So, I just got my 2GB 6950 today, and I'm having a couple problems with it.
1. Whenever my multisampling up past x4 (In WoW at least,) I start getting this kind of static. This also happened when I turned the AA up in Bad company 2.
2. In WoW I noticed a significant decrease in performance since installing the 6950. I have CCC installed and it seems to be working. My old card was a GTS 250 and I usually got about 60 FPS on average with maximum settings.
With the new card my fps jumps around from 25-70. (Maybe it's just a problem to do with WoW?)
IN BFBC2 however the performance was greatly increased.
Any ideas on why this would be happening? I haven't overclocked anything yet, everything is stock.
It's kind of hard to see in the picture, but along the railings in the top right, it gets really bad when I move around.
I got the 6950 about a week ago and ran into the same problem. Benchmarked against my HD 5830 and the 5830 won by a mile. Even though both cards were ATI/AMD I had to uninstall CCC, use a driver sweeper and then download and install a new copy of CCC with APP. Now it works fine and I am seeing the gains that I expected.
I just bought a HIS Radeon HD 6950 Iceq X Turbo 2Gb and I am having similar problems in a lot of games. I thought it was a faulty card to so I RMA'd it and got a new one, but it still does it. The new card runs 10C lower at idle and under load, but I still have this issue. I am going to try doing the driver sweeper thing like Losolo suggested.
