The gtx 690 is as you may know a dual-gpu card, and some new games are having trouble with SLI. I finnaly managed to get Far Cry 4 running okay, but then I bought a second monitor and the game is running really badly. It says that it is 80fps but if feels more like 20.
Anyone know what the problem might be?

Both monitors should be 60hz. one is connected with a mini-displayport to hdmi cable, and the other is connected with a DVI-D to hdmi

My pc specs:
1: Gainward Gtx 690
2: i7 3820k
3: 8 gigabyte ram
not sure what motherboard, probably som kind of standard for Alienware Aurora R4
