We will have to wait and see. With “perfect” reflections, yeah there’s an assumption that with very glossy materials, any distortion or low poly look will be extra noticable. Reflections might use lower LOD versions of models, or that might be unnecessary optimization. There’s still a lot of embargoes and such little access to the hardware, it’s very hard to speculate.
I’m curious what’s going to make a bigger impact, RTXAO or RTXReflections. And how expensive they are going to be separately and together. Also really excited about possible RTX lightmass, and that AI AA.
