ReShade RTGI | Ray Traced Global Illumination - marty's mods
| Feature | What It Does | |---------|---------------| | | Models both the soft bounce of diffuse light and the sharp reflection of specular light, something most classic games lack. | | Screen‑Space Ray Tracing | Uses the game’s colour buffer and depth information to trace rays in 2D screen space, thus working on any GPU (Intel HD, AMD, old NVIDIA cards). | | Temporal Stability | New sampling in v0.33 reduces the flicker and “crawling” artefacts that plagued earlier RTGI builds. | | Performance / Quality Scalability | Sliders for “Number of Rays” and “Number of Steps” let you dial in exactly how much performance you sacrifice for lighting accuracy. | | Ambient Occlusion First | By default RTGI adds a contact‑shadowing layer that looks similar to HBAO+, then builds full bounce lighting on top of it. | | Wide Compatibility | Works with virtually any game that provides a readable depth buffer – including DX9 titles, Unity games, OpenGL simulators, etc.. | reshade ray tracing shader rtgi 033 2021
The functions by intercepting the game's depth buffer (the data map showing how close or far geometry is from the camera). It casts thousands of virtual light rays across this screen-space data to accurately compute Diffuse Global Illumination and ambient contact shadows in real-time.
