Arnold- GPU 11 hours on a Titan 12 GB
Yes a lot of flicker..not usable. It was 16 hours on a dual Xeon. Next to add my 1070 card to see if Arnold plays well with 2 mismatched cards. I was a bit naughty..I used Arnold Noise reduction on a GPU animation when that should be strictly sued for CPU renders. But I seem to have gotten away with it. I chose this model because it has a lot for the Anti Aliasing to do and plenty for the Brute Force GI to tackle.
