Graphics API

Interception and overlay rendering across DirectX, OpenGL, and Vulkan—Present/SwapBuffers hooks, DXGI swap chains, shader/draw interception, screenshot surfaces, and capture pipelines used by both overlays and AI visual cheats.

Key sub-areas

• DirectX: DX9 EndScene/Present; DX11/12 IDXGISwapChain::Present; draw-call hooks
• OpenGL / Vulkan: wglSwapBuffers, vkQueuePresentKHR, custom layers
• Overlays: internal ImGui-on-Present, external layered windows, DWM/Steam/NVIDIA hijacks
• Anti-screenshot: BitBlt / DXGI Desktop Duplication / Present interception vs evasion
• OBS capture: Game Capture injects graphics-hook DLLs—detection-relevant for AC and AI cheats
