Does this happen when you play a video on youtube? Did this issue start ever since you got the card? Also, is there anything else running in the background such as anti-virus or real-time monitoring programs.
sounds like a bad card to me .. if you have been playing bf3 lately there servers are messed up so its not just amd cards its also invidia .. lag stuttering what ever you wanna call it .. only thing that helps is to do a repair install on your game through origin..
Ah true. You mentioned you have BF3 right? Check and make sure origin is not running at all. if it is shut it down and try playing a game, see if it helps. Origin was pulling some funny business with me and even with BF3 on low I would get >20fps (I have a 6870 + athlon 2 x3)
check the temps on your CPU and GPU. i noticed lags on my GPU when it hits high temps also. maybe the GPU fan collected dust after awhile and needs to be clean? do you have good ventilation in your case?
I had various stuttering issues with windows 8 RTM, that all of them was solved by simply enabling hyper-v on windows "programs and features" > "Turn Windows Features ON or OFF" (under control pannel, programs).
It was unacceptable that windows 8 (which is suposed to be faster than windows 7) could not do some simple tasks, like playing a song or browsing the web, without stuttering alot, so I googled and found the answer.
I found the answer on a blog, I don't have the address, sorry, but it helped alot, expecially with firefox.
Anyone who got any stutter under windows 8 should give it a try, although I don't know if this hyper-v feature does anything at all, but it solved my problem.
