I am getting a solid FPS in BF3 (minimum is 35) with my system, but very often the game would freeze for a fraction of a second. In the skies (with jets) I get 60 FPS. But that freezing problem ruins the experience.
^ nice catch. Yeah you can't use DDR3 on a Core2 system. They use DDR2. Also, you will want to make sure that you have a 64 bit version of windows to support more than 4GB of RAM.
I think you may be hitting a RAM limit in your game. If it is using the page file it might cause the game to stutter while playing. BF3 requires at least Windows Vista to play and that or Windows 7 along needs about 2GB to run efficiently.
Umm alright, some clarification. My mobo has both DDR2 slots and DDR3 slots, though it's not possible to use both simultaneously. I already ran 8GB of DDR3 on that mobo, just for testing (it wasn't my RAM so I don't have it anymore). Also, I am already running a 64 bit version of Windows 7.
I also get the same stuttering even with more then solid fps as do many many other people using both Nvidia and AMD graphics
I have not seen one true fix however it seems to be a well known problem

I too have this stutter problem every few seconds in Battlefield 3.
If I stand still I can mouselook around perfectly smooth, the stutter only occurs while moving. The effect is magnified the faster I move i.e. in a vehicle.
I can even see the spinning radar dish animations stutter every few seconds.
I've tried countless rumoured fixes and resintalled Windows a couple of times to no effect.
I got two games since October 28th where it didnt stutter, once after I manually setup a pagefile in Windows, and once after I manually updated Punkbuster, in each case the problem rapidly returned and those steps never worked again...
