I have the same problem here.. 15 ~ 20 min and crash (Windows out of memory), and close app. Only solved rebooting the system!
My system:
Windows 8.1 Pro x64
Intel i5 3570k
AMD HD 6950 2Gb (Driver 13.11 Beta v8 - LATEST)
16 Gb memory Geil 2133 Mhz
* Disabled SWAP file in Windows.
** Game, DirectX, System and PB updated.
Waiting for a solution EA!
Another person here with a very similiar setup... Except I had this problem in BF3 as well but only after upgrading to Win 8. I'm running Win 8.0, latest AMD drivers, HD 6950 flashed to a 6970, 8 GB of RAM, AMD Phenom II x6.
No issues in the beta but I'm guessing that is because the beta was a single map.
After having the issue and haulting BF3 play, I'm seriously considering buying an Nvidia card tomorrow. My jaw dropped when I bought BF4 today and saw the same issue. The answer to the BF3 problem I had was "Win 8 isn't supported"....
