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.
