    Default Screen Artifacts with Radeon GPU

    I'm stuck running with low-quality graphics rendering since anything higher produces flashing screen artifacts or strange ground effects. I have a pair of Radeon HD 5570 GPUs in a Crossfire set-up with a Phenom II x6 2.80GHZ CPU and 8GB of RAM, and have had no trouble with other graphics-intensive games. I've tried every suggested fix I could find here, including RadeonPro and FurMark stress testing (plateaus at 50C with no visible artifacts), but have had no luck. I suppose I could keep running with the generic WoW-era graphics at 50+ FPS but I was really hoping for better. Does anyone have another idea short of just dumping or upgrading the Radeon GPUs?

    i was gunna say.. why crossfire those cards? x.x so much headache. i found hd 5770 crossfire wasnt enough for me before my recent upgrade.. and that was if i could get crossfire working... lol. But what drivers are you running?

    Thanks for the reminder, I had downloaded the 11.4 preview driver and the cap1 profiles but forgot to install them. Running on medium graphics now with default settings and getting 50-60 fps, so far so good although GPU load seems very high. Now if I could just stop the repeated game crashes that started this morning as soon as I arrived at Sanctum . . .

    Not sure if its an option for you to test, but you could remove one of the cards and least that way you'll know that it is a crossfire driver issue.

    Thanks! Been playing now for 4-5 hours on medium graphics setting with 50-60 fps and no bugged graphics at all so I think its all set (at least until the next patch!!!). Installing the latest Radeon preview driver along with the latest profiles looks like it was the right combination.
