The was not just a mod; it was a movement. It proved that with clever coding, real-time global illumination was possible without $1,200 graphics cards or developer support.
Let’s cut through the marketing hype. stands for Ray Traced Global Illumination . In the context of 2021’s version 0.33, this is not the hardware-accelerated ray tracing found in Cyberpunk 2077 (RTX) or Control . Instead, it is a compute shader running entirely within the ReShade post-processing pipeline.
By the time version 0.33 rolled out in late 2021/early 2022, the shader had perfected an approximation of "infinite" light bounces, significantly reducing the "flatness" seen in older game engines. Installation & Access
Set to "Enable" for better light distribution in newer games. reshade ray tracing shader rtgi 033 2021
RTGI 0.3.3 accurately modeled both soft indirect light (diffuse) and reflections of light sources (specular). Why RTGI 0.3.3 Was a Game Changer in 2021
The quest for photorealistic graphics in PC gaming often demands the latest, most expensive hardware. However, a groundbreaking software solution bridges the gap between aging graphics cards and modern visual standards. This solution is Pascal Gilcher’s Ray Traced Global Illumination shader, commonly known as RTGI. Released in its highly refined 0.33 iteration in late 2021, this specific version became a milestone for the PC modding community. It allowed gamers to inject screen-space ray tracing into almost any 3D game without requiring dedicated RT cores.

Run the installer and select your game's executable file (.exe).
Below is a guide for setting up and optimizing this specific version. 1. Requirements & Access : Created by Pascal Gilcher (Marty McFly).

: Controls how far each ray travels. A value between 10 and 15 offers great accuracy without tanking performance. Lighting and Filter Controls
: To use RTGI, you had to subscribe to Pascal Gilcher's Patreon (usually the $5 tier) to obtain the shader file. The v0.33 update was distributed specifically to active patrons at the time. You can only get the official RTGI shader currently by supporting his Patreon at the appropriate tier.
The 0.33 iteration focused on improving the quality of light bounces and the efficiency of the ray casting process. 1. Improved Performance & Ray Tracing Efficiency
