so do we. and we get the same result.
it’s just how raytracing works, rn. for every pixel that reflects something, every frame a random ray is cast for rough materials and temporally stabilised. casting more rays to gather more of the environment would kill the performance.
make it all shiny, add bumps and grime or lower the specular to get rid of the reflection noise on rough clean materials. that’s how you gotta do it.
