Reshade Ray Tracing Shader Rtgi 033 2021 ((new)) Jun 2026

Locate your game's directory and find the reshade-shaders folder.

On the subreddit, people posted side-by-sides: before and after screenshots that read like confessions. "Look at the way the light pools," one user wrote. Another posted a short clip where a character lit a cigarette and the ember threw orange halos over the empty room—an almost sacred animation created entirely by the shader’s afterthought of rays. Arguments flared about frame rate drops and flicker; someone shared a script that toggled RTGI only in still screenshots. Kira didn't care about frames per second. She recorded a clip and sent it to her friend Aarav.

: Use the Spatial Filter (Preprocessor Definition: SPATIAL_FILTER=1 ) for a cleaner look at the cost of a small performance hit. ReShade 5.3 and RTGI 0.33 Update | August 2022

Install the latest version of ReShade to the game's executable (e.g., witcher3.exe ). Locate your game's directory and find the reshade-shaders

Select the correct rendering API (DirectX 9, 11, 12, or Vulkan).

You are likely here because you found an old mod guide or a YouTube video from 2021 asking for this specific version. Here is the exact method to get RTGI 0.33 running on your modern system. Another posted a short clip where a character

Optimizing code to lower the massive frame-rate cost associated with screen-space ray tracing. Key Features Introduced and Refined in v0.33 1. Advanced Denoising Infrastructure

Unlike native ray tracing solutions from Nvidia (RTX) or AMD (RX), RTGI 0.33 does not rely on hardware-level BVH (Bounding Volume Hierarchy) traversal. It executes entirely through standard compute shaders. This means you can run ray-traced global illumination on older graphics cards, including the Nvidia GTX 10-series or older AMD Radeon cards. Revolutionary Image Denoising

– While NVIDIA and AMD pushed hardware-accelerated ray tracing in blockbusters like Cyberpunk 2077 and Control , PC gamers with older GPUs or libraries of classic titles were largely left in the dark. Enter Pascal “Marty McFly” Gilcher and version 0.33 of RTGI (ReShade Ray Tracing Global Illumination) – a shader that simulated ray-traced global illumination using only post-processing, no specialized RT cores required.
