I posted most of this as a reply in another thread, but since I heard from a few people who had the same issue/fix or were helped by this info, I figured I'd make it a topic.

PREFACE:  Most video cards sold today are "factory overclocked".  The manufacturers of the cards DO NOT test this thoroughly on each card, it would take too long.  The solution mentioned below will possibly work for you EVEN IF you have left your card at the "stock" clock settings (which are really stock-overclocked settings).  I have had this issue with two different brand-new GTX 570's which function normally (and overclock pretty well) in every other game or benchmark I've tried. 

Do you happen to see a little repeating pattern of green artifacts over every section of the screen, briefly, before the DA2 app shuts down or the PC reboots?  I do, but it doesn't happen every time so don't stop reading yet if you haven't noticed that.

I've had two GTX 570's now, and it's definitely a graphics memory issue that I have - but replacing the GTX 570 hasn't helped! (although it did make it happen much less often).  I find that if I turn the memory clock on the card lower than the stock setting, it seems to fix or drastically reduce the frequency of the crash/BSOD issue.  (On my MSI GTX 570 OC, I eventually went from 2100 memory clock to 2025).

I think a lot of these newer video cards, especially the 500 series by NVidia, are being "factory overclocked" too highly by the various manufacturers because they're not testing the overclocks well enough.  DA2 is the only application that is video-memory-intensive enough to cause this crash for me (that I can find).  I know heat and power are not the issue for me because I am running a Mac Pro, and if there's one thing they do well it's passively cool the case and provide plenty of power for HDs and video cards (1 kilowatt power supply in my case).  I also test the wattage and the case temperature regularly (along iwth the card's temp too).  BTW I am running windows 7 on my Mac Pro, natively, using boot camp.  I don't even have OSX installed!  So DA2 is the windows version, along with everything else software-wise.

Anyone else noticing DA2 is much more sensitive to overclocks than other current games?  Or is there maybe some chance that a DA2 bug is actually emulating a hardware issue (BSOD and memory arifacts on the screen briefly)?

Please post a reply and let me know if this issue/fix applies to you as well!
