Emitting rays from pixels to check what they hit.

Tune this parameter to prevent light from "leaking" through thin walls or surfaces. Legacy and Impact on the Modding Community
Screen-space reflections and standard rasterized lighting often fail to capture the true depth of modern video game environments. In 2021, graphics programmer Pascal Gilcher revolutionized PC gaming visuals by releasing version 0.33 of his Screen-Space Ray Traced Global Illumination (RTGI) shader for ReShade. This specific iteration finalized crucial performance optimizations and quality filters, making true path-traced lighting accessible in hundreds of legacy and modern DX11, DX12, and Vulkan titles. reshade ray tracing shader rtgi 033 2021

Elevate Your Visuals: A Deep Dive into ReShade RTGI 0.33 (2021)
A common misconception in 2021 was that RTGI 0.33 was "true" hardware ray tracing like NVIDIA’s RTX. It is not.
Here is a blog post you can use to break down how it works and why it’s a game-changer. Tune this parameter to prevent light from "leaking"
To understand the hype around , compare these typical scenarios (text descriptions of contemporaneous screenshots):
The shader, specifically version 0.33 , was a significant update released in late 2021/early 2022 that introduced motion vectors to improve temporal stability and reduce ghosting.
While RTGI is currently in later versions (as development is ongoing via Patreon), v0.33 was a major "public" or semi-public milestone for several reasons:
At its core, RTGI is a post-processing shader that leverages screen-space data to inject dynamic, realistic lighting into video games. Unlike traditional SSAO or basic shadow mapping, RTGI simulates how light bounces between objects on the screen. It creates a fully dynamic, realistic, and immersive ray-traced lighting experience, effectively bridging the gap between offline-rendered images and real-time solutions.
