Something weird is going on, when I go to campaign mode the intro screens stutter through and the sound loops back, and my motherboard horn goes off after a while in the main menu, like my cpu is overheating, but my cpu is above spec, it's a Core 2 Duo E7500 @ 2.93 & 2.13GHz. According to EVGA Precision my graphics card is hardly even being used, and I just updated my graphics and sound drivers. I do have a sound card.
Help?
Yea, that happened to me too, I messed around with the audio settings and turning off the second option (sound ambient? Something like that), fixed it for me. I'm running a Core 2 Duo at 2.9GHz and a Radeon 5570 with 4GB of RAM on Windows 7 Home Premium 32-Bit. Runs smoothly at the preset High settings and 1360x768 Resolution. Only chokes during lots of smoke.
Expect lots of patches/updated drivers to be released in the next couple of weeks.
I also get TONS of lag on 64 player maps, but not on 32. Which I don't mind. I bet they'll fix it sooner or later. And it's not just me either, a couple of other guys were complaining about it too.
But all in all, one word describes BF3.....
