BioShock Infinite Lag Spikes

Hey,

I got a gtx 560 ti in SLI playing bioshock and I'm having weird, pretty heavy lag spikes (for just a split second) every 10-15 seconds or so. I can still play but it really bothers me.

I'm on the most recent nvidia drivers, I've reinstalled them several times, I've tried playing on all setting in-game, and I've played around with my clock speed but I'm still having these issues...

Has anybody had any similar problems? Any solutions?

Maybe it does not like SLI GPUs? Other than that idk.

I had issues with it too but was enjoying the game far too much to really let it bother me..

I did read that it could be related to VRAM but can't find the exact place I saw it initially..

Google is your friend though, also have a look here.. - http://www.giantbomb.com/forums/bioshock-infinite-6060/pc-stuttering-fix-1430346/
