Older versions of screen-space ray tracing suffered from "noise" or graininess because fewer rays were cast to save performance. Version 0.33 utilizes advanced temporal filtering, blending data from previous frames to smooth out lighting artifacts without melting your graphics card. Hardware and Software Requirements
is a premium shader developed by Pascal Gilcher (also known as Marty McFly). It simulates real-time ray-traced global illumination, ambient occlusion, and bounce lighting. Unlike native hardware ray tracing (DXR) which calculates intersections using the game’s actual 3D geometry data, RTGI utilizes the game’s depth buffer to estimate how light rays bounce off surfaces visible on your screen.

stands as a landmark achievement in the history of PC graphics modding. By employing sophisticated screen-space path tracing algorithms, it managed to bring the visual complexity of Global Illumination to titles that were never designed for it. Despite requiring a subscription for the shader files and demanding substantial GPU power, it democratized ray tracing, allowing GTX 1060 users to experience lighting effects that were conceptually similar to those of flagship RTX cards. While later versions and alternative mods have improved performance and accuracy, version 0.33 remains the foundation upon which modern post-process ray tracing is built, and it continues to be the gold standard for a stable, well-documented ray tracing experience in ReShade.
Version 0.33 utilizes an optimized ray-cone tracing method. Instead of casting thin, performance-heavy infinite lines, it casts widening cones. This approach mimics how natural light diffuses, resulting in incredibly smooth shadows and realistic ambient occlusion without requiring thousands of rays per pixel. 2. Improved Temporal Accumulation (Denoising) Older versions of screen-space ray tracing suffered from
Let’s break down what’s new, how it works, and whether it’s worth your GPU’s sweat.
: Because it is an injection-based shader, it can add modern lighting to older titles that were never designed for ray tracing. Key Features of Version 0.33 While newer versions are available on Marty's Mods it requires a capable PC.
Because RTGI 0.33 relies on the depth buffer and complex mathematical calculations, it requires a capable PC.
