AHH, i get the same thing on a gtx470, if i've watched a video since reboot the fps drops to really low levels, its the difference between 10 and 60. 296.10 does not do it, but 301.24 and .42 both do it.
For the record. I spend a good few hours going through this so I'll spill my info for those so you don't have to.. I still haven't found a fix.

I have tried drivers:
275.33, 285.38, 285.79, 296.10, 301.10, 301.42, and I'm now on 304.79.
I only get stutters in Multiplayer.
I see alot of cpu activity running bf3. alot. almost peak on all 4 cores.
So I'm narrowing down possibilities.
I've tried every in game rendering code as well as every suggested combination of settings. I updated bios for motherboard and all drivers. I'm also on an ssd. I have played this before flawlessly with my system and all of a sudden I'm getting the stutters when I reinstalled the game to play it. ..... Bullshit.
Stuttering every 3 steps. And mouse lag as well if you are in a tank or something hard to lock on when it moves after you do. Ruins Battlefield 3 for now.
I hit http://www.speakeasy.net and gave my connection here in the studio a speed test.
I'm limited to 1.4 mbps down. and my up is higher. So I'm thinking this is where the problem may be, and possibly being worse as others are on the network. I only achieve 5.0 mbps right next to the hub on my mbpro. I'll be getting a brand new ethernet patch to see if I can get rid of the stutter and hoping its from intermittent lag due to bottle neck in the cable. (It has to be older Cat5)
