To help tailor this guide further, let me know you are trying to mod with RTGI 0.36.1, your graphics card model , and whether you are experiencing any specific graphical bugs like flickering or missing depth maps. Share public link
: It adds subtle ambient occlusion, filling in the soft shadows where objects meet. Color Bleeding
RTGI is a post-processing shader that injects path-traced global illumination into games via the ReShade framework. Unlike native hardware ray tracing (RTX), which requires specialized RT cores, RTGI calculates lighting using the game's depth buffer. How it Works
Increasing roughness spreads the bounced light softly across floors and walls, eliminating harsh, unrealistic glares. Performance Tuning & Troubleshooting
The 0.36.1 update is not isolated to the RTGI effect alone. Gilcher’s suite of supporting shaders received crucial upgrades:
RTGI 0.36.1 is a specific build of the popular screen‑space ray traced global illumination shader for ReShade. It was the latest stable release for a considerable time before a major update later redesigned the effect. Consequently, 0.36.1 represents the most polished and stable version of the “classic” RTGI that many users still rely on today.
Even with temporal stabilization, screen‑space flicker can occur around moving objects or where the depth buffer changes abruptly. To minimize artifacts:
Copy the files from the RTGI Shaders folder into your game's reshade-shaders/Shaders directory.
Adjust the slider. Lower values reduce noise but increase ghosting behind moving objects. Find a middle ground around 0.40 . 3. Material Properties
