One of the primary concerns with any graphics enhancement is performance impact. RTGI 0.33 is designed to be relatively lightweight, with a performance impact that's manageable on modern hardware. However, it's essential to note that the shader's performance will vary depending on factors like system specifications, game complexity, and settings.
Launch the ReShade installer and select your game's executable ( .exe ).
RTGI 0.33 functions across multiple graphics APIs, including DirectX 9, 11, 12, OpenGL, and Vulkan. This enables gamers to add cutting-edge lighting to retro titles like Unreal Tournament or Max Payne as easily as modern games.

Run the setup and select your game file.
If an object is not actively visible on your screen, it does not exist in the depth buffer. Therefore, a bright neon sign directly behind your camera will not cast light into the room in front of you until you turn around to look at it. One of the primary concerns with any graphics
Visual impact
Conclusion RTGI 0.33 is a powerful ReShade shader offering a practical balance between visual improvement and performance cost. It’s most effective in static or slowly changing scenes where temporal accumulation can remove noise, and when properly tuned to the target hardware and game. Expect screen-space artifacts and simplified lighting behavior compared with true hardware ray tracing, but significant aesthetic gains for many titles.

Controls how many rays are cast per pixel. Set to 3 or 4 for gameplay; reserve 7 or 8 exclusively for screenshot photography.
A major addition in 0.33 is the utilization of motion vectors, which significantly improves the temporal stability of the lighting.
Ray Traced Global Illumination (RTGI) shader, developed by Pascal Gilcher (Marty McFly), is a sophisticated post-processing effect for ReShade that simulates real-time global illumination and ambient occlusion in almost any game. Unlike native ray tracing, it operates in screen space by tracing rays against the game's depth buffer, making it compatible with non-RTX GPUs. Key Features of RTGI 0.33
