Running vsync, I spent hours trying everything, finally ipulled it out and 're seated it and back to normal!!! All I can think is it's such a big heavy card it must have dropped a bit. Still can't use mantle with vsync though, not sure what's going on there.Are you using v-sync drovers? I'm running a 2700k and 2x 7970 and at 1080 on win 8.1 overclocked to 1100/1575 I'm buttery smooth. I'll still tip to 55 on odd occasion but most of the time I'm 100+. I have motion blur, and in game AA turned off mind. My 2700k runs at 4.6. What have you got your 3770k running at?? I'm on the 14.1 cats as well
