Rtgi 0.17.0.2 Release ((full)) Jun 2026

: Improvements to the diffuse global illumination algorithm for more natural light distribution. Enhanced Ambient Occlusion

Photorealistic; virtually zero noise; stunning color bleeding. 40%+ FPS Drop High-end Enthusiast (RTX 4070 and above) rtgi 0.17.0.2 release

The primary focus of RTGI 0.17.0.2 is the optimization of the shader’s internal logic. Pascal Gilcher, the developer behind the project, has addressed several "edge case" bugs that caused visual artifacts in specific lighting conditions. Reduced ghosting on fast-moving objects. Improved light accumulation in dark areas. : Improvements to the diffuse global illumination algorithm

The 2025 update also saw the implementation of "HiZ Min-Max Tracing," a technique that enables pixel-perfect path tracing for reflections. This method utilizes efficient empty space skipping and is rarely implemented correctly outside of AMD’s own implementations, making its presence in a ReShade shader particularly noteworthy. The developer has also announced future plans to "split RTGI's diffuse and specular components into separate shaders" to manage them more easily as the complexity grows. Pascal Gilcher, the developer behind the project, has
