RTGI ReShade Shader Releases New Version Optimizes Screen Performance

Pascal Gilcher, known as "Marty McFly", has been six months since he released an update for his popular RTGI ReShade shader.However, he just launched a major new version to Patreon subscribers.

The MOD developer tried to implement the ReSTIR GI algorithm in shaders, but encountered several limitations, such as chromaticity noise (because reservoir sampling can only retain light in a single direction), sample correlation that destroys the denoiser variance estimate, and white noise output.Eventually, Gilcher decided to design his own sampling algorithm, which he believed was far superior to ReSTIR GI in quality.The reflection effect of RTGI shaders has also been significantly improved, and the pixel-level precise paths are now tracked using HiZ Min-Max Tracing technology.

The developer also shared a future plan: split the diffuse and specular components of RTGI into standalone shaders for easier management.

Gilcher's other shaders have also been improved, such as MXAO fixes the low-radius halo issue around objects, especially Launchpad, whose optical flow is used by multiple other shaders.This new version of Launchpad introduces an innovative gradient descent-based algorithm that handles subpixel offsets more efficiently than traditional grid-based search methods.

Users can now choose from two general gradient descent optimizers:

- Newton: Convergence is fast, and it is more suitable for lower quality settings.

- SophiaG: Convergence is slow, but better minimum values ​​can be found, suitable for high-quality settings.

Finally, Gilcher released a brand new shader: path traced volumetric fog.It was originally built as a ground-based reference for real-time effects, but developers ended up enjoying it very much, so the full path-tracking version is now in the beta phase, though it is currently only used for screenshots.Please check out the examples captured below in God of War.

Path Tracking Volume Fog Shader is currently only available in Patreon's highest subscription hierarchy "Photon Mappers" for $20 per month.
