Above is a screenshot of GPU utilization and the nvidia control panel. I can't seem to find what's wrong. This happens in every other game I play as well; only 2 out of the 4 GPUs are being used at any given time (folding works fine, however). I've reinstalled drivers to no avail. Any clues? Thanks.
EDIT: It seems that part of the problem is the GPUs aren't going into "SLI" mode. The green "multi-GPU" bar in the nvidia control panel is supposed to span both cards, but is only spanning one of them. Any idea how to fix this?
