Hi everyone, i'm currently fearing the worst right now. I have a High end 2011 27" iMac with 3.4 i7 and 2gb 6970m. Has anyone experienced going into games and occasionally having the fps capped at 30 when it ran at 60 prior? (this is with v-sync obviously) which brings me to my next question. Is everyone who is playing games with a 27" 6970m using v sync? Because the screen tearing on my screen makes it pretty much unplayable. It is so bad. Im fearing I may have a faulty card.
