— Until next frame, keep tracing.
Low / Medium / High now actually mean something. uses 8 samples per pixel and two bounces — heavy but gorgeous. Low drops to 4 samples and one bounce, perfect for 60+ FPS in most games. Reshade Ray Tracing shader RTGI 0.33
This essay explores the technical achievement and visual impact of the shader, specifically focusing on the advancements seen in version 0.33. The Evolution of Post-Process Lighting: ReShade RTGI 0.33 — Until next frame, keep tracing
Version 0.33 separates Global Illumination (light bounces) from Ambient Occlusion (contact shadows). Low drops to 4 samples and one bounce,

It is crucial to manage expectations regarding performance. RTGI is computationally expensive because it runs on the GPU's generic compute shaders, rather than dedicated RT cores.
