I rolled back to the 327.23 drivers and this issue, as well as some other ones I was having with the 331.58 and 331.65 drivers in other programs appear to have completely vanished.
I'm running SLI EVGA 650 Ti Boost SC 2gb, in Win 8.1 x64, and after testing it, I've regained my ability to limit my FPS to 60 (I get nasty screen tearing with my monitor) in Precision X without still having screen tearing issues with the newer drivers, my FPS doesn't budge off of 60 at all in any situation on Ultra with MLAA 2x, the occasional "Driver has stopped responding and recovered" issue has gone away, and benchmarking scores have gone up a decent amount. Even the rarely occuring Firefox hiccup has disappeared with Hardware Acceleration on.
And, most importantly, after hours of goofing off in Test Range and SP, I haven't gotten the DXGI_Error_Device_Hung problem at all. I can't speak for ATI cards, but it appears that a good bit of this was on the driver end for Nvidia. Don't trust the new drivers, unless you're actually going okay.
But just to test, after getting a driver crash in a few games on Steam, I decided to stress test my cards to make sure it wasn't any hardware faults, and after running Valley and Heaven benches for about an hour each, both ran with pretty much expected performance.
So, I booted into safemode, did a clean wipe of the 331.65 drivers, restarted back into safe mode and installed the 327.23 driver. I also left out the stupid Nvidia Experience thing because it's annoying and doesn't really serve any use other than harassing me the occasional pop-up.
Someone else should give rolling back to older drivers a go and see how it works out. Correlate things! For Science!
I'm equally frustrated with QA on this game. Shocking that they can release BETA code to the open public for forty five quid. Disgusting!
I run on:
Mac Pro Bootcamp'd
6 gigs DDR2 800
6870 1GB GDDR5
Windows 7 Ultimate
ATI BF 4 BETA drivers
This runs for no more than 30 min on High detail settings. I gain 15 min if I switch to Medium detail settings. I decided this was an excuse to get a 3D card with more memory as I heard the game is very memory intensive.
MSI Nvidia 760 2GB Frozr
Nvidia 331.65 'BF 4' driver
Now run on Ultra settings again last 30 min before a hard lock or Direct X error and the game hangs. Based on previous results I'd estimate on High settings I'd get an hour of play on this new card.
Smells to me like memory leaking. Be interesting to monitor the 3D card memory usage over that 30-1 hour duration to see when it peaks. Check the bottom of this page for estimated memory usage. Shows something is afoot if through my research so far it just bombs out quite religiously based on detail setting and 3D card memory size:

P.S. can people elaborate on what they are changing with respective overclocking software? Or is it just installing of it that changes BF 4 behaviour??
For me I think noticed it popping up when turning on vram intensive settings. Some things like detail level have no no real effect, but texture filtering and even full screen were setting it off. (On Ultra.)
