ATI 7850 Saphire OC - Artifacts/Texture issue only in Guild Wars 2


I have been the happy owner of a HD 7850 Saphire Factory OC (I have not OC'ed this any further myself) for about 3 months now, and it has ran flawlessly for that time.

I do not play many games and I started using CCC 12.4 and everything was fine while playing Starcraft II, Guild Wars 1 and Diablo 3, then I upgraded to CCC 12.6 no issues, and 5 days ago just before Guild Wars 25 August Head Start I upgraded to CCC 12.8 again no issues in Starcraft II, Guild Wars 1 and Diablo 3, no issues in 3D Mark 11 and getting the expected score for my system P5897.

Complete build:

HD 7850 Saphire OC (Default OC) currently running 12.8 WHQL drivers, CCC has everything at default.
i5 2500 K (Not OC, just turbo enabled to 3.7Ghz)
16 GB Ram Corsair at 1333 Mhz (Did not want to activate XPS because really what's the point in faster ram?, I think it is already very fast at 1333)
7200 RPM Hard Drive 6GB/s
ASUS Maximus iV Gene-z/Gen 3 motherboard
Windows 7 Professinal 64 Bit

I have not played Guild Wars with any other drivers than 12.8, so today I will try to rollback to 12.4 and see if that fixes anything. But here is what is happening:

Capturing this picture using screenshot was impossible, the flashing light blueish artifacts are extremely fast, in fact I played for 5 hours straight on release date, and only at times did I feel like I saw something wrong in the screen, but though it was me blinking or something...

The second day while in Divinity's reach I saw some obvious ones just standing still, but they also happen if I am moving. They last maybe 1/10 of a second if even. So what I did is take a video and then got the frame where it happens.

On the picture you can see a really big artifact on the top right corner, and several small ones on the left side. I am running absolutely everything on Maxed and GPU-Z gives me a steady temp of 58-60 C, with a load between 60-95%, and the core clock and memory clock running at maximum frequencies pretty much at all times. which is 1250/920 for this card at the default Saphire factory OC

Besides the artifacting i also found texture flickering like in this picture, this one happens a lot more often and random rectangle textures get illuminated:

In the screenshot the top row the item on the right is illuminated for no reason, same with the last row middle item.

I am not sure what is going on, since this artifacting/texture only happens in Guild Wars 2. What could the problem be?, anyone else experiencing this issues in Guild Wars 2?, I have seen some artifacting/texture videos in Guild Wars 2 but those are a LOT worst than mine. The artifacting happens rarely and is very very fast.

I tried lowering the graphics setting for Guild Wars 2 but still seeing the same issues.

Any suggestion, ways to identify the problem are more than welcome.

Thank you,

  1. Just saw some small 1cm white squares flash extremely fast on Diablo 3 auction house menu, never seen this before... So I definitelly think it might be a deiver issue now, didnt have this problems before 12.8 whql... Will rollback now.

    I saw a thread in guru 3d about 12.8 whql some people have the same artifacting while others seem to be fine... I think the artifacting is just too subtle/fast to notice at first, in fact I played for several hours Diablo 3 in 12.8 and I just noticed it yesterday...

    Bottom line I think 12.8 is defective.
