I really dont remember well but this problem started 1-2 months ago after i formatted pc or buyed new system.I was using same card MSI HD6970. So i buyed another msı hd6970 for crossfire but i still got texture flickering problem while looking far distances. It only happens when i look far away in wow and bf3. Especially its more noticable when i use sniper scope in bf3 like in this video..
Err? 750 W for 2 x HD 6970? Seems a little low, but not sure.
I didn't realise you said they both do it even when tried alone, oops. It may not be an actual problem with your card, but nonetheless it's possible. I've noticed the same thing with my GTX 560 Ti on Blacklight Retribution.
i was using single one with 500 watt before without any problems.Then i buyed 750 watt. It started right after i buyed new system.After i buy the new 6970 i tried it alone without the old one. It does the same thing also. I dont think its possible that both graphic cards have problems.
