Before you can use RTGI, you need the ReShade framework.
: A highly sophisticated spatial-temporal denoiser that removes the "grainy" artifacts common in real-time ray tracing.
After extracting the RTGI archive (often named ReShade_GI_Beta_X.X.X.zip ):
Copy any supporting textures into the reshade-shaders -> Textures folder. 4. Activating RTGI in-Game Launch the game. Press the to open the ReShade menu. Click "Reload" to allow ReShade to detect the new shaders. reshade rtgi 033 download full
: This version introduced better blending and stability, reducing the flickering artifacts common in earlier beta releases. Performance and Hardware Compatibility : Unlike native RTX, this works on
Before diving into the download and installation process, it's essential to understand what ReShade and RTGI are. ReShade is a post-processing injector that can enhance the graphics of games by adding various effects such as depth of field, motion blur, and, notably, global illumination. RTGI, or Real-Time Global Illumination, is one of these effects that significantly improves the lighting and shading of games, making environments look more realistic and immersive.
Tip: To verify your depth buffer is working perfectly, temporarily enable the shader. Your screen should display a clear grayscale depth map of the game world. If it is blank or reversed, adjust the global preprocessor definitions (e.g., changing RESHADE_DEPTH_IS_REVERSED from 0 to 1). Optimizing RTGI 0.33 for Maximum Performance Before you can use RTGI, you need the ReShade framework
: The "full" version of RTGI is notable for being distributed primarily through the creator’s Patreon. This model has sparked discussions within the gaming community regarding the ethics of "paid mods" versus the necessity of funding complex software development. Visual Fidelity vs. Performance
If you are struggling with a complex install, it's recommended to join the Marty McFly Mods Discord for troubleshooting, or check out community-driven modding guides on platforms like Return of Reckoning .
This is a limitation of screen-space ray tracing. The shader can only calculate lighting for objects currently visible on your screen. If an object goes off-screen, its light bounce disappears. Click "Reload" to allow ReShade to detect the new shaders

While RTGI does not require dedicated RT cores (like NVIDIA RTX or AMD RX 6000+ hardware), it is computationally expensive. It runs entirely via compute shaders on your GPU. NVIDIA GTX 1070 / AMD RX 580 Recommended GPU: NVIDIA RTX 2060 / AMD RX 6600 or higher
