Reshade Ray Tracing Shader Rtgi 0.33

: Uses the screen's depth information to calculate light occlusion, providing a much higher level of detail than standard screen-space ambient occlusion (SSAO). Installation & Setup Requirements

RTGI (Ray Traced Global Illumination) is a post-processing shader that uses the of a game to simulate how light bounces off surfaces. Unlike hardware-native ray tracing (like NVIDIA RTX), RTGI works on almost any modern GPU by calculating lighting based on what is visible on your screen (screen-space). Key Features of Version 0.33: Reshade Ray Tracing shader RTGI 0.33

The shader, developed by Pascal Gilcher (widely known as Marty McFly ), is a major update that brings real-time, screen-space ray-traced global illumination to older and modern PC games. By physically simulating how light reflects off in-game surfaces, it bridges the gap between traditional rasterized lighting and true hardware ray tracing. : Uses the screen's depth information to calculate

By injecting real-time ray-traced shadows and light bounces, RTGI 0.33 adds "depth" to flat scenes. For example, in a game like GTA V , light hitting a bright red floor will subtly bounce a red tint onto the surrounding walls and ceiling, a phenomenon known as "color bleeding".

Marty McFly has since moved on to (currently in Patreon beta) which uses "ReSTIR GI" — similar to what NVIDIA uses in its developer SDKs. Furthermore, Reshade 6.0 now includes a native "Depth3D+" system that conflicts with older RTGI builds.
