RTGI 0.33 is a specific build of the shader that offered significant performance optimizations and stability improvements over earlier builds. It uses screen-space data to calculate how light should bounce between surfaces, creating realistic indirect lighting, color bleeding, and soft shadows. This adds depth and atmosphere to games that rely on static, flat lighting.
RTGI 0.33 is computationally heavy. Even "patched" versions will significantly impact your FPS (often 10-20% loss depending on settings). It requires a dedicated GPU; integrated graphics cards generally cannot handle the workload. reshade rtgi 033 download patched
