Guild Wars 2

I just started playing guild wars 2 recently and randomly my character and the environment started tearing and strips of colours started coming out of my character and the environment. When i exited the game to desktop, there were white dots/pixels everywhere on my desktop and whenever i started the game, the strips of colours coming out of my character and the environment were still there. I uninstalled then re-installed my graphic card and that seemed to fix the problem. This problem happens randomly while i’m playing the game, sometimes an hour in, sometimes 5 hours in. Every time this problem happens, i always have to re-install my graphics card. My drivers are also up to date. Here are my specs:
Graphics card: ATI HD Radeon 6870 with 1GB of memory
Processor: AMD Phenom II X4 955
Motherboard: MSI 870-G45
4GB of DDR3 RAM

I’m not sure why it happens but i know for certain it has to do with my graphics card because when i disable it when this problem is occurring, the white dots/pixels disappear from my desktop, of course i cannot play the game while my graphics card is disabled. I play the game on the auto-detect settings. Any suggestions of fixes? or this this a game bug? Thanks.

The white dots/artifacts might be due to overheating you can monitor your graphic card temps. Also try to limit your ingame FPS to 60 or 30 see if it helps.

Okay, i will limit my ingame FPS to 60 or 30 and monitor my GPU temp and see if that helps, thanks.

How do i know how low i should keep the temperature or when it will over heat?

Stay below 90C. Try also setting up the fan to 60-70%. If there’s also dust building up inside your case and gpu try cleaning it as well either dusting if off or by compressed air canister.

Okay, Thanks for the support.

From another game I recently played it was suggested that tearing could be caused by having Vertical Sync enabled, IIRC.

I have the same exact video card you do and I don’t experience this issue. I do not overlock my cpu nor use crossfire, if that matters.
