Asdf Overlay: Blazing Fast Windows Overlay Library

Asdf Overlay is a blazingly fast and easy-to-use Windows overlay library that draws on top of the window framebuffer by hooking rendering backends. It utilizes GPU shared textures to avoid CPU framebuffer copies, enabling rendering of overlays of any size without performance loss. Supporting OpenGL, DX9-DX12, and Vulkan, it offers features like input capture control. Already used in projects like ingame lyrics overlays and ingame overlays, it requires Node.js, pnpm, a specific Rust compiler version, and MSVC.
