ReShade RTGI 0.36.1 brings true real-time ray-traced global illumination to almost any 3D PC game. Created by developer Pascal Gilcher (Marty McFly), this powerful post-processing shader bypasses the need for official, developer-implemented ray tracing. By injecting path-traced lighting, ambient occlusion, and bounce light directly into a game's depth buffer, RTGI completely transforms aging classics and modern titles alike.
Controls the number of rays cast per pixel. Higher numbers reduce noise but tank your frame rate. Set this to 3 for gameplay, or 5+ for taking screenshots. Lighting & Bounces

Select the correct rendering API for your game (DirectX 9, DirectX 11, DirectX 12, or Vulkan). Reshade Rtgi 0.36.1
: You need ReShade version 5.0 or higher installed on your target game.
The newer versions (from 0.51 onward) bring ray traced , improved sampling, and split diffuse/specular components into separate shaders. However, for users who prefer a battle‑tested version without sudden changes, 0.36.1 remains a safe and capable choice.
: Search for "RTGI" in the ReShade technique list and enable it. You can then adjust settings like Ray Length Amount of Rays Focal Depth to balance visual quality with your frame rate. Pro Tips for the Best Results How To ReShade RTGI - Install and Adjust ReShade RTGI 0
Reduces the "noise" or graininess typical of screen-space effects, producing a cleaner image during fast camera movements.
Are you targeting or high-end photography/screenshots ?
Run the installer and select your game's executable file (.exe). Controls the number of rays cast per pixel
. It simulates how light bounces off surfaces using only the information visible on your screen (depth buffer data). Universal Compatibility
For RTGI to calculate light properly, it must see the game’s 3D depth map.
Simulates realistic light distribution and multi-bounce lighting.
