Once RTGI is enabled, open the shader parameters menu at the bottom of the ReShade overlay to fine-tune the look. Ray Length & Ray Quality
: Simulates how light bounces off surfaces to illuminate areas not directly hit by a light source (e.g., a red wall reflecting a subtle red glow onto a nearby floor). reshade ray tracing shader rtgi 033

A bright red block sitting next to a white wall will naturally project a soft red hue onto that wall. This comprehensive guide covers how ReShade RTGI 0
Screen-space ray tracing has revolutionized PC gaming graphics. Pascal Gilcher’s shader for ReShade brings path-traced lighting, ambient occlusion, and physical reflections to almost any 3D game. Version 0.33 introduces critical performance optimizations and image quality adjustments. This comprehensive guide covers how ReShade RTGI 0.33 works, how to install it, and how to optimize your settings for the perfect balance of visual fidelity and framerate. What is ReShade RTGI 0.33?
ReShade RTGI takes a different approach by leveraging . It uses the game’s depth buffer—the data that tells your graphics card how far away objects are from the camera—to cast rays and calculate lighting.
