Ray Tracing is beyond broken in 4.23

I feel like GPU ray tracing is in a state similar to programmable shaders when shader model 2.0 came along and people were trying lots of things and still figuring out what worked and what didn’t. Like Juan said, current consumer hardware can only trace a couple rays per pixel so novel ways of faking things are needed to make best use of those rays.

This is not about conserving performance though. This is really just about bugs. The issues mentioned aren’t really related to faking things, but rather about ray tracing behaving incorrectly.
