660 GTX SLI problem

post #1 of 4
Thread Starter 
everytime i run a game, it will be at 60 fps but then drop to 30 fps for a while then go back up to 60 fps.

its happened on batman AC, bf3, red faction Armageddon and even rayman legends once.

i have no experience with SLI so i have no idea whats going on with this.

Try turning off Vsync. The other day when I was playing Crysis 2, my game seems to be locked on only 25 or 50 fps exactly. Turning of Vsync seemed to get rid of the problem.
