I have yet to have anyone explain why for example Mirror's edge catalyst runs at a higher frame rate when non SLI. I have 2 1080gtx in sli with best bridge available until HB is available. Had the same problem with my 2 980 TI. Certain games (even new games) would run better without SLI enabled (farcry 4, COD, Smite). And of course some games would run better. I even used nvidia inspector to go to the specific profiles made for those games to run best in SLI and I still am now turning SLI off to play mirror's edge. Can anyone PLEASE help me. This has been ongoing for years for me.
