ALPA is a comprehensive system auditing and optimization utility developed by amazingb01 (Adiru). It provides deep insight into Windows internals, helping gamers and power users diagnose input lag, micro-stutters, and hardware bottlenecks in real-time.
- DPC & ISR Analysis: Uses Event Tracing for Windows (ETW) to intercept kernel calls.
- Real-Time Statistics: Tracks Current, Average, Minimum, and Maximum latency (in µs) for every active driver.
- Spike Detection: Automatically logs high latency spikes (>500µs) causing frame drops.
- CSV Export: Automatically saves a detailed
ALPA_Drivers_Report.csvupon exit for deeper analysis.
- Resource Monitor: Detailed sorting by CPU Time, Threads, RAM, VRAM (GPU Memory), and Disk I/O.
- Security Scanner: Built-in heuristic detection for:
- Hidden Miners: Checks specific paths (AppData/Temp) for disguised malware.
- Fake System Processes: Detects fake
svchost.exe,csrss.exe, etc., running from wrong directories. - Hidden Consoles: Identifies suspicious CMD/PowerShell windows running in the background.
- Interrupts Per Core: Visualizes interrupt load distribution across CPU cores to detect "Core 0" bottlenecks.
- Global I/O: Monitors total Internet bandwidth and Disk usage percentage.
- Memory Insight: Tracks Page Faults, Available RAM, and Standby Cache.
- Disk Diagnostics: Monitors Queue Length and Response Time for NVMe/SSD/HDD.
- Timer Resolution: Displays the current Windows Timer Resolution (e.g., 0.5ms or 15.6ms).
- Mouse Polling Rate: Real-time Hz calculation using Raw Input.
- System Tweaks Check:
- MPO (Multi-Plane Overlay): Detects if MPO is Enabled/Disabled.
- HAGS: Checks Hardware Accelerated GPU Scheduling status.
- HPET: Verifies if High Precision Event Timer is forced.
- TSC Invariant: Checks CPU timer stability.
- Deep Audit: Scans multiple startup locations often missed by Task Manager:
- Startup Folders (User/Common).
- Registry Keys (Run/RunOnce for HKLM & HKCU).
- Task Scheduler: Detects hidden tasks often used by malware.
- Non-System Services: Lists active third-party services.
- Version: 1.5
- Language: C# (.NET Framework 4.8)
- Core Tech: ETW (KernelTraceControl), P/Invoke (NtQuerySystemInformation), PerformanceCounters.

To access Kernel Tracing (DPC/ISR), Pagefile Info, and Security Scans, ALPA must be launched with Administrator Privileges.
- The application automatically creates a scheduled task (
ALPA_AutoRun) to launch with highest privileges on logon if needed.
- Launch: Run
ALPA.exeas Administrator. - Calibration: Wait for
[OK] ALPA Engine LIVEin the Console tab. - Gaming Test: Keep ALPA running in the background while playing.
- Analyze:
- Go to Drivers (ALL) to see which driver has the highest
Max (us). - Go to Performance to check if one CPU core is overloaded with Interrupts.
- Check ALPA_Log.txt or the CSV report after closing for a summary of lag spikes.
- Go to Drivers (ALL) to see which driver has the highest
