ReShade Ray Tracing Shader RTGI 0.33 Exclusive: A Game-Changer for Visual Fidelity

The , created by Pascal Gilcher (also known as Marty McFly), is a highly advanced screen-space ray tracing tool that adds dynamic global illumination (GI) and ambient occlusion (AO) to almost any 3D game. While RTGI has since moved to newer versions like 0.70, version 0.33 remains a landmark release for its specific feature set and widespread adoption in various mod presets. Core Features of RTGI 0.33

Drop the RTGI .fx file into the reshade-shaders/Shaders folder.

ReShade is a universal post-processing injector for games. Pascal Gilcher (McFly) developed the RTGI shader to simulate real-time ray-traced lighting within ReShade.

It was optimized to run more efficiently on a wider range of hardware, though it still remains heavy on GPU resources. Enhanced Compatibility:

This version was famously distributed as an "Alpha/Beta" exclusive for supporters on Pascal Gilcher's Patreon .

Screen-space ray tracing has revolutionized PC gaming graphics. Marty McFly’s (Pascal Gilcher) shader for ReShade stands at the forefront of this revolution. The highly sought-after RTGI 0.33 exclusive release introduces unprecedented lighting accuracy to older and modern titles alike. What is ReShade RTGI 0.33?

At its core, RTGI is a post-processing injector—a filter that sits on top of a running game—that aims to mimic the behavior of light in the real world. Developed by the legendary modder Pascal "Marty McFly" Gilcher, it has become the gold standard for post-process ray tracing.

global illumination, allowing light to bounce off surfaces and realistically illuminate surrounding areas. Hardware Independence

You do not need an RTX graphics card. The shader does not use RT cores. It uses compute shaders and runs on any GPU that supports DirectX 10.1 or higher. Users with a GTX 1060 or RX 570 can expect a playable experience with careful settings.
