Ray tracing is notoriously heavy on hardware. This release includes several back-end optimizations to the ray-marching algorithm. Users on mid-range hardware will notice slightly more stable frame times, especially in complex scenes with multiple light sources. The shader is now more efficient at discarding rays that don't contribute to the final image, saving precious GPU cycles. Better Compatibility with Reshade 5.x+
If you’ve never tried RTGI, this is the version to start with. If you’re a veteran, update for the stability and slightly faster frame times. And always, always pair it with a good ambient occlusion shader (like MXAO) for dark corners that screen-space rays miss. rtgi 0.17.0.2 release
Some users have reported that the new Hybrid Roughness mode can cause slight oversaturation in very dark scenes. The developer has acknowledged this and suggests lowering the Indirect Lighting Boost slider from 1.0 to 0.85 for a more natural look. Ray tracing is notoriously heavy on hardware
Light now interacts more realistically with different material types. The update refines the way light scatters on rough versus smooth surfaces. You will notice that metallic objects have a more distinct "sheen" from indirect light sources, while matte surfaces like cloth or stone absorb and diffuse light with greater accuracy.
