Thanks for the link. I was trying to figure out if re-writing code using ray sorting is worth the effort in the case of everything fitting in main memory.
For out of core rendering, it seems to be the case.

It seems to make sense for out of core rendering, it's not clear if, for cases where everything fits in memory, increased cache coherence would still increase performance in a sensible way.
Hi guys, Anybody has some experience with ray sorting on CPU based path tracers? I'm working on a CPU-only path tracer/bidirectional path tracer based on Embree. I was thinking about implementing ray reordering and packet tracing for incoherent rays to increase performance (since Embree supports pac...
