Performance Tip: Keep this between . Higher values cause massive performance drops in wide-open, outdoor environments.
What if you could bring cinematic, path-traced ambient occlusion and indirect lighting to decades-old classics, indie games, or even your favorite competitive shooters? Enter the .
Go to the "DX11/DX12/Vulkan" tab in ReShade and ensure the correct depth buffer is checked. If your depth buffer is inverted or broken, look for the Edit Global Preprocessor Definitions button on the Home tab and toggle RESHADE_DEPTH_IS_REVERSED between 0 and 1. reshade ray tracing shader rtgi 033
While 033 was a stable and beloved version, the RTGI shader has not stood still. Its developer, Pascal Gilcher, is continuously innovating. In a massive update after 033, he attempted to use NVIDIA's advanced ReSTIR GI algorithm but ran into issues like color noise. Undeterred, he , which he claims provides superior quality and stability. Newer versions also feature HiZ (Hierarchical-Z) Min-Max Tracing for pixel-perfect reflections and, most recently, a fully path-traced volumetric fog shader, pushing the boundaries of what's possible with a screen-space injector.
The most significant addition to 0.33 is the use of motion vectors. This allows the shader to track pixel movement between frames, significantly reducing the "ghosting" or "smearing" often associated with temporal denoisers in previous versions. Performance Tip: Keep this between
This controls how far each ray travels to look for geometric intersections. Lowering this value improves performance but might cause light leaking through thin walls. Find a sweet spot around 10 to 14 steps.
One RTGI 0.33‑specific tip: use resolution if you are struggling with low frame rates. The quality difference is subtle in motion, but the performance gain can be dramatic. Enter the
This article serves as a comprehensive guide to RTGI 0.33, explaining what it is, why version 0.33 remains a significant milestone, and how to master its installation, configuration, and optimization.
If you are running games at 4K or 1440p, using in-game upscalers like DLSS, FSR, or XeSS alongside RTGI 0.33 will help offset the post-processing performance hit. Conclusion
RTGI solves this by calculating how light bounces around a scene in real-time. It simulates how light behaves in the real world: colors bleed onto nearby surfaces (color bleeding), shadows become softer and more realistic the further they get from the object (contact hardening shadows), and ambient light feels natural rather than flat.
