Red_Eagle_LXIX: Nope, I got a performance downgrade as the game flickers like a strobe light with SLI enabled now for me.
GTX 760s on 352.86 (the latest and one released specifically for this game)
Had to disable SLI for now.
Zanderat: I have have two GTX 760's in SLI and they seem to be running fine. Not seeing this issue.
Not sure what was causing it, but it has stopped doing it ever since I tried recording the game with OBS. Gremlins or a ghost in the machine. :)
And I found out what fixed it.
Borderless = no flicker
Fullscreen = flicker.
The gremlins that fixed it was the oft mentioned bug about the game not saving the fullscreen setting and reverting back to borderless.
Fullscreen I still get the flicker with SLI
