Working on a PC build to handle 12 outputs and ran into something odd. Just testing for now using R5 Arena demo install, on Windows 10 Pro with 3 GTX 980s. With nothing actually playing, on startup, I have 35-40 FPS. Playing videos starts a slow decrease in FPS, which I would expect. What is odd is when I disable and re-enable the global effects setting, again with nothing running, I usually get the system to run at 60 FPS. I've also noticed it jumps up to 60 and stays there when I open and close GPUZ to see what the load is.
Any thoughts on where to look for a fix? Should I be seeing 40 FPS when nothing is playing?
