A high-velocity, native C++ co-op engine for The Witcher 3 (DX12). Built for zero-bloat performance and high-fidelity state synchronization.

"When the co-op logic is so atomic, even Geralt can't tell who's the original."

WitcherSeamless v0.1.0-alpha

⚡ Architectural Pillars

• Zero-Jank Input: Event-driven WH_GETMESSAGE hooks bypass the standard engine polling for instant UI response.
• Midnight UI: A premium, semi-transparent dashboard primitive (Alt+S) built with custom O(height) line-fill rendering.
• Atomic Sync: Narrative facts and quest states are synchronized via a failure-resistant atomic protocol.
• Dead-Reckoning: High-frequency world-space interpolation ensuring 60fps smooth player movement even under network jitter.

🎮 Feature Set
