Pascal Gilcher has moved on to (version 2.0), which uses Machine Learning (ML) denoising. It is incredible, but it requires an NVIDIA RTX 2060 or better to run at 1440p.
The defining feature of the RTGI 0.33 exclusive update is its advanced use of . By comparing geometric changes from the previous frame directly to the current frame, the shader accurately tracks how pixels move across the screen. This drastically mitigates the "shimmering" artifacts common in older screen-space implementations, ensuring that lighting remains locked to geometry even during fast camera pans.

Because RTGI is a sophisticated, ongoing project, the latest versions are typically exclusive to Pascal Gilcher’s community supporters. Join the Patreon:

The Democratization of Global Illumination: An Analysis of ReShade Ray Tracing Shader RTGI v0.33
The exclusive 0.33 gives you sliders that did not exist before. Here is the Goldilocks configuration for that "RTX On" look without the "PPT Slideshow" framerate.
In the fast-evolving world of PC gaming, the pursuit of photorealism is constant. While modern gaming engines increasingly support native ray tracing, many beloved titles—both old and new—suffer from dated, static lighting, or expensive, performance-heavy, official implementations. Enter , a post-processing injector that has revolutionized visual enhancement. By comparing geometric changes from the previous frame
When a light source hits an object in a vanilla engine, the surrounding surfaces typically remain flat and unaffected unless the game uses expensive pre-baked lightmaps. RTGI forces light to physically "bounce" off surfaces. For example, if your character stands next to a bright red wall, the light hitting that wall bounces a subtle crimson hue onto the character’s armor and the surrounding floor tiles.
Among these, the release remains a significant milestone in the evolution of these shaders, offering advanced features that fundamentally improved the quality, stability, and performance of on-the-fly global illumination. What is RTGI 0.33?
