New attempt , 400 samples PGI+OIDN, 1.4min/frame.
There are some artefacts from slowing down 50% and blowing up to 3k resolution with DaVinci Resolve.

I guess this is without photonGI?

No, this was rendered with persistent PGI cache, bringing down render time from 6min to 1min 24s so that I could do a longer animation.

Excuse me what?! I did not expect pgi to be so stable

It's computed once and then only re-used. Only works if just the camera is moving.

I see, btw I was today rendering some interior previews that had rendertime faster than preprocessing. We need faster render startup.

We need faster render startup.
opencl compilation is the killer in this case.

If only camera is moving, why compiling openCL kernel each time? Why is kernel compilation not optimized as for view port render? It could save so much time for animations!

I'm pretty sure the kernels are cached and re-used if only the camera is moving.

I‘ll check it this evening.
