My pc is brand new, I installed a clean win 7 a few days before the game came out. I got my driver from the Nvidia battlefield geforce line so it's good.
My multiplayer works OK but still occasionally the game will freeze and boot me out. The campaign is ridiculous though. I'm at a spot now where I crash pretty much on load from one mission (Operation Guillotine). Unfortunately, I'll probably just have to redo the whole campaign.
Really disappointed at the build quality of the game. Sure the visuals are bar none but the "buggyness" and problems kills the experience. I've looked at a bunch of reads and lots of other players having the same issues.
