Specular RTGI! Extended my RTGI to support specular as well as diffuse. Spec and Diff rays are shot from a shared fixed ray pool, the rays are dynamically distributed across the screen based on demand. Perf impact over diffuse-only is around 25%. Am very happy with the result.

Bsky tends to remove noise from videos but i think its still visible here. A comparison of the temporal accumulation only (spatial passes disabled here for visualization purpose). Ray Redistribution On vs Off. Same performance, much better resolve with redistribution.

Adaptive ray rate per pixel! A series of compute passes distribute a fixed budget of rays over the pixels on the screen, a fixed trace dispatch goes over the final ray list and traces them. Improves disocclusions drastically. Allows way fewer (i'm using 2x fewer) rays per pixel at BETTER quality.

Testing in many different settings is very important for graphics techniques. What works in one setting will fall apart horribly in another. Usually its best to have actual game data to work with. At home i use a lot of dumb test scenes. Very happy to say the GI now works well in all of them 🥳
