Reshade Ray Tracing Shader Rtgi 0.33 Jun 2026

RTGI is not free; it requires significant GPU power. However, 0.33 is designed to be as efficient as possible.

Understanding the internal slider settings will allow you to balance high visual fidelity with playable performance. Ray Length Controls how far a cast ray travels before expiring.

The headline feature is the vastly improved spatial-temporal denoiser. The grainy "fireflies" in the shadows are almost entirely gone. The image stabilizes much faster when you stop moving, and the ghosting behind fast-moving objects (like dragons in Skyrim or cars in GTA V ) has been drastically reduced.
