Hexo...are any of your cards overclocked?? Even factory overclocked?? I have done some some looking around internet and found that most believe this device hung error comes from instability of the GPU memory when the card is overclocked...and thus to fix it, you need to turn it down to the standard level.
No overclocking, just standard EVGA GTX 660. Underclocking is not an option. The problem is at the programming level, perhaps in the Frostbite engine itself. Fortunately, I save a LOT so the only time the crashes were a major headache were some very lengthy cutscenes that had to be repeated a few times and skipped through to make it to the other side. Game only crashed once or twice outside of cutscenes and that's in a 160+ hour game.
