Unlike native ray tracing (e.g., Cyberpunk 2077’s RT or NVIDIA RTX), RTGI does know whether a surface is wet, rough, metallic, or translucent. It assumes all surfaces behave similarly. Some users have noted that RTGI can darken corners too much or brighten areas that should remain shadowed. The effect is a lighting approximation , not a physically accurate simulation.
Navigate to your game’s installation directory where the game .exe resides. Open the reshade-shaders folder.
Controls the accuracy of the lighting. Setting this to 3 or 4 provides excellent performance, while 7 or 8 offers maximum visual quality at a steep hardware cost. Lighting and Blending
Enable this to generate micro-shadows under characters' feet, small pebbles, and foliage, removing the "floating" look common in older games. Performance Tweaks Reshade Rtgi 0.36.1
The shader includes sliders that allow each user to decide the balance between quality and frame rate. You can adjust:
Locate the Shaders and Textures directories inside the zip file.
0.36.1 optimizes how the shader uses the scene’s environment map to calculate ambient lighting, resulting in more realistic shadows and light bounce. How RTGI 0.36.1 Transforms Games Unlike native ray tracing (e
Copy and paste the RTGI shader files into reshade-shaders/Shaders and the texture files into reshade-shaders/Textures . Step 3: Configure the Depth Buffer
It adds "color bleeding," where light hitting a colored object (like a red wall) naturally reflects that color onto surrounding surfaces. How to Install Reshade RTGI 0.36.1
The algorithm operates as follows:
A: Yes, but with caution. Using RTGI after DLSS (as a post-process) works fine. Using RTGI before upscaling will denoise the ray tracing, then the upscaler will re-introduce artifacts.
ReShade RTGI is a post-processing shader, developed by Marty McFly, that injects ray-traced global illumination into almost any game running on DirectX 9, 10, 11, 12, OpenGL, or Vulkan. Unlike native RTX, which requires specialized hardware and game developer implementation, RTGI works on a wider range of GPUs by utilizing screen-space data and depth buffers.
is a post-processing shader injection framework. It simulates how light bounces off surfaces within a game scene. The effect is a lighting approximation , not
