Why would shuffling the rays around help with occupancy? I 'd also guess that worse locality could easily obliterate any other benefits, but you never know unle

  I'm working off the hypothesis in the article: > I wonder if RT work is a lot less predictable than rasterization workloads, making workload distribution harder. For example, some rays might hit a matte, opaque surface and terminate early. If one shader engine casts a batch of rays that all terminate early, it could end up with a lot less work even if it’s given the same number of rays to start with.

    You would end up with shader engines working for longer on average but with more "dead lanes" then, with no real benefit, right? Sounds like more flexible scheduling would ultimately be needed.
