Weird behaviour... GPU faster than CPU when it should not...

[Dade]

Thanks, it looks good, this fix may also have some unexpected implication like fixing the light tracing brightness variation on animations has been reported few times: light tracing is normalized by the total count of photons traced and if the total is wrong, the total brightness will be wrong too.

P.S. for other readers, jut keep in mind we are talking of CPUs with 64 threads or more, don't expect this kind of speed up on an 8 cores

Can blendluxcore 2.3 beta1 be recompiled to include this fix so it easier for render farm to isntall the new build ?

We should release v2.3beta2 very soon.

Light traced caustics still not constant

My 32 thread 3950x actually went from ~3:40 to ~2:30 so big improvements even with half the threads
