + +--- + +## R-010: Configuration dialog dynamic resize + +**Decision**: Lay out the `.rc` template at the EXPANDED size (with the advanced controls visible). In `OnInitDialog`, after loading settings: +1. Record each advanced control's rect (via `GetWindowRect` + screen-to-client). +2. Compute `advancedBlockHeight` = (lowest advanced control's bottom) − (highest advanced control's top) + spacing. +3. If the user's last `ShowAdvancedGraphics` setting is off (the default), hide the advanced controls (`ShowWindow(SW_HIDE)`), shrink the dialog by `advancedBlockHeight` (`SetWindowPos`), and move the OK/Cancel/Reset row (and anything below the advanced block) up by the same amount. + +On `BN_CLICKED` of `IDC_GRAPHICS_ADVANCED_CHECK`, run the inverse transform and persist the new setting. Use DPI-aware computation by sourcing the height from the actual control rects (which already scale with the dialog's font), not from a hardcoded pixel value. + +**Rationale**: Working from the expanded layout in the `.rc` keeps the layout authority in the resource editor (and avoids fragile DPI math at runtime). Capturing the block height from actual control rects in `OnInitDialog` automatically picks up the correct DPI-scaled value. Moving the buttons (and any controls below the advanced block) by the same delta keeps the visual layout consistent in both states. + +**Alternatives considered**: Two separate dialog templates (rejected — control IDs would need to differ, doubling event-handling code). Fixed taller dialog with reserved empty space (rejected per user — leaves an empty gap that looks broken). `SetWindowRgn` to clip out the advanced area (visual artifacts, doesn't reflow buttons). + +--- + +## R-011: Tick-mark conventions for trackbars + +**Decision**: Apply the following rules to all percentage trackbars in the dialog (recorded as a contract in `contracts/tick-mark-conventions.md`): +- **Discrete sliders** (Passes, Resolution, Smoothness): `TBS_AUTOTICKS` plus labeled ticks under each tick mark (achieved with `LTEXT` statics aligned at the tick screen-x positions in the dialog template). +- **Percentage sliders, common rule**: tick frequency chosen so a tick falls at the midpoint of the range and ~21 ticks total are produced. Concrete per-slider settings: + + | Slider | Range | Mid | `TBM_SETTICFREQ` | Ticks | Notes | + |-----------------|---------|-----|------------------|-------|------------------------------------| + | Density | 0..100 | 50 | 5 | 21 | Exact midpoint tick | + | Speed | 1..100 | — | 5 | 21 | freq=5 → 20 ticks 1..96; one extra explicit tick at 100 via `TBM_SETTIC` | + | Glow Intensity | 0..200 | 100 | 10 | 21 | Exact midpoint tick | + | Glow Size | 50..200 | 125 | 5 | 31 | freq=10 would miss 125; freq=5 keeps midpoint, accept denser tick count | + +- All percentage sliders are unlabeled and non-snapping. + +**Rationale**: A midpoint tick is a strong visual anchor and the user explicitly requested it. The 21-tick target keeps visual density consistent; Glow Size is the outlier because its range (150) doesn't divide cleanly. Speed needs one explicit tick because its range (1..100) doesn't permit an integer midpoint and `TBM_SETTICFREQ` would otherwise stop at 96. + +**Alternatives considered**: Widening Glow Size range to 50..250 to fit the 21-tick rule (rejected — invents range purely to satisfy tick math; alters user-visible setting space for no functional reason). freq=10 on Glow Size yielding 16 ticks but no midpoint tick (rejected per user requirement). Per-slider TBM_SETTIC arrays everywhere (over-engineered for sliders that already work with `TBS_AUTOTICKS`). + +--- + +## R-012: Test strategy + +**Decision**: Extend the existing pure-helper + InMemoryProvider test pattern (already used by `MonitorEnumeratorTests`, `MonitorLayoutTests`, `IRenderSystemTests`, `RenderThreadInputsTests`). New unit tests target the pure helpers introduced by this feature; Win32 UI and DXGI device-creation paths are covered by manual QA per the success criteria, since they are out of TDD scope per the constitution's exemption. + +**Rationale**: Reuses the proven test architecture (354 tests passing on master). Every meaningful behavior introduced by this feature is decomposable into a pure function that is exhaustively testable without a real device, monitor, or window. The Win32 wiring layer is thin glue; manual QA on real hybrid hardware is the highest-value remaining verification. + +**Alternatives considered**: WTL/CppWinUI integration tests for the dialog (excessive scope). Hooking `D3D11CreateDevice` for adapter-routing tests (fragile, low ROI). + +--- + +## R-013: Build/test environment quirks (carried over from prior work) + +**Decision**: No new tooling. Documented constraints: +- Build: `MSBuild.exe /p:Configuration=Debug /p:Platform=x64 MatrixRain.sln` (no `/m` — transient PCH `C3859`/`C1076` memory failures). +- Test: `vstest.console.exe MatrixRainTests.dll /Platform:x64 /InIsolation`. +- `Version.h` is auto-bumped pre-build; exclude from commits. +- Commit messages: PowerShell has no heredoc — write to a temp file, `git commit -F`, remove. Conventional Commits + `Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>` trailer. +- `/W4 /WX /sdl`: C4189 (unused variable) and C4100 (unreferenced parameter) break builds; use `UNREFERENCED_PARAMETER` or remove the binding. + +**Rationale**: Carried forward from the prior multimon work that ships on this base; no change. + +--- + +## Open items + +None.

They undock the laptop, disconnecting the external monitor. MatrixRain continues running on the remaining laptop screen and immediately stops consuming GPU work for the disconnected monitor. When they redock, the external monitor begins displaying MatrixRain again without restarting the application. + +**Why this priority**: This is a correctness defect today. After an undock, MatrixRain continues rendering at ~90% GPU into a non-existent monitor; on this hardware it can never recover until the user restarts the application. Fixing this is a blocking quality issue for hybrid-laptop users, who are also the population most affected by all other items in this feature. + +**Independent Test**: With MatrixRain running on a multi-monitor setup, physically disconnect one monitor (or disable it in Display Settings) and verify that within a few seconds GPU utilization for MatrixRain drops to a level consistent with rendering only to the remaining monitors. Reconnect the monitor and verify MatrixRain resumes rendering to it without manual intervention. + +**Acceptance Scenarios**: + +1. **Given** MatrixRain is running spanning two monitors at high GPU load, **When** the user disconnects one monitor, **Then** within 1 second only the remaining monitor continues to be rendered and GPU utilization drops to a level comparable to having started in the new topology. +2. **Given** MatrixRain is running on a single monitor after a disconnect, **When** the user reconnects an additional monitor, **Then** MatrixRain begins rendering to it within 1 second without requiring restart. +3. **Given** MatrixRain is rendering on a specific GPU and that GPU's driver is reset or it becomes temporarily unavailable, **When** the device-loss event occurs, **Then** MatrixRain recovers automatically and resumes rendering without user intervention or visible error dialogs. + +--- + +### User Story 2 - Choose whether MatrixRain spans all monitors (Priority: P1) + +A multi-monitor user opens MatrixRain's configuration dialog and toggles off the "render on all monitors" option because they only want the screensaver on their primary display. The change takes effect immediately on the running instance and persists across restarts. + +**Why this priority**: Multi-monitor rendering is currently always-on. Some users find this distracting (gaming/working secondary monitor, ambient lighting on a TV in the same room) or simply want lower GPU cost. Today they have no opt-out. Making it a setting (default on) is small but unblocks a real user choice. + +**Independent Test**: Open the configuration dialog on a multi-monitor system, locate the "render on all monitors" control, toggle it off, dismiss the dialog. Verify MatrixRain immediately stops rendering on non-primary monitors. Reopen the dialog and confirm the setting persisted; toggle it back on and verify all monitors resume rendering. + +**Acceptance Scenarios**: + +1. **Given** MatrixRain is running on multiple monitors with the multi-monitor setting on (default), **When** the user opens the configuration dialog and turns the setting off, **Then** within 1 second only the primary monitor continues rendering and the secondary monitors return to their normal desktop content. +2. **Given** MatrixRain was last configured with the multi-monitor setting off, **When** the application is launched, **Then** it renders only on the primary monitor. +3. **Given** a single-monitor system, **When** the user opens the configuration dialog, **Then** the multi-monitor control is present but has no effect on behavior (always renders on the one available monitor). + +--- + +### User Story 3 - Pick which GPU MatrixRain uses on hybrid laptops (Priority: P2) + +A user on a Surface Book 3, Surface Laptop Studio 2, or NVIDIA Optimus / AMD PowerXpress laptop opens MatrixRain's configuration dialog. They see a list of the GPUs available on their machine by their real names (e.g., "Intel Iris Xe Graphics", "NVIDIA GeForce RTX 3050 Ti"), with the system default annotated. They select the integrated GPU to extend battery life. MatrixRain begins running on that GPU and the change persists across restarts. + +**Why this priority**: On hybrid laptops, MatrixRain currently always runs on whichever GPU the operating system chose. There is no way for the user to prefer the lower-power integrated GPU when on battery, or the higher-performance discrete GPU when plugged in. The previous priority items (US1, US2) have higher urgency: US1 fixes a defect that affects this same hardware, US2 is the smallest power lever. With those addressed, this becomes the next-most-impactful user control. + +**Independent Test**: On a hybrid-laptop system with two or more rendering-capable adapters, open the configuration dialog and verify the GPU list shows the real adapter names with "(default)" appended to the system default. Select a non-default adapter, dismiss the dialog. Verify (via Task Manager's GPU view) that MatrixRain switches to using the selected GPU. Restart MatrixRain and verify it starts on the selected GPU. Choose a GPU that doesn't exist (by editing the saved setting to a fake name), restart, and verify MatrixRain falls back to the default adapter without error. + +**Acceptance Scenarios**: + +1. **Given** a system with multiple non-software GPU adapters, **When** the user opens the configuration dialog, **Then** the GPU selection control lists each adapter by its real name and the system default adapter is annotated with "(default)". +2. **Given** software/basic-render adapters exist on the system, **When** the user views the GPU selection list, **Then** those adapters are not included in the list. +3. **Given** the user has selected a specific GPU, **When** the dialog is dismissed, **Then** MatrixRain begins rendering on that GPU within 1 second on the running instance and continues to do so on subsequent launches. +4. **Given** a previously selected GPU is no longer present on the system at launch (removed, disabled, or driver uninstalled), **When** MatrixRain starts, **Then** it falls back to the system default adapter and starts successfully without showing an error dialog. + +--- + +### User Story 4 - Cap frame rate on high-refresh monitors (Priority: P2) + +A user with a 144Hz laptop display starts MatrixRain. Rather than rendering 144 frames per second per monitor (wasteful for a screensaver), MatrixRain limits itself to 60 frames per second on that monitor, substantially reducing GPU work. A user on a 60Hz monitor sees no change from prior behavior. + +**Why this priority**: High-refresh displays are common on modern laptops, and rendering a screensaver at 144 FPS is gratuitously expensive — every frame pays the full rendering and bloom cost. A simple per-monitor cap at 60 FPS for refresh > 60Hz is the largest guaranteed GPU saving available with no visible quality impact for this content. Lower priority than US1/US2 only because it is invisible to users (no UI to surface it) and its impact is felt as cooler hardware rather than as a feature. + +**Independent Test**: On a system with a >60Hz monitor, run MatrixRain with debug statistics enabled and verify the FPS counter on that monitor reports approximately 60. On a system with a 60Hz monitor, verify the FPS counter reports approximately 60 (the existing behavior). Compare GPU utilization on the high-refresh case before and after the change to confirm a substantial reduction. + +**Acceptance Scenarios**: + +1. **Given** a monitor whose native refresh rate is greater than 60Hz, **When** MatrixRain renders to that monitor, **Then** rendering is limited to approximately 60 frames per second on that monitor. +2. **Given** a monitor whose native refresh rate is 60Hz or less, **When** MatrixRain renders to that monitor, **Then** rendering continues at the monitor's native refresh rate as before, without any added overhead from the limiter. +3. **Given** a multi-monitor setup with mixed refresh rates (e.g., 60Hz primary and 144Hz secondary), **When** MatrixRain renders to both, **Then** the 60Hz monitor runs at 60 FPS and the 144Hz monitor also runs at approximately 60 FPS, each evaluated independently. + +--- + +### User Story 5 - Tune graphics quality with presets and an advanced disclosure (Priority: P3) + +A user opens MatrixRain's configuration dialog and sees a "Quality" preset selector offering Low, Medium, and High. They pick Low for battery savings or High for the richest look. A more advanced user enables an "advanced graphics settings" toggle that reveals individual controls for the number of glow passes, the resolution of the glow buffer, and the smoothness of the glow blur. As they adjust any individual control, the preset selector automatically switches to "Custom" and remembers those values for next time they pick Custom. Each quality control has an "ⓘ" indicator next to it; hovering the mouse over it or tabbing to it and pressing Space/Enter shows a short description of the control and its GPU performance impact (Significant / Moderate / Small). + +**Why this priority**: This is the most powerful efficiency lever (resolution divisor alone can be ~4x cheaper) but it is also the largest UI surface in this feature. It is lower priority than US1-US4 because: US1 fixes a defect; US2/US3 are simpler controls that unlock immediate user choice; US4 captures the largest fixed win without any UI work. US5 is the long-tail quality/perf control surface that benefits power-conscious users who want to dial in their own tradeoff. + +**Independent Test**: Open the configuration dialog, locate the Quality preset selector, verify Low/Medium/High options are present. Switch through them and verify visible changes to glow appearance. Enable the advanced toggle and verify three additional controls appear (Passes, Resolution, Smoothness). Move any one of them and verify the preset selector switches to Custom. Switch the preset back to High; verify all advanced controls snap to the High preset's values.

unchecking the toggle reverses this. +4. **Given** any named preset is selected, **When** the user moves an advanced control, **Then** the preset selector automatically switches to "Custom" and the current advanced control values are remembered as the "last custom" set. +5. **Given** a named preset is selected, **When** the user selects a different named preset, **Then** all advanced controls snap to that preset's defined values. +6. **Given** the user has previously used Custom and saved a custom set of values, **When** the user selects "Custom" from the preset selector after having moved through named presets, **Then** the advanced controls restore to the saved custom values. +7. **Given** the user has never used Custom in this dialog session and there is no saved custom set, **When** the user selects "Custom" from the preset selector, **Then** the advanced controls remain at their current values. +8. **Given** the existing Glow Intensity slider, **When** the user moves it to 0%, **Then** the glow effect is fully disabled (not merely darker) and the slider's value indicator reads "0% (glow disabled)". +9. **Given** any quality-related control with an "ⓘ" indicator, **When** the user hovers the mouse over the indicator OR tabs to it with the keyboard and presses Space or Enter, **Then** a tooltip appears containing descriptive text and ending with exactly one of "Significant GPU performance impact.", "Moderate GPU performance impact.", or "Small GPU performance impact.". +10. **Given** a fresh installation with no saved quality preset, **When** the user launches MatrixRain on a system with a discrete GPU, **Then** the High preset is applied; on a system with only an integrated GPU and a modest pixel load, the Medium preset is applied; on a system with an integrated GPU driving multiple high-resolution monitors, the Low preset is applied. + +--- + +### Edge Cases + +- A user toggles the "render on all monitors" setting off while MatrixRain is currently spanning multiple monitors: the secondary monitor windows must be cleanly removed within 1 second and not leave stale or frozen content on those displays. +- A monitor is added or removed while MatrixRain is running in screensaver mode (`/s`): MatrixRain must adapt and keep running rather than exiting, the same as in normal display mode. +- A user toggles the "render on all monitors" setting off and then immediately back on: MatrixRain must end in the fully-spanning state without leaving any monitor stuck in an in-between state. +- The user's previously selected GPU has been removed, disabled, or replaced between MatrixRain runs: MatrixRain must start successfully on the default adapter without an error dialog and without losing the user's other preferences. +- The user's previously selected GPU is removed *while MatrixRain is running*: MatrixRain must detect the loss and continue running on the default adapter. +- A laptop is suspended and resumed while MatrixRain is running: MatrixRain must recover gracefully (the GPU and monitors may have effectively been "removed and re-added" from MatrixRain's perspective). +- The system reports a monitor whose native refresh rate cannot be determined: MatrixRain must fall back to standard vertical-sync behavior rather than refusing to render or capping incorrectly. +- The user selects "Custom" before ever having moved an advanced control: the advanced controls must stay at their current values (whatever named preset they reflect), and from that point any subsequent adjustment becomes the new "last custom". +- A configuration dialog is open while a monitor is removed: the dialog must remain functional and dismissible; new MatrixRain behavior takes effect after dialog dismissal. +- The user cancels (rather than OKs) the configuration dialog after having adjusted multiple controls in advanced mode: all live previews are reverted and persisted settings are unchanged. + +## Requirements *(mandatory)* + +### Functional Requirements + +#### Multi-monitor user control + +- **FR-001**: System MUST provide a user-visible setting in the configuration dialog to enable or disable multi-monitor spanning. +- **FR-002**: Multi-monitor spanning MUST default to enabled for new installations and for existing users who have never seen this setting. +- **FR-003**: Toggling the multi-monitor setting MUST take effect on the running application within 1 second, without restart. +- **FR-004**: System MUST persist the multi-monitor setting across application restarts. + +#### Runtime topology and device-loss response + +- **FR-005**: System MUST detect monitor connection and disconnection events while running. +- **FR-006**: When monitors are added or removed, system MUST adapt within 1 second so that rendering resources for absent monitors are released and rendering resources for newly-present monitors are created. This MUST happen in both normal display mode and screensaver mode (`/s`). +- **FR-007**: When the active GPU becomes unavailable (driver reset, removal, sleep/resume, or other device-loss event), system MUST detect the loss and re-initialize on an available adapter (falling back to the system default if the previously-chosen adapter is no longer present), without showing an error dialog and without exiting. +- **FR-008**: System MUST collapse a burst of topology-change notifications into a single re-initialization rather than re-initializing once per notification. + +#### GPU adapter selection + +- **FR-009**: System MUST provide a user-visible control in the configuration dialog to select which GPU is used for rendering, listing each available rendering-capable adapter by its real, human-readable name. +- **FR-010**: GPU selection MUST mark the system's default adapter by appending "(default)" to its name in the list. +- **FR-011**: GPU selection MUST exclude software adapters (e.g., Microsoft Basic Render Driver) from the list. +- **FR-012**: GPU selection MUST default to "system default adapter" for new installations. +- **FR-013**: The selected GPU MUST persist across application restarts identified by adapter description. +- **FR-014**: If the previously selected adapter is not present at startup, system MUST silently fall back to the system default adapter and continue starting. +- **FR-015**: Changing the GPU selection MUST take effect on the running application within 1 second, without restart. +- **FR-016**: All monitors rendered by the application MUST use the user's selected GPU; the selection is application-wide, not per-monitor. + +#### Frame-rate efficiency + +- **FR-017**: For any monitor whose native refresh rate exceeds 60Hz, system MUST limit rendering on that monitor to approximately 60 frames per second. +- **FR-018**: For any monitor whose native refresh rate is 60Hz or less, system MUST continue to render synchronized to vertical refresh as today, with no measurable per-frame overhead from the limiter. +- **FR-019**: The frame-rate limit applies independently per monitor; mixed-refresh-rate multi-monitor setups MUST each follow the rule above. + +#### Graphics quality presets and advanced controls + +- **FR-020**: System MUST provide a Quality preset control with at least the named options "Low", "Medium", and "High", plus a "Custom" option that is selected automatically (never directly by the user) whenever the advanced controls' values do not match any named preset. +- **FR-021**: Selecting a named Quality preset MUST set all advanced graphics controls to that preset's predefined values within 1 second of the selection. +- **FR-022**: The "High" preset's values MUST produce the same visual result as the current (pre-feature) default rendering, so existing users who never touch the new controls see no change. +- **FR-023**: Adjusting any individual advanced graphics control MUST automatically switch the Quality preset to "Custom" and update an in-memory "last custom" snapshot of all advanced control values. +- **FR-024**: Selecting "Custom" from the preset control MUST restore the saved "last custom" values if any have been saved previously; otherwise the advanced controls MUST remain at their current values. +- **FR-025**: System MUST persist both the Quality preset name and (when the preset is "Custom" or when a custom set has been used at least once) the "last custom" advanced values across application restarts. + +#### Advanced graphics controls — visibility and individual controls + +- **FR-026**: System MUST provide an "advanced graphics settings" toggle control. When this toggle is off, the advanced graphics controls MUST NOT be visible and the configuration dialog MUST occupy only the space needed for the always-visible controls. +- **FR-027**: When the advanced toggle is turned on, the configuration dialog MUST dynamically grow to reveal the advanced controls; existing dialog controls below the advanced section (OK, Cancel, Reset) MUST reposition appropriately. Turning the toggle off MUST reverse this. +- **FR-028**: System MUST provide an advanced control for the number of glow passes (integer, 4 discrete positions from minimum to maximum) with labeled tick positions and a value indicator showing the current value. +- **FR-029**: System MUST provide an advanced control for the glow buffer resolution with 4 discrete positions labeled "Eighth", "Quarter", "Half", "Full" from minimum to maximum, defaulting to "Half". +- **FR-030**: System MUST provide an advanced control for the glow blur smoothness with 3 discrete positions labeled "Low", "Medium", "High" from minimum to maximum, defaulting to "High". +- **FR-031**: The existing Glow Intensity slider MUST own the on/off state of the glow effect: when its value is set to 0%, the glow effect MUST be fully disabled (no glow processing performed at all), and the slider's value indicator MUST read "0% (glow disabled)" instead of "0%". + +#### Configuration dialog — common conventions + +- **FR-032**: All percentage sliders in the configuration dialog MUST display unlabeled tick marks. Tick frequency MUST be chosen so that a tick falls at the midpoint of each slider's range where the range allows an integer midpoint, with a target of approximately 21 ticks across the range. +- **FR-033**: All discrete-position sliders (the three advanced graphics controls) MUST display a label beneath each tick position indicating the value at that tick. +- **FR-034**: Every new quality-related control (Quality preset, advanced toggle, advanced controls, Glow Intensity, Glow Size) MUST have an information indicator (an "ⓘ" / lowercase 'i' in a circle) immediately associated with it. +- **FR-035**: Information indicators MUST be reachable both by mouse hover and by keyboard focus (Tab). Activating an indicator (mouse hover, or Space/Enter while focused) MUST display a tooltip containing the indicator's descriptive text. +- **FR-036**: Every information tip's text MUST consist of one or more descriptive sentences followed by exactly one of the standardized perf-impact sentences: "Significant GPU performance impact.", "Moderate GPU performance impact.", or "Small GPU performance impact.". + +#### First-run defaults + +- **FR-037**: On first run with no saved Quality preset, system MUST select a default preset based on the system's available GPU class and the total resolution of currently-connected monitors: + - Systems with a discrete GPU available: "High". + - Systems with only integrated GPUs and a modest total monitor pixel count: "Medium". + - Systems with only integrated GPUs and a heavy total monitor pixel count (e.g., multiple high-resolution monitors): "Low". +- **FR-038**: On first run with no saved GPU selection, system MUST default to the system default adapter (same behavior as omitting any selection). +- **FR-039**: On first run with no saved multi-monitor setting, system MUST default to multi-monitor spanning enabled. + +### Key Entities *(include if feature involves data)* + +- **Multi-monitor setting**: A single yes/no preference whether MatrixRain renders on all monitors or only the primary. Defaults to yes. +- **Selected GPU adapter**: A persistent identifier (human-readable adapter description) of the user's preferred rendering adapter, or empty meaning "use system default". Used to look up the actual adapter at startup and after device-loss recovery; falls back to system default if not found. +- **Quality preset**: The currently-selected named preset (one of "Low", "Medium", "High", "Custom"). Determines the values of the advanced graphics controls when set to a named preset. +- **Advanced graphics control values**: A group consisting of (passes, resolution, smoothness, glow intensity). Driven by the Quality preset's predefined values when a named preset is selected; freely editable when Custom is selected. +- **Last custom values**: A persisted snapshot of the most recent set of advanced control values the user actually customized. Restored when the user re-selects "Custom" after having used a named preset. Does not exist until the user has customized at least once. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: After disconnecting an external monitor on a hybrid laptop while MatrixRain is running on both, the application's GPU utilization within 1 second drops to a level comparable (within 10%) to launching MatrixRain fresh with only the remaining monitor connected. +- **SC-002**: After reconnecting a previously-disconnected monitor, MatrixRain begins rendering to that monitor within 1 second without requiring the application to be restarted. +- **SC-003**: A user on a hybrid laptop can change the selected GPU through the configuration dialog and observe (via the operating system's GPU view) MatrixRain switch to using the newly-selected GPU within 1 second, without restarting the application. +- **SC-004**: On a 144Hz monitor with default settings, MatrixRain renders at no more than 65 frames per second per monitor and reduces GPU work for that monitor by at least 50% relative to v1.3 baseline behavior on the same hardware. +- **SC-005**: On a Surface-class integrated-GPU laptop running MatrixRain with default settings on its built-in display, GPU utilization is no more than 70% of the v1.3 baseline for the same hardware and content. +- **SC-006**: Every information tip in the configuration dialog can be read both by hovering with a mouse and by tabbing to its indicator and pressing Space or Enter; both methods produce the same text. +- **SC-007**: When the previously-saved GPU adapter is not present at application start, the application starts successfully on the system default adapter without showing any error dialog. +- **SC-008**: Existing users who upgrade and never open the configuration dialog see no visible change in the rendered output of MatrixRain (the "High" quality preset is visually identical to the v1.3 default). +- **SC-009**: A user can switch between named quality presets in the configuration dialog and observe the visual change on all active monitors within 1 second of selection, without restarting the application. +- **SC-010**: After customizing the advanced graphics controls and selecting a different named preset, the user can return to "Custom" and find their previously-customized values restored exactly. + +## Assumptions + +- Target operating systems are Windows 10 version 1803 or later, and Windows 11. On these versions, the operating system's modern GPU-preference APIs are sufficient to route MatrixRain's rendering to the user's chosen adapter on NVIDIA Optimus, AMD PowerXpress, and Surface-class hybrid systems. Legacy driver-export mechanisms for forcing the discrete GPU are not employed in this version of the feature; they may be added later if real-world testing on a target hybrid configuration shows the OS-level APIs are insufficient. +- The DWM compositor runs on the integrated GPU on hybrid laptops, and presenting from the discrete GPU therefore incurs a cross-adapter copy at present time. This is expected, normal, and the discrete GPU's compute headroom is assumed to far exceed that copy cost. +- A user who selects the discrete GPU expects MatrixRain's process to be routed to it; the operating system's per-application GPU preference (if set by the user separately) is assumed to either match or be deliberately overridden. We do not modify the per-application OS preference automatically. +- Single-monitor users retain their current behavior exactly: no visible change, no new dialog footprint that meaningfully shifts the layout for the single-monitor case beyond the additional graphics-quality and information-tip controls. +- Users who have not opened the configuration dialog continue to see MatrixRain's current default visual quality with no perceptible regression (the "High" preset is calibrated to be visually equivalent to the v1.3 default). +- Adapter human-readable descriptions are stable enough across reboots and driver updates to be used as the persistent identifier for the user's GPU selection. A driver update that renames an adapter would be treated as the adapter being absent and would silently fall back to the default; this is acceptable. +- Monitor refresh rates queried from the operating system are correct and stable while a given monitor is connected; if the OS cannot report a refresh rate for a monitor, fallback to standard vertical-sync rendering is acceptable. +- The configuration dialog continues to use the operating system's standard Win32 dialog rendering and accessibility behaviors; no third-party UI framework is introduced. The information-tip indicator may be a small owner-drawn control to achieve the required appearance (a lowercase "i" in a circle) while remaining keyboard-focusable. +- The "heavy" pixel-count threshold used to choose between Medium and Low first-run presets on integrated GPUs is a tunable constant; its initial value (approximately 16 million pixels — e.g., two 4K monitors, or one 8K monitor) is acceptable and can be revisited based on real-world feedback. +- Existing test infrastructure (the project's 354-test unit test suite, pure-helper + in-memory provider pattern) is the appropriate place for behavioral tests of the new pure helpers introduced by this feature. The Win32 dialog, information-tip control, owner-draw rendering, real hot-plug behavior, and real-hardware GPU utilization measurements are validated by manual QA on the user's hybrid-laptop hardware. From f7c5ae6e21a444ddcbf0fc0e505700db8aa05f48 Mon Sep 17 00:00:00 2001 From: relmer Date: Wed, 3 Jun 2026 12:10:32 -0700 Subject: [PATCH 02/56] docs(006): add tasks.md and resolve /speckit.analyze findings Add tasks.md (63 tasks across 7 non-empty phases, organized by user story; constitution-mandated tests-first for every core-library helper). Resolve cross-artifact findings from /speckit.analyze: - F1 (HIGH): FR-020 contradicted US5 acceptance scenario 7 and contracts/quality-preset-mapping.md by stating Custom was 'never directly by the user'. Updated FR-020 to permit both direct user selection and automatic system selection on drift. - F2 (MEDIUM): Cancel-revert semantics were captured only as an edge case. Added FR-031b formalizing the requirement and updated tasks T019/T035/T052 to explicitly register new controller fields in the CancelChanges/CancelLiveMode snapshot. - F3 (MEDIUM): US1 quickstart walkthrough did not cover /s mode. Added a step repeating the dock/undock test under MatrixRain.exe /s. - F4 (LOW): Tightened FR-017 from 'approximately 60 fps' to 'no more than 65 fps (target 60)' so the FR is independently testable without consulting SC-004. - F5 (LOW): Added suspend/resume cycle to T061 manual QA scope. - F6 (LOW): Added terminology assumption normalizing 'multi-monitor spanning' / 'render on all monitors' / 'multimon' as interchangeable. - F7 (LOW): FR-026 now documents the conditional default (toggle defaults to on when saved Quality preset is Custom). No CRITICAL issues. Constitution alignment confirmed unchanged.

T004 must now pass. +- [ ] T007 [US1] Modify `MatrixRainCore\RenderSystem.h` and `MatrixRainCore\RenderSystem.cpp`: change `void Present()` signature to `HRESULT Present()` (currently at `RenderSystem.cpp:1753-1758`); return the HRESULT from `m_swapChain->Present(1, 0)`. Update the single caller in `MonitorRenderContext.cpp:401` to capture the result into a local variable (still unused at this step). +- [ ] T008 [US1] Modify `MatrixRainCore\MonitorRenderContext.cpp::RenderThreadProc` (`:327-402`): after the Present call at `:401`, if `IsDeviceLost(hr)` is true, log via existing console/EHM, set an `m_deviceLost` flag, `PostMessage(m_hwnd, WM_APP_REBUILD_CONTEXTS, 0, 0)`, then `break` out of the render loop. Add `m_deviceLost` (`std::atomic`) to `MonitorRenderContext.h` (initialized false; observed by `Application` during rebuild). Include `DeviceLost.h`. +- [ ] T009 [US1] Modify `MatrixRainCore\Application.h` to add a private `RebuildCoalescer m_rebuildCoalescer;` member. Modify `MatrixRainCore\Application.cpp::HandleMessage` (`:1081…`) to add `case WM_DISPLAYCHANGE:` that calls `m_rebuildCoalescer.RequestRebuild()`; if it returns true, `PostMessage(m_mainHwnd, WM_APP_REBUILD_CONTEXTS, 0, 0)`; always return 0. +- [ ] T010 [US1] Modify `MatrixRainCore\Application.cpp::HandleMessage` `case WM_APP_REBUILD_CONTEXTS` (`:1105`): call `m_rebuildCoalescer.Consume()` at the top of the handler so the next topology change can request again.

Use `CreateDXGIFactory1` for enumeration via `IDXGIFactory1::EnumAdapters1` + `GetDesc1`; obtain `IDXGIFactory6` via `QueryInterface` and call `EnumAdapterByGpuPreference(0, DXGI_GPU_PREFERENCE_UNSPECIFIED, IID_PPV_ARGS(&defaultAdapter))` to identify the system default LUID. Skip adapters with `(desc.Flags & DXGI_ADAPTER_FLAG_SOFTWARE) != 0`. Use ComPtr for COM lifetimes; use EHM (`CHRA` for external APIs).

Default-adapter path (no LUID) preserves existing behavior. +- [ ] T033 [US3] Modify `MatrixRainCore\MonitorRenderContext.h` and `.cpp` to add `std::optional` parameter to `Initialize`; forward to `RenderSystem::Initialize`. +- [ ] T034 [US3] Modify `MatrixRainCore\Application.cpp`: in `Initialize` (or a new `ResolveAdapterOnce()` helper called from there), construct a `WindowsAdapterProvider`, call `EnumerateAdapters()`, call `ResolveAdapter(adapters, settings.m_gpuAdapter)`, cache the optional `LUID` as `m_resolvedAdapter`. Pass `m_resolvedAdapter` to every `MonitorRenderContext::Initialize` call. In `RebuildContextsForCurrentMode` (`:883-940`), re-resolve the adapter before re-initializing contexts (so a device-loss recovery after a GPU removal picks up the fallback path automatically). +- [ ] T035 [US3] Modify `MatrixRainCore\ConfigDialogController.{h,cpp}` to add `void UpdateGpuAdapter(const std::wstring& description)` mirroring `UpdateColorScheme` (`:62-78`) IN FULL: persist, update in-memory state, AND register the new field in the controller's pre-dialog snapshot consumed by `CancelChanges`/`CancelLiveMode` so dialog Cancel reverts the live preview per FR-031b. +- [ ] T036 [US3] Modify `MatrixRain\MatrixRain.rc` to add `LTEXT "GPU:"`, `COMBOBOX IDC_GPU_COMBO …, CBS_DROPDOWNLIST | WS_VSCROLL | WS_TABSTOP`, and `IDC_GPU_INFO` owner-draw button.

Modify `MonitorRenderContext::Initialize` (`.cpp`) to accept the monitor's `refreshHz` (from `DEVMODE::dmDisplayFrequency` or existing `MonitorInfo`); if `ShouldEngageFrameLimiter(refreshHz)`, construct `m_frameLimiter` with `TargetFps(60)`; else leave `nullopt`. Plumb the refresh rate through `Application.cpp` when constructing each `MonitorRenderContext`. +- [ ] T041 [US4] Modify `MatrixRainCore\MonitorRenderContext.cpp::RenderThreadProc` (`:327-402`): at the top of each loop iteration (after the `m_inTransition` skip at `:349-353` and before the `lock_guard` at `:356`), call `if (m_frameLimiter) m_frameLimiter->WaitForNextFrame();`.

Translate selection → `QualityPreset`. Call `pController->UpdateQualityPreset(preset)`; the controller updates `m_advancedValues` (via `ApplyPresetSnap`). The dialog then reflects the new values back into the three advanced sliders via `TBM_SETPOS` and re-runs `InitializeSlider`-style label updates. +- [ ] T058 [US5] Modify `MatrixRain\ConfigDialog.cpp::OnInitDialog`: create a shared `WC_TOOLTIP` window (`CreateWindowEx(..., TOOLTIPS_CLASS, ...)`). For each `IDC_*_INFO` control, register a tool with `TTM_ADDTOOL` using flags `TTF_IDISHWND | TTF_SUBCLASS`, `lpszText = LPSTR_TEXTCALLBACK`.

The render-thread loop will use this in T008 to trigger the application- level rebuild path when the GPU goes away. Covers DXGI_ERROR_DEVICE_REMOVED/RESET/HUNG/DRIVER_INTERNAL_ERROR. D3DDDIERR_* codes from GetDeviceRemovedReason are intentionally excluded; this helper deals with Present's return surface only. Tests (T003, 8 cases) and implementation (T005) are paired in this commit because principle IX requires each commit to pass tests; pure- test-only commits would break that gate. The TDD Red->Green cycle was observed locally before commit. Tests: 354 -> 362.

Together with the device-loss path from T008 this is the core fix for the ghost-monitor render thread that held GPU at ~90% after a Surface Book 3 undock. T010: Modify the WM_APP_REBUILD_CONTEXTS case to call m_rebuildCoalescer.Consume() at the top so any further topology / device-loss notifications arriving during the rebuild itself can request a follow-up. Adds m_rebuildCoalescer member to Application and includes RebuildCoalescer.h in the header. Tasks paired because both touch the same switch in Application::WindowProc. Tests: 367/367 passing. The actual hotplug behavior is covered by the US1 quickstart walkthrough (manual QA on a multi-monitor system).

This is the gate that makes the new setting actually take effect: the existing fanout in Application::Initialize already consults this predicate when deciding between single-window and per-monitor contexts. T019: Add ConfigDialogController::UpdateMultiMonitorEnabled(bool). Trivial setter; live-mode cancel-revert works automatically because the snapshot captures the entire ScreenSaverSettings struct (no per-field registration required by the existing snapshot design - this resolves analyze finding F2 more directly than the original task wording suggested). T020: Add the \"Render on all monitors\" checkbox to the dialog template (IDC_MULTIMONITOR_CHECK) and grow the dialog from 240x200 to 240x215 to fit it. Existing checkboxes shifted down 15 dlu; OK/Cancel/Reset row moved from y=175 to y=190. T021: Wire the checkbox: initialize from settings in OnInitDialog, handle the BN_CLICKED case in OnCommand, post Application::ApplyDisplayMode Change on toggle so the running app rebuilds within 1 second (FR-003). Also extend OnCancel's live-mode branch to post the same rebuild after CancelLiveMode so the reverted setting takes visual effect (FR-031b). Tests: 375/375 passing (no behavioural test regressions; new live-mode behaviour is covered by the US2 quickstart walkthrough).

Tests (T022/T023, 9 cases): - ResolveAdapter: empty saved -> nullopt; empty adapter list -> nullopt; non-matching -> nullopt; matching -> LUID; duplicate descriptions -> first match wins. - FormatAdapterLabel: non-default unchanged; default appended; empty-description-default edge case. - InMemoryAdapterProvider: returns a copy of its seed vector.

matched by LUID against the enumerated list to set AdapterInfo::m_isDefault. - Filters out DXGI_ADAPTER_FLAG_SOFTWARE adapters (Microsoft Basic Render Driver / WARP) before returning, per FR-011. - Any DXGI failure yields an empty vector; callers then use the system default-adapter path. EHM-style error handling with ComPtr for COM lifetime management. No unit tests: this layer touches real DXGI, which the project test strategy (research R-012) routes through manual QA per the US3 quickstart walkthrough. The pure ResolveAdapter/FormatAdapterLabel helpers consuming AdapterInfo are already covered by the previous commit's tests via the InMemoryAdapterProvider seam.

Default empty per FR-012/FR-038. T030: Add VALUE_GPU_ADAPTER = L\"GpuAdapter\" REG_SZ and read/write via the existing ReadString/WriteString helpers (already used for ColorScheme). Backward-compatible: absent value leaves the struct default of empty. T031: No-op for InMemorySettingsProvider (stores ScreenSaverSettings by value). T024: Add 2 GpuAdapter round-trip tests (preserves description; empty description round-trip). T032: Change RenderSystem::Initialize to accept std::optional adapterLuid (default nullopt). Store as m_requestedAdapterLuid; consumed by CreateDevice which uses EnumAdapterByLuid + D3D_DRIVER_TYPE_UNKNOWN when an explicit adapter is requested, else preserves the existing nullptr+HARDWARE path. Silent fallback on EnumAdapterByLuid failure so a vanished GPU never blocks startup (FR-014). T033: Forward the optional through MonitorRenderContext::Initialize to RenderSystem. T034: In Application::CreateRenderContexts, construct a WindowsAdapterProvider, enumerate adapters, call ResolveAdapter against the saved description, cache the result in m_resolvedAdapter. AddContext passes m_resolvedAdapter to every MonitorRenderContext::Initialize call so all monitors use the same physical GPU (FR-016). Re-resolved on every rebuild so device-lost recovery picks up the fallback path if the chosen adapter disappeared. Tests: 384 -> 386. The previously-mysterious heap-corruption failures turned out to be PCH cache staleness from the C1076/C3859 build aborts the constitution warns about; a clean rebuild restored sanity.

Stores the description in m_settings.m_gpuAdapter; cancel-revert works automatically via the snapshot. T036: Add 'GPU:' label + IDC_GPU_COMBO (CBS_DROPDOWNLIST | WS_VSCROLL | WS_TABSTOP, 170 dlu wide to accommodate long adapter names like 'NVIDIA GeForce RTX 3050 Ti Laptop GPU') to the dialog template. Dialog grew from 240x215 to 240x230; checkboxes shifted from y=110..155 to y=125..170; OK/Cancel/Reset moved from y=190 to y=205. T037: In ConfigDialog.cpp: - Add std::vector m_gpuAdapterDescriptions to DialogContext (parallel to combo entries) so OnGpuChange can map selection -> persistence string. - InitializeGpuCombo enumerates via WindowsAdapterProvider, prepends a synthetic '' entry (index 0 = empty m_gpuAdapter), then adds each non-software adapter using FormatAdapterLabel ('(default)' suffix on the default). Pre-selects whichever entry matches the saved description. - OnGpuChange reads CB_GETCURSEL, looks up the matching description in the parallel vector, calls controller.UpdateGpuAdapter, then posts a rebuild (ApplyDisplayModeChange) for live preview. - Wired into OnCommand alongside the existing IDC_COLORSCHEME_COMBO case. Tests: 386/386 (no behavioural test changes; live adapter switch is covered by US3 quickstart manual QA on a hybrid laptop).

TargetFps(60) sets the frame interval; WaitForNextFrame() returns immediately on the first call (no prior frame timestamp) and sleeps via sleep_until to the next deadline on subsequent calls. T038 (paired): 4 test cases - ShouldEngageFrameLimiter truth table across {0, 30, 59, 60, 61, 75, 120, 144, 240} Hz; WaitForNextFrame first-call-returns-immediately and second-call-sleeps-approximately (~10-50ms tolerance for Windows scheduler jitter). T040: MonitorRenderContext gets std::optional m_frameLimiter member. Initialize queries the monitor's native refresh via MonitorFromWindow -> GetMonitorInfoW -> EnumDisplaySettingsW (dmDisplayFrequency). If ShouldEngageFrameLimiter is true the limiter is constructed targeting 60 fps; otherwise m_frameLimiter stays empty and the vsync path is unchanged (FR-018 - zero per-frame overhead at <=60 Hz, single nullopt check). T041: At the top of RenderThreadProc's while loop, before deltaTime computation, call m_frameLimiter->WaitForNextFrame() if engaged. Each monitor in a mixed-refresh setup is paced independently (FR-019). Tests: 386 -> 390. The 50% GPU reduction on 144 Hz hardware is verified in T061 manual QA per SC-004.

Adds MatrixRainCore\QualityPresets.{h,cpp}: - enum class QualityPreset { Low, Medium, High, Custom }. - enum class ResolutionDivisor { Full=1, Half=2, Quarter=4, Eighth=8 }. - enum class BlurTaps { Low=5, Medium=9, High=13 }. - struct AdvancedGraphicsValues with equality operators. - LookupPresetValues: pure table (asserts on Custom; falls back to High row). - DetectActivePreset: returns the named preset whose row matches the current values, else Custom. - ApplyPresetSnap: snap to named-preset row OR restore lastCustom OR keep current (Custom-with-no-lastCustom case). - PickDefaultQualityPreset: first-run heuristic (discrete adapter -> High; integrated + <=16M pixels -> Medium; integrated + >16M pixels -> Low). Heuristic constants kDiscreteVramThresholdMb (256) and kHeavyTotalPixelsThreshold (16M) exported for direct test verification to protect against silent retunes. T042 (paired): 13 tests covering the full table, drift detection across-and-off the table, the three ApplyPresetSnap cases, all four PickDefaultQualityPreset paths (discrete, integrated-light, integrated- heavy, software-adapter-ignored), and the constants pin. FR-022 verified: High preset's values exactly match today's hardcoded rendering constants (3 passes, half res, 13-tap blur, intensity 100). Remaining US5 (T043/T044/T046-T059) will wire these helpers into the ScreenSaverSettings struct, registry persistence, RenderSystem parametric bloom, first-run heuristic at Application::Initialize, controller methods, the new dialog .rc (preset combo + advanced disclosure + 3 sliders + infotip indicators), tick-mark conventions, dynamic dialog resize, tooltip control, and owner-draw info buttons with keyboard activation. Tests: 390 -> 403.

T047: RegistrySettingsProvider: - VALUE_QUALITY_PRESET REG_SZ accepting Low/Medium/High/Custom; empty value leaves struct default (the first-run heuristic in T051 will fill in on first save). - VALUE_LASTCUSTOM_GLOW_INTENSITY/PASSES/RESOLUTION/SMOOTHNESS DWORDs: ALL FOUR required to honor; any missing -> m_lastCustom stays nullopt (registry-schema contract). - VALUE_SHOW_ADVANCED_GRAPHICS DWORD bool. Load applies preset row to m_advancedValues automatically when preset is named, or restores LastCustom if preset == Custom and snapshot is present. Save always writes preset + advanced + LastCustom when the optional has a value, plus showAdvancedGraphics. T048: No-op for InMemorySettingsProvider (stores by value). T049: Parametric bloom in RenderSystem: - Three blur shader variants per direction (5/9/13-tap) compiled at startup: m_blurHorizontalPS / PS9 / PS5, same for vertical. - ApplyBloom selects the variant matching m_blurTaps at bind time (no dynamic-loop overhead). - Pass count is m_blurPasses (clamped 1..4) replacing the hardcoded 3. - Bloom buffer size and viewport divided by static_cast( m_bloomResolutionDivisor) (1=Full, 2=Half, 4=Quarter, 8=Eighth). - SetBlurPasses / SetBloomResolution / SetBlurTaps added to IRenderSystem and SpyRenderSystem. - SharedState + SharedState::Snapshot extended with blurPasses, bloomResolutionDivisor, blurTaps; MonitorRenderContext::RenderThreadProc pushes them to RenderSystem each frame. - SetBloomResolution recreates the bloom textures on change so a live Resolution-slider tweak rebuilds correctly. T050: When m_glowIntensity == 0 the entire bloom pipeline is bypassed in Render: extract/blur/composite are skipped and the scene texture is composited directly to the backbuffer via the existing composite shader (FR-031 'glow disabled' = true off, not just darker). Tests: 403/403 still passing after a clean rebuild. The intermittent PCH C1076/C3859 cache-staleness gotcha hit again on the way; documented once already (commit message on T024..T034) -- when it strikes, do a clean rebuild rather than trusting the test output.

Capture IsFirstRun() from ApplicationState (set when Load() returns S_FALSE - no registry key existed). On a brand-new install: - Enumerate adapters via WindowsAdapterProvider. - Compute totalMonitorPixels by summing each MonitorInfo's Width()*Height(). - Call PickDefaultQualityPreset(adapters, totalPixels) and persist via ApplicationState::ApplyFirstRunQualityPreset() (new method). - Seed SharedState with the chosen preset's advanced values so the first frame renders correctly. Existing installs (key present in registry, no QualityPreset value): - In-class default of High preserves today's exact rendering (FR-022). - SharedState seeded from loaded advanced values for the render thread. T052: Three new ConfigDialogController methods: - UpdateQualityPreset(preset): calls ApplyPresetSnap, writes back advanced values. Live-mode pushes the resulting glow intensity to ApplicationState for the snapshot path. - UpdateAdvancedGraphicsValues(values): writes new values AND always updates LastCustom (FR-023 - any direct edit captures user state even if it coincidentally matches a named preset row), then recomputes m_qualityPreset via DetectActivePreset (typically flips to Custom). - UpdateShowAdvancedGraphics(show): persists the disclosure toggle state. Cancel-revert is automatic via the snapshot for all three (m_settings captures the new fields by value). ApplicationState gains IsFirstRun() and ApplyFirstRunQualityPreset(). Tests: 403/403 still passing.

Adds a 'Graphics quality' GROUPBOX containing: - IDC_QUALITY_PRESET_COMBO (Low/Medium/High/Custom) - IDC_GRAPHICS_ADVANCED_CHECK ('Show advanced graphics settings' toggle) - IDC_GLOWPASSES_SLIDER + LABEL (1..4) - IDC_GLOWRES_SLIDER + LABEL (Eighth/Quarter/Half/Full) - IDC_GLOWSMOOTH_SLIDER + LABEL (Low/Medium/High) Buttons and remaining checkboxes pushed down. Info indicators (IDC_*_INFO) reserved in T002 but the owner-draw + tooltip surface (FR-034/FR-035/FR-036) is intentionally deferred to a follow-up commit. T054: Extend InitializeSlider to send TBM_SETTICFREQ per the locked tick-mark contract: Density freq=5 (21 ticks), AnimSpeed freq=5 + explicit TBM_SETTIC at 100 (21 ticks total), GlowIntensity freq=10 (21 ticks), GlowSize freq=5 (31 ticks, midpoint at 125). FormatPercentLabel special- cases Glow Intensity at 0% to read '0% (glow disabled)' per FR-031. New InitializePassesSlider / InitializeResolutionSlider / InitializeSmoothnessSlider for the three discrete sliders with mapped labels; FormatResolutionLabel/FormatSmoothnessLabel helpers. T056: WM_HSCROLL handler extended: - Each new discrete slider calls UpdateAdvancedGraphicsValues with the new value, then reflects DetectActivePreset(values) back to the preset combo (auto-flips to Custom on drift per FR-023). - Glow Intensity is now part of the advanced value set; moving it also drifts the preset to Custom. T057: OnQualityPresetChange CBN_SELCHANGE handler: - Calls UpdateQualityPreset(preset), which snaps advanced values via ApplyPresetSnap. - Reflects the snapped values back into the four sliders (Glow Intensity + Passes + Resolution + Smoothness) so the UI matches the new preset. OnGraphicsAdvancedCheck handler persists IDC_GRAPHICS_ADVANCED_CHECK state via UpdateShowAdvancedGraphics. T055 (dynamic dialog resize on toggle) deferred to follow-up: today the advanced sliders are always visible. Functionally complete for US5 acceptance scenarios 1-9; the disclosure-and-resize behavior of scenarios 2-3 is partial (the toggle is wired to the setting but does not hide controls or resize the dialog). OnCommand wires IDC_QUALITY_PRESET_COMBO (CBN_SELCHANGE -> preset change) and IDC_GRAPHICS_ADVANCED_CHECK (BN_CLICKED -> toggle handler). Tests: 403/403. US5 functionality verifiable end-to-end via the quickstart walkthrough except for the disclosure-resize visuals and the infotip tooltips.

Then collapses to the user's saved IDC_GRAPHICS_ADVANCED_CHECK state via ApplyAdvancedGraphicsVisibility. ApplyAdvancedGraphicsVisibility: - ShowWindow each advanced control (SW_SHOW / SW_HIDE). - SetWindowPos the dialog itself to grow/shrink by the captured block height delta. - GetWindow + GW_CHILD/GW_HWNDNEXT walks every child control and moves the ones below the advanced block (excluding the advanced controls themselves) up or down by the same delta. Naturally repositions OK/Cancel/Reset, the four mode checkboxes, and any other below-block controls without the .rc needing per-control y-coordinate tracking.

These are real BUTTONs (focusable and tabbable) rather than the originally-spec'd owner-draw circles; the spec calls for "i in a circle" but the focusability + tooltip surface (the substance of FR-034/FR-035/FR-036) matters more than the exact glyph for v1.4. Owner-draw cosmetic polish can land in a follow-up if desired. CreateAndRegisterTooltip creates a single shared WC_TOOLTIPS window in OnInitDialog and registers each IDC_*_INFO button as a tool with TTF_IDISHWND | TTF_SUBCLASS, with per-tool text supplied via LPSTR_TEXTCALLBACKW. ConfigDialogProc handles TTN_GETDISPINFO[W] by mapping the tool's hwnd back to an IDC_*_INFO control id via GetDlgCtrlID and returning the locked infotip text from GetInfoTipText. TTM_SETMAXTIPWIDTH=300 dpx wraps long text into a readable multi-line tip. GetInfoTipText returns the seven locked strings per FR-036 (each ends with exactly one of "Significant", "Moderate", or "Small GPU performance impact."). Mouse hover on each info button shows the matching tooltip. Keyboard activation (Tab to button, Space/Enter) is partially covered: the buttons are focusable per WS_TABSTOP, but the BN_CLICKED -> manual TTM_TRACKACTIVATE wiring required to pop the tooltip via keyboard is deferred to a follow-up (T059 in tasks.md). Tests: 403/403.

CreateAndRegisterTooltip now also registers a single TTF_TRACK | TTF_ABSOLUTE tool keyed by sentinel uId=kTrackTipUId for keyboard- activated tips. OnInfoButtonClick (called from OnCommand BN_CLICKED on any IDC_*_INFO button - which fires for both mouse click AND Space/Enter while the button has keyboard focus): - TTM_UPDATETIPTEXTW updates the TRACK tool's text to GetInfoTipText for the matching info id. - TTM_TRACKPOSITION positions the tip just below/right of the button's screen rect. - TTM_TRACKACTIVATE TRUE shows it. - SetTimer (kInfoTipDismissTimerId, 5000ms) for auto-dismiss. ConfigDialogProc handles: - WM_TIMER (kInfoTipDismissTimerId) -> DismissInfoTip. - WM_ACTIVATE WA_INACTIVE -> DismissInfoTip (lose-focus dismisses). Mouse hover continues to work via the original TTF_SUBCLASS tools from T058; keyboard activation uses the new TRACK tool. SC-006 fully satisfied: every infotip can be read by hovering AND by tabbing-then- Space/Enter. Tests: 403/403.

The render context is rebuilt automatically; this fixes the previously-reported "GPU stuck at ~90% after undocking a Surface Book 3" defect where the ghost monitor's render thread continued processing forever. +- **User Story 2 (P1) — Optional multi-monitor spanning.** New "Render on all monitors" checkbox in the configuration dialog (default on). Toggling it live applies within 1 second; Cancel reverts. +- **User Story 3 (P2) — GPU adapter selection.** New "GPU" dropdown in the configuration dialog listing each real adapter name (with "(default)" appended to the system default) plus a `` sentinel entry. Software/WARP adapters are excluded. Selection persists by description string; if the saved adapter is missing at startup, the application silently falls back to the system default. Live device-switch takes effect within 1 second. +- **User Story 4 (P2) — Frame cap on high-refresh monitors.** Per-monitor `FrameLimiter` engages only when the monitor's native refresh exceeds 60 Hz, capping that monitor's rendering to 60 FPS. At ≤60 Hz the existing vsync path is preserved with no measurable per-frame overhead. Substantially reduces GPU work on 144Hz / 165Hz laptop displays. +- **User Story 5 (P3) — Graphics quality preset spectrum.** New "Quality" dropdown (Low / Medium / High / Custom) in a "Graphics quality" group box. Advanced disclosure toggle reveals three discrete sliders — Passes (1-4), Resolution (Eighth / Quarter / Half / Full), Smoothness (Low / Medium / High) — and the dialog dynamically grows/shrinks when toggled. Each quality-related control has an "i" infotip indicator; hovering or tabbing-then-pressing-Space/Enter reveals a tooltip with a description and standardized GPU-performance-impact phrase. Glow Intensity at 0% now disables the entire bloom pipeline (true off, not just darker). First-run heuristic picks a starting preset based on detected GPU class and total monitor pixel count (discrete → High; integrated + modest load → Medium; integrated + heavy load → Low). Custom-drift behaviour: any direct edit of an advanced control auto-flips the preset to Custom and saves the resulting values for restoration when the user later re-selects Custom. + +### Changed + +- Bloom pipeline is now runtime-parametric: blur passes (1-4), bloom buffer resolution (full/half/quarter/eighth), and blur kernel taps (5 / 9 / 13) are all selectable per-frame from the quality preset / advanced sliders. Three blur shader variants are compiled at startup so the tap-count switch is free at draw time. +- Default settings on a fresh install now pick a quality preset matched to detected hardware rather than always using the maximum. + +### Known Issues + +- Infotip indicators are real focusable BUTTON controls rendering "i" text rather than the spec'd owner-drawn "i-in-a-circle" glyph. The accessibility surface (focus, hover tooltip, keyboard tooltip activation) is complete; only the cosmetic appearance is a follow-up. + ## [1.3.1984] - 2026-06-03 ### Added diff --git a/specs/006-multimon-gpu-efficiency/spec.md b/specs/006-multimon-gpu-efficiency/spec.md index 5b59630..bed8521 100644 --- a/specs/006-multimon-gpu-efficiency/spec.md +++ b/specs/006-multimon-gpu-efficiency/spec.md @@ -2,7 +2,7 @@ **Feature Branch**: `006-multimon-gpu-efficiency` **Created**: 2026-06-03 -**Status**: Draft +**Status**: Implemented (60/63 tasks committed; T060/T061/T063 polish documented in tasks.md) **Input**: User description: "Improve MatrixRain v1.4: make multi-monitor rendering optional (default on); add a GPU adapter selection so users on hybrid laptops can pick integrated vs discrete; respond appropriately to monitors and GPUs being added or removed while running (current behavior leaves a 90% GPU load after undocking a Surface Book 3); and reduce overall GPU usage on hybrid hardware through a frame-rate cap on high-refresh monitors and a graphics quality preset spectrum (Low / Medium / High / Custom) with advanced controls behind a disclosure toggle and accessible information tips." ## User Scenarios & Testing *(mandatory)* From 0bd29c8d3360fffa204135f69983438238fe4a4a Mon Sep 17 00:00:00 2001 From: relmer Date: Wed, 3 Jun 2026 17:27:02 -0700 Subject: [PATCH 27/56] fix(006): live preview of preset/advanced changes (gap discovered post-impl) US5 had a real live-preview hole I missed during T051/T052: SharedState. blurPasses / bloomResolutionDivisor / blurTaps were initialized in Application::InitializeApplicationState from loaded settings, but no callback updated them when ConfigDialogController changed values during a live dialog session. Effect: moving an advanced slider or switching preset persisted correctly but did NOT show on the running monitors until restart, breaking SC-009 ('user can switch between named quality presets... and observe the visual change... within 1 second of selection, without restarting'). Fix: - ApplicationState gains SetAdvancedGraphics(values) + a m_advancedGraphicsChangeCallback + RegisterAdvancedGraphicsCallback, mirroring the existing per-knob callback pattern (RegisterGlow IntensityCallback etc). - Application::InitializeApplicationState registers a callback that updates SharedState.glowIntensityPercent, blurPasses, bloomResolutionDivisor, and blurTaps as a unit (under m_sharedState. mutex). - ConfigDialogController::UpdateQualityPreset and UpdateAdvancedGraphicsValues now call appState->SetAdvancedGraphics in live mode, replacing the previous single-field push that only updated GlowIntensity. The next snapshot the render thread takes (next frame) sees the new values and pushes them to RenderSystem via the IRenderSystem setters landed in T046-T050. Tests: 410/410 still pass.

This matches the spec's 'lowercase i in a circle' requirement without needing WM_DRAWITEM owner-draw plumbing. The character is in the Enclosed Alphanumerics block and renders natively in Segoe UI on Windows 10 / 11 (and Segoe UI Symbol as fallback) so no font installation is required. The original research.md R-009 considered and rejected a Unicode-glyph approach citing 'font-availability fragility, not focusable'. The not-focusable concern only applied to using a STATIC control; we use real PUSHBUTTONs (already focusable, tabbable, Space/Enter activates BN_CLICKED). Font availability is a non-issue on the project's Win11 target. MatrixRain.rc is now saved as UTF-8 with BOM so the RC compiler reads the ⓘ character literal correctly. Updates CHANGELOG.md to remove the known-issue note about info indicators rendering plain 'i' text. Tests: 410/410.

From ead52d874a4b585e7b71c9a491300331935ce081 Mon Sep 17 00:00:00 2001 From: relmer Date: Wed, 3 Jun 2026 20:56:41 -0700 Subject: [PATCH 33/56] fix(006): hide all 12 advanced-block controls, shrink groupbox, widen labels MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three bugs from the user's screenshot of the collapsed Graphics-quality group: 1. Advanced disclosure only hid 6 of 12 controls (sliders + value labels). The 3 prompt LTEXTs and 3 ⓘ info buttons remained visible, and were moved up with the rest of the below-block controls by ApplyAdvanced GraphicsVisibility, overlapping the Quality combo and the advanced-toggle checkbox. Fix: give the 3 prompt labels real ids (IDC_GLOWPASSES_PROMPT, IDC_GLOWRES_PROMPT, IDC_GLOWSMOOTH_PROMPT) instead of IDC_STATIC, and add all 12 advanced-block control ids (prompt + slider + value + info x 3 rows) to kAdvancedGraphicsControlIds so the show/hide and the move-below-block-by-delta logic both treat them as a unit. 2. The 'Graphics quality' GROUPBOX kept its expanded height of 110 dlu even when the advanced rows were hidden, enclosing empty space at the bottom. Fix: give the groupbox its own id (IDC_QUALITY_GROUPBOX) and shrink its height by the advanced block delta whenever the disclosure collapses (and re-grow on expand) inside ApplyAdvancedGraphicsVisibility. 3. The 'Glow intensity:' prompt label was being clipped to 'Glow' because the original LTEXT width of 40 dlu was set for shorter labels like 'Density:' / 'Speed:'. This was a pre-existing v1.3 bug exposed alongside the others. Fix: widen all four percentage-slider prompt labels to 50 dlu and shift the trackbars from x=50 to x=60 (trackbar width reduced from 130 to 120 to keep the right margin / value-label position constant). Tests: 410/410.

charset=UTF-8 Content-Transfer-Encoding: 8bit User feedback items 1-6 from screenshot: 1+2+3. Infotips were rendering with PUSHBUTTON chrome (raised bevel, pressed state, hover highlight). Changed to BS_OWNERDRAW buttons (no native frame) and added a WM_DRAWITEM handler in ConfigDialogProc that draws ONLY the ⓘ glyph - transparent background, COLOR_WINDOWTEXT, DT_CENTER | DT_VCENTER | DT_SINGLELINE | DT_NOCLIP. No button border, no pressed/hover state visuals. Glyph size: created a 1.5x-size HFONT in OnInitDialog from the dialog's own font (WM_GETFONT -> GetObject -> LOGFONT with lfHeight scaled by 3/2; CreateFontIndirectW). Owned by DialogContext, destroyed in OnDestroy. Info button rects grown from 12x12 to 14x14 dlu to give the larger glyph some padding (DT_NOCLIP allows overflow if needed). Focus indication: DrawFocusRect when ODS_FOCUS is set so Tab-to-button is still visually obvious; otherwise no chrome. 4. Tooltip on hover (TTF_SUBCLASS) and on click/Space/Enter when focused (BN_CLICKED -> TTM_TRACKACTIVATE) was already wired in T058/T059. BS_OWNERDRAW preserves WS_TABSTOP focusability and BN_CLICKED notify behavior, so all three paths continue to work for the new owner-draw buttons. 5. GPU dropdown had both a synthetic '' entry AND the real default adapter labeled with ' (default)' - redundant and confusing. Removed the synthetic entry; InitializeGpuCombo now populates only the real adapters. Selection logic: prefer the saved description match; otherwise auto-select the (default)-marked adapter so the UI always highlights what is actually running. An empty saved description now means 'fall back to default at resolution time' but the user picks the default adapter by name from the list rather than via a sentinel. 6. GPU combo width 170 -> 165 so its right edge lands at x=225, aligned with the right edge of the right-column ⓘ buttons (which moved from x=213 to x=211 so width 14 still ends at x=225). IDC_GRAPHICS_ADVANCED _INFO also moved from x=190 to x=211 to share the column. Items 7+8 from the screenshot (orphan advanced labels + groupbox not shrinking) were already fixed in commit ead52d8; the user's screenshot predates that commit. Tests: 410/410.

Replace with direct range/freq computation (same TickFrequencyForSliderId helper now used by both InitializeSlider and the custom-draw). Layout overhaul addressing the rest of the screenshot feedback: - Vertically center prompt label + infotip + slider value on each slider's middle (label_y = slider_y + 6, info_y = slider_y + 3). - Left-align all sliders and comboboxes at x=74; right-align all value labels and comboboxes at x=233 (dialog right margin). - Bump top margin so the density slider's focus rect no longer clips against the title bar. - Remove the infotip on 'Show advanced graphics settings' per UX feedback. - Move Reset to bottom-left and keep OK/Cancel at bottom-right. - Activate tooltip control on creation (TTM_ACTIVATE) — was defaulting to inactive, hover tips weren't firing. - Dialog grows from 240x325 to 240x360 to absorb the new spacing.

Rename 'Passes' / 'Resolution' / 'Smoothness' to 'Glow passes' / 'Glow resolution' / 'Glow smoothness' so the prompts identify what they actually control. - Remove the 'Show advanced graphics settings' checkbox and always show the three glow tuning sliders (deletes the disclosure show/hide / dialog-resize / groupbox-resize logic and the m_advancedExpanded / m_advancedBlockHeight DialogContext fields). - Reset button now also restores Render-on-all-monitors, GPU adapter, quality preset slider + label, and the three glow tuning sliders (it previously only covered the v1.3 controls). - Layout column rework: all prompts at x=15 w=58 (fits 'Glow smoothness:'), infos at x=74, sliders at x=90 w=110, combos at x=90 w=143, values at x=205 w=28 — all right-edge aligned at x=233. - Dialog height shrinks 360 -> 340 dlu now that the show-advanced row is gone. Code/data removal: - Drop ScreenSaverSettings::m_showAdvancedGraphics + the ShowAdvancedGraphics registry value + ConfigDialogController::UpdateShowAdvancedGraphics + the matching test. - Drop ConfigDialog.cpp's kAdvancedGraphicsControlIds list, ApplyAdvancedGraphicsVisibility, CaptureAdvancedBlockHeight, OnGraphicsAdvancedCheck. Fade-timer hotkey: - Remove the VK_OEM_3 (backtick) debug-only InputSystem case that toggled ToggleDebugFadeTimes — the dialog's 'Show fade timers' checkbox remains. - Drop the matching backtick paragraph + screenshot from README.md.

The render context is rebuilt automatically; this fixes the previously-reported "GPU stuck at ~90% after undocking a Surface Book 3" defect where the ghost monitor's render thread continued processing forever. - **User Story 2 (P1) — Optional multi-monitor spanning.** New "Render on all monitors" checkbox in the configuration dialog (default on). Toggling it live applies within 1 second; Cancel reverts. -- **User Story 3 (P2) — GPU adapter selection.** New "GPU" dropdown in the configuration dialog listing each real adapter name (with "(default)" appended to the system default) plus a `` sentinel entry. Software/WARP adapters are excluded. Selection persists by description string; if the saved adapter is missing at startup, the application silently falls back to the system default. Live device-switch takes effect within 1 second. +- **User Story 3 (P2) — GPU adapter selection.** New "GPU" dropdown in the configuration dialog listing each real adapter name (with "(default)" appended to the system default). Software/WARP adapters are excluded. Selection persists by description string; if the saved adapter is missing at startup, the application silently falls back to the system default. Live device-switch takes effect within 1 second. - **User Story 4 (P2) — Frame cap on high-refresh monitors.** Per-monitor `FrameLimiter` engages only when the monitor's native refresh exceeds 60 Hz, capping that monitor's rendering to 60 FPS. At ≤60 Hz the existing vsync path is preserved with no measurable per-frame overhead. Substantially reduces GPU work on 144Hz / 165Hz laptop displays. -- **User Story 5 (P3) — Graphics quality preset spectrum.** New "Quality" dropdown (Low / Medium / High / Custom) in a "Graphics quality" group box. Advanced disclosure toggle reveals three discrete sliders — Passes (1-4), Resolution (Eighth / Quarter / Half / Full), Smoothness (Low / Medium / High) — and the dialog dynamically grows/shrinks when toggled. Each quality-related control has an "i" infotip indicator; hovering or tabbing-then-pressing-Space/Enter reveals a tooltip with a description and standardized GPU-performance-impact phrase. Glow Intensity at 0% now disables the entire bloom pipeline (true off, not just darker). First-run heuristic picks a starting preset based on detected GPU class and total monitor pixel count (discrete → High; integrated + modest load → Medium; integrated + heavy load → Low). Custom-drift behaviour: any direct edit of an advanced control auto-flips the preset to Custom and saves the resulting values for restoration when the user later re-selects Custom. +- **User Story 5 (P3) — Graphics quality preset spectrum.** New "Quality" slider (Low / Medium / High / Custom) in a "Graphics quality" group box.

Custom-drift behaviour: any direct edit of an advanced control auto-flips the preset to Custom and saves the resulting values for restoration when the user later re-selects Custom. ### Changed - Bloom pipeline is now runtime-parametric: blur passes (1-4), bloom buffer resolution (full/half/quarter/eighth), and blur kernel taps (5 / 9 / 13) are all selectable per-frame from the quality preset / advanced sliders. Three blur shader variants are compiled at startup so the tap-count switch is free at draw time. - Default settings on a fresh install now pick a quality preset matched to detected hardware rather than always using the maximum. +- Reset button in the configuration dialog now restores every v1.4 setting (multi-monitor, GPU, quality preset, glow passes / resolution / smoothness) in addition to the v1.3 controls it previously covered. + +### Removed + +- The backtick (`) debug hotkey that toggled the per-character fade-timer overlay.

Starting with a short description of the app's purpose and behavior, SpecKit generated a detailed [spec](specs/001-matrix-rain/spec.md) with five user stories, assigned priorities to them, and generated acceptance criteria for each. It came up with a set of edge cases to be clarified and tested, and 27 functional requirements. From 3680068327da434eeacb4ad82c11f12b9053277c Mon Sep 17 00:00:00 2001 From: relmer Date: Thu, 4 Jun 2026 06:25:03 -0700 Subject: [PATCH 39/56] fix(ui): focus rect erase, symmetric margins, working tooltips, drop Eighth + add GPU load % 1. Owner-draw info button now FillRects with COLOR_3DFACE before painting the glyph so XOR-drawn focus rects from prior paints are properly erased when focus moves away. 2. Right margin matches left margin (15 dlu). Combos / value labels / Cancel button right-edges are all at x=225; Reset moves to x=15 to match label left margin. Sliders shrink to w=102, value labels to x=197. 3. Replace TTF_SUBCLASS (unreliable on BS_OWNERDRAW buttons) with manual SetWindowSubclass + TTM_RELAYEVENT so hover/click tooltips actually fire. 4. Remove Eighth from the glow-resolution slider (range 0..2 mapping Quarter/Half/Full). The ResolutionDivisor::Eighth enum value is preserved for backward compat; if a saved configuration still has it the slider just snaps to Quarter on display. 5. Add 'GPU NN%' to the debug statistics line. RenderSystem now wraps each frame in D3D11 TIMESTAMP_DISJOINT + TIMESTAMP queries (3-frame pipeline so reads don't stall), computes GPU work / vsync interval, and exposes a smoothed (EMA) percentage to the FPS overlay. Link comctl32.lib in ConfigDialog.cpp for SetWindowSubclass / DefSubclassProc / RemoveWindowSubclass.

charset=UTF-8 Content-Transfer-Encoding: 8bit GPU load now matches Task Manager's 'engine busy %' intuition: gpu_work_ms / wall_clock_ms between Render calls. Previous impl divided by 1000/fps which (a) is 0 during fps warmup and (b) gates the EMA update on params.fps>0 — meaning if the queries took a few frames to flush we silently lost the data and never updated. New pipeline: - 6 query slots (deeper headroom for vsync-stalled GPUs). - Walk back from newest-issued slot looking for one whose 3 GetData calls all return S_OK (vs. failing the entire read if the specific N-2 slot hadn't flushed). - Wall-clock interval via QueryPerformanceCounter, independent of the fps counter; falls back to 16.667ms if first frame. - 85/15 EMA smoothing (faster response than the old 90/10). - First reading bypasses EMA so the displayed value isn't 0 for the first ~30 frames. - m_gpuHaveAnyReading flag: stats overlay shows 'GPU --%' until we have a real measurement, never the misleading 'GPU 0%'. Also added a layout comment block to MatrixRain.rc documenting the column conventions (label/info/slider/value column x positions, slider class + height rationale) to prevent the slider-widths-drifting-between-builds issue.

Root cause: the project had no application manifest at all, so the OS gave us comctl32 v5. Fix: add MatrixRain.manifest declaring dependency on Microsoft.Windows.Common-Controls 6.0.0.0. Also call InitCommonControlsEx(ICC_BAR_CLASSES | ICC_STANDARD_CLASSES | ICC_WIN95_CLASSES) at startup so the v6 trackbar/button/combobox window classes are registered. The manifest also declares per-monitor v2 DPI awareness (matching the runtime SetProcessDpiAwarenessContext call) and Windows 10/11 compat so the OS skips shim-layer heuristics.

Matching what the Processes-tab GPU column reports. Displays 'GPU --%' until the first successful collection (PDH always returns no data on the first call), then 'GPU NN%' thereafter. Also tightened InitCommonControlsEx flags from ICC_WIN95_CLASSES | ICC_STANDARD_CLASSES | ICC_BAR_CLASSES (the first being a superset of the third) to just ICC_STANDARD_CLASSES | ICC_BAR_CLASSES — exactly what we use (button/edit/combobox/static/trackbar/tooltip).

Dialog widened 240 -> 300 dlu. All sliders stretched 102 -> 162 dlu; combos 135 -> 195 dlu; value-label column shifted 197 -> 257 dlu. Right margin still 15 dlu so right-edge controls now end at x=285. Groupbox widened 233 -> 286 to match the new dialog width. 2. Removed the NM_CUSTOMDRAW tick-mark handler (DrawTrackbarDarkTicks + IsTrackbarSliderId + the WM_NOTIFY NM_CUSTOMDRAW block). The original justification was that unthemed v5 trackbar ticks were nearly invisible — but with the comctl32 v6 manifest now in place, the themed trackbar draws perfectly readable ticks itself. TickFrequencyForSliderId stays since InitializeSlider still uses it to set TBM_SETTICFREQ. 3. Bottom checkboxes reflowed into two columns: Left (x= 15, w=130): Start in fullscreen, Render on all monitors Right (x=150, w=135): Show debug statistics, Show fade timers Saves 30 dlu of vertical space; dialog height shrinks 340 -> 320. 4. Bottom buttons now respect the 15-dlu left/right margins: Reset at x=15, OK at x=180, Cancel at x=235 (right edge at x=285 matching the slider/combo right edge).

My label y values were positioned to center on the whole slider rect (slider_y + 6 for an 8-DLU label inside a 20-DLU slider), which put them ~4 DLU below the channel — visible misalignment compared to native dialogs like Mouse Properties where labels sit at the channel line. Moved every per-slider prompt label and value label up 4 DLU (label_y = slider_y + 2 instead of slider_y + 6). Also moved the inline ⓘ info buttons up 3 DLU (info_y = slider_y, was slider_y + 3) so the 14-DLU info button centers on the channel as well.

That phrasing matches the Performance-tab per-engine GRAPH, which displays total system GPU utilization for the engine — NOT the per-process Processes-tab column. When a windowed app renders, the GPU work splits between: - the app's own 3D engine context (our process) - the DWM compositor's 3D engine context (does the final desktop composition for visible windows) My PID-filtered metric only saw our process's portion and chronically underreported by ~10pp — exactly the DWM compositor's share for displaying us. For a debug overlay on a rendering app, total-system is the more meaningful number anyway (DWM compositing is genuinely part of the cost of putting our frame on screen). Dropped the PID filter; the counter path is now '\\GPU Engine(*)\\Utilization Percentage' with the same per-engtype SUM + cross-engtype MAX reducer.

For a debug overlay 'how much GPU is this app costing', per-process is the right number. Restored PID filtering by parsing 'pid_NNNN_' out of each instance name (counter path stays '\\GPU Engine(*)' so PDH wildcard expansion always sees all engine instances).

(High) Glow intensity persisted incorrectly across the two parallel fields (top-level ScreenSaverSettings::m_glowIntensityPercent vs m_advancedValues.m_glowIntensityPercent). Picking the Low preset and restarting lost the 75 percent and reverted to the default 100. Fixed by mirroring the advanced-cluster value into the top-level field in ApplyFirstRunQualityPreset, UpdateQualityPreset, and UpdateAdvancedGraphicsValues so Save persists the right value and the next launch's seed-from-top-level is consistent. 2. (Medium) Render-thread device-lost path now posts WM_APP_DEVICE_LOST (new) instead of WM_APP_REBUILD_CONTEXTS directly. The new HandleMessage case funnels through m_rebuildCoalescer so an N-monitor burst (driver reset, sleep/resume, eGPU unplug) collapses to a single rebuild instead of N back-to-back rebuilds. 3. (Medium) GpuLoadMonitor wildcard counter is now re-expanded every 10s by closing and re-opening the PDH query. Previously the wildcard was expanded once at AddCounter time and never saw GPU engine instances that appeared later (which is exactly what happens after the device-lost recovery the PR introduced). Class refactored along the way into four focused helpers: Initialize / ReleaseQuery / EnsureQueryReady / CollectCounters / AggregateMaxPerEngineType. GetLoadPercent is now a cache-and-throttle gate that calls the helpers. 4. (Medium) Stripped per-declaration function-header banner blocks from new .h files (QualityPresets.h, AdapterSelection.h, FrameLimiter.h, IAdapterProvider.h) per the convention that the 80-char //// blocks belong on .cpp definitions, not .h declarations. Replaced with concise single-line // doc comments above each declaration. 5. (Medium) Added the standard function-header //// blocks to the first 16 functions in ConfigDialogController.cpp so the file matches the convention used throughout the rest of the codebase (the lower half already had them). 6. (Low) Left Initialize without an Error: label because /WX rejects the resulting unreferenced-label warning. The convention's "always include Error:" guidance is incompatible with the project's warning settings when no CHR/CBR path exists. Documented the choice with a comment so future additions are obvious. 454 tests pass on x64. Both x64 Debug and ARM64 Debug build clean.

(Bug) RenderSystem.cpp no-glow composite path was binding only 1 SRV (slot t0 = scene) but the composite PS samples 2 slots (scene + bloom). PSSetShaderResources with numResources=1 leaves slot t1 unchanged, so the composite would sample stale bloom from a previous frame when glow was toggled off mid-run. Bind a null SRV at slot 1 and pass num=2. 2. (Bug) IsDeviceLost was missing D3DDDIERR_DEVICEREMOVED, which can surface during real device-removal flows and was explicitly called out in the design notes. Added the case plus a paired unit test. The constant lives in the kernel-mode DDI header (d3dukmdt.h) so it's defined inline at both call sites with its documented stable value. 3. (Contract) IDC_GLOWSIZE_SLIDER tick frequency was 10, which left no tick at the midpoint (125) — violating the documented midpoint rule in contracts/tick-mark-conventions.md. Changed to 25, giving ticks at 50/75/100/125/150/175/200 (7 ticks; preserves the recent "halve" intent of fewer ticks AND keeps the midpoint tick). 4. (Contract) WindowsAdapterProvider::EnumerateAdapters was returning partial results on mid-enumeration DXGI failures (CBREx forces hr=S_OK and goto Error returned whatever was accumulated). Per contracts/adapter-provider.md the function must return an empty vector on any DXGI failure. Switched the EnumAdapters1 failure path to a dxgiFailure flag that the Error: handler tests to clear the vector. Not addressed (intentional / out of scope): - IDC_GLOWSIZE_INFO tooltip lacks the standardized perf-impact line: intentional per commit edbdeb1 ("drop perf-impact from Glow size"). - Eighth removed from IDC_GLOWRES_SLIDER: intentional per commit 3680068 ("drop Eighth + add GPU load %"). - "Advanced graphics settings" disclosure checkbox absent from IDC_GRAPHICS_ADVANCED_*: intentional per commit 09e6285 ("remove advanced disclosure"). The IDs remain in resource.h as reserved. - Version.h auto-mutation: noted, not committing the per-build bump. Structural fix (split VERSION_BUILD into a gitignored VersionBuild.h) has release.yml implications worth a dedicated discussion; tracking separately. ARM64 + x64 Debug build clean, 410/410 tests pass (was 409 — new D3DDDIERR_DEVICEREMOVED case adds one).
