So i did some tests on a simple bottle render i’ve been using recently. interesting findings…
(all rendered @ 1024 samples with 32x32 tiles)
2.80 gpu + cpu (32x32 tile) - 5:26.70
2.80 cpu (32x32 tile) - 11:22.20
2.81 gpu + cpu (32x32 tile) - 10.56.05
2.81 cpu (32x32 tile) - 11.55.26
So there’s some pretty massive slowdown there!
but when rendering with GPU+CPU on 2.81 my cpu hit 83.9 degrees! Every other render it stayed around 70. Very strange.
Weirdest of all - the renders actually look different despite being from an identical file and settings (with cpu or gpu).
Will post pics tomorrow for comparison…
