Im currently running a 4x RTX3090 setup for fast rendering.
But I noticed that not all GPUs are utilized, seen from the Taskmanager (see pic on the right)
Also I was testing the same scene on a 2x RTX2070 Super setup, and it would take about the same time.
Of course theres some bvh overhead but still, 4x RTX3090 should be MUCH faster than 2x RTX2070 Super.
Am I missing something ?
Thanks for any Hints!
