However, as of today, RTGI 0.17.0.2 represents the apex of what real-time post-process shaders can achieve. It narrows the gap between rasterized and path-traced visuals without requiring a $1,600 GPU.

Use RTGI 0.17.0.2 for games that will never get native ray tracing (e.g., Fallout New Vegas, Mass Effect Legendary). Use native RTX for AAA titles designed for it. 9. The Future of Shader-Based Ray Tracing RTGI 0.17.0.2 is likely the last major version in the "screen-space" paradigm. Martino has hinted at a 0.18 branch that will leverage neural radiance caching (similar to Nvidia's ReSTIR). However, as of today, RTGI 0
Expect the community to port this shader to and eventually RenderDoc for offline rendering workflows. 10. Conclusion RTGI 0.17.0.2 is more than a version number; it is a testament to the power of open-source rendering research. For gamers stuck with older hardware or frustrated by the slow adoption of ray tracing in legacy games, this update delivers tangible visual improvements—smoother motion, fewer artifacts, and better performance scaling. Use native RTX for AAA titles designed for it
In standard rasterized games (e.g., Skyrim, GTA V, Fallout 4, or even Elden Ring), shadows are often "hard" and ambient light is faked using ambient occlusion (AO) and pre-baked light maps. RTGI scans the depth buffer and color buffer in real-time, traces rays from the camera’s perspective, and intelligently bounces light off surfaces. The result? Diffuse illumination, color bleeding, and realistic soft shadows that adapt as the camera moves.
