I would like your comment to a quick test I made here
http://forum.1cpublishing.eu/showthread.php?t=22665
I experimented various setting how u'll see, I wonder why (from medium settings to high, tested also forest=0) I have near to zero fps improvement.
Is the bottleneck elsewhere?
In this test cpu usage: Cpu1 mostly 70% Cpu 2-3-4- 40-45% more or less
Ram usage 75% more or less
VRam 95-98%
very strange 4me
Cheers
