Enable the DisplayDepth shader. Your screen should show a clear grey/white depth map. If it’s solid black or flickering, RTGI will not work.
[Standard Game Lighting] ---> Flat shadows, uniform ambient light, no color bleeding [ReShade RTGI 0.33] ---> Dynamic color bleeding, accurate contact shadows, realistic bounce light Color Bleeding
Although RTGI has since moved to newer versions (0.36, 0.51 etc.), v0.33 remains a beloved stable release – reliable, well‑documented, and the version that many classic preset files still expect. reshade ray tracing shader rtgi 033 2021
Extract the qUINT shader files (including qUINT_RTGI.fx ) into the reshade-shaders/Shaders folder.
Traditional video game graphics utilize pre-baked lighting maps or screen-space ambient occlusion (SSAO) to simulate depth and shadow. While fast, these methods cannot calculate true indirect lighting—such as a bright red wall casting a warm pink glow onto a white marble floor. How RTGI Works Enable the DisplayDepth shader
In 2021, the ReShade RTGI (Ray Traced Global Illumination) shader, developed by Pascal Gilcher (Marty McFly), was a transformative post-processing tool that brought advanced lighting effects to games without native ray tracing support. Version
Here is a comprehensive breakdown of what made the 2021 RTGI 0.33 release a game-changer, how it works, and how you can configure it for optimal visuals. What is ReShade RTGI 0.33? [Standard Game Lighting] ---> Flat shadows, uniform ambient
