Hi. A bit more info regarding the problems with rendertimes and noisecalculation I mentioned in my previous post.
The scene used is lit by an HDRI (exr) and contains 1 tree-object placed on a ShadowCather-plane. I haven't found the culprit, but here's my findings so far (all done with DB April 23 2019, with a 5% noise limit):
1) Setup: HQ filtering, no denoise
Estimated time - 1min 3 sec
Noise calculated (after 5 passes) - 8,26%
Actual rendertime - 2min 16sec
Final noise-level - 4,79%
Passes total - 15
2) Setup: HQ filtering, HQ denoise
Estimated time - 10min 24sec
Noise calculated (after 5 passes) - 24,70%
Actual rendertime - 28min 20sec
Final noise-level - 4,90%
Passes total - 110
3) Setup: normal filtering, no denoise
Estimated time - 46sec
Noise calculated (after 5 passes) - 7,17%
Actual rendertime - 1min 12sec
Final noise-level - 3,57%
Passes total - 10
4) Setup: normal filtering, HQ denoise
Estimated time - 8min 32sec
Noise calculated (after 5 passes) - 21,06%
Actual rendertime - 6min 03sec
Final noise-level - 4,90%
Passes total - 30
I never noticed this behavior before, and honestly thinks this is a bug. After theese findings in DB, I rolled back to v3,1 but things didn't change - even after a uninstall/reinstall :(
Does anybody here have similar experiences or explanations?
Regards
