Present Hook

Present Hook

Intercepting the graphics present/swap path (e.g. IDXGISwapChain::Present, DX9 Present/EndScene, wglSwapBuffers, vkQueuePresentKHR) to draw overlays or copy frames each frame.

Uses

Internal ESP/menus (often Dear ImGui), wallhack/chams via draw/shader hooks, OBS Game Capture–style backbuffer sharing for streaming or AI visual pipelines.

Detection surface

VTable/code integrity on Present, call-stack analysis, known hook DLLs (obs-graphics-hook64.dll), staging-texture / GPU→CPU readback at frame rate. AC screenshot paths may also hook Present or DXGI Desktop Duplication.
