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.
The actual exclusive RTGI 0.33 includes three critical files that are hard to find: reshade ray tracing shader rtgi 033 exclusive
Note on Legality: Pascal Gilcher has since moved on to a paid "Mortens" version that is closed-source. While distributing the old 0.33 exclusive is technically a violation of his Patreon terms, it is widely archived. You can usually find the untouched exclusive zip file by searching Github Pascal Gilcher RTGI 0.33 release or checking the ReShade Discord’s "archived-shaders" channel. The exclusive 0
The FromSoftware engine uses a primitive global illumination system. RTGI adds bounce light into the Catacombs of Carthus, revealing hidden paths naturally. Set "Ray Length" to 0.90 for dungeons. Note on Legality: Pascal Gilcher has since moved
This paper analyzes RTGI 0.33, an exclusive ReShade-based global illumination shader that implements real-time ray-traced global illumination approximations. It examines architecture, algorithms, performance trade-offs, visual quality, integration with rendering pipelines, shader implementation details, optimization strategies, limitations, and future research directions. We provide reproducible experiments, pseudocode, complexity analysis, and suggested improvements to guide shader authors and graphics researchers working with post-processing GI solutions.
