I have been getting some artifacts in Guild Wars 2 using 12.8 WHQL drivers, so I went back to 12.4 WHQL but had the same problems.
I also noticed once some really small white squares in Diablo 3 auction house, but this only happened once.
So I ran 3d MARK 11 without any issues, and then tried Unigine Heaven, I saw white artifacting like this flash extremely fast, and saw a total of 4 in 30 minutes. I was glued to the screen trying to find artifacts for those 30 minutes...
See hazy "cloud" envolving city and part of the bridge.
And in Guild Wars 2:
(See light blue flashing in top right corner and left side)
(See squares illuminated for absolutely on reason at all), this is the ONLY artifacting/flicker I can reliable reproduce, all other flickers are completely random.
And in Diablo 3:
(See small white squares on second from the bottom line)
I have never ever experienced any issues with the card in the desktop, and have only seen it in Diablo 3 once in about 200 hours of play...
The temperature is always max 60 C checked with GPU-Z.
I am just not sure if the problem is with the card or not... I want to RMA it, but I just want to make sure the card is defective first, or if perhaps this errors are normal with Unigine Heaven and Guild Wars 2.
I guess what I am asking is if occasional artifacts are possible in perfectly working hardware for Unigine, and if it is possible that Guild Wars 2 is just such a new game that it has graphical glitches.
Notes: Games or computer has never ever crashed.
The only artifacting/texture flickering I can reproduce easily is the second Guild Wars 2 screenshot, where the icons get illuminated for no reason at all. All the others are completely random and may happen anywhere.
