Reshade Ray Tracing Shader Rtgi 033 May 2026

Ray-Traced Global Illumination (RTGI) simulates how light bounces off surfaces to illuminate areas not directly hit by a primary light source.

: It adds realistic shadow casting and material interactions that bridge the gap between real-time gaming and pre-rendered visuals. reshade ray tracing shader rtgi 033

The 0.33 update was a major milestone for the shader's development: Ray-Traced Global Illumination - GitHub Pages This means it can only "trace" what is

: Unlike "true" hardware-based ray tracing, this shader operates on depth buffer information . This means it can only "trace" what is currently visible on your screen, acting as a highly advanced form of ambient occlusion. Version 0

: Because it relies on the depth buffer rather than specialized hardware, it works on almost any GPU, including older non-RTX cards. Key Features of Version 0.33

The , created by Pascal Gilcher (popularly known as Marty McFly), is a post-processing tool designed to bring advanced lighting techniques—specifically Ray-Traced Global Illumination—to games that do not natively support them. Version 0.33, released as a significant update in August 2022, introduced key enhancements such as motion vectors to improve temporal stability and overall image quality. What is RTGI?
