5870 - random extreamely low fps for a few seconds in games (driver issue?)

[engstrom0304]

Hi,
I got my 5870 with cat 9.12 beta drivers

Some games randomly for a few seconds go imensly low fps then really quick a few seconds later, making the game run too fast, then returning to normal.

Have you heard of this exact problem??
I have had no other problems. It did it in mw2 but 9.12 seemed to fix it. (could have been chance)
But it now does it in dirt 2. Does this mean that the 9.12 did not fix the problem for mw2? Or could the beta drivers just have helped on cod6?

I want to be sure it is a driver problem before voiding the warranty installng a gpu block.

sounds like it try other drivers... see if it does it

there are not many out. I will try though. I am running Windows 7 (x64)

i installed the 9.11 hotfix on the 9.12betas
no luck! Might try with the 9.11 in a bit

i have exact same issue with my 5870 911 drivers with dirt 2 hotfix installed

does this happen only on dirt 2?? It is quite reassuring to find another with the problem, indicates a driver issue. Appantely, many people get 5870s to work after reinstalling the os and making sure your reinstall isnt the rc windows 7.
Thanks
Tim

and it does a slowdown to extreamely low fps for a few seconds yes?? Just want to be sure it is the same thing. Cod is fine now i put the 9.12 beta on but dirt 2 does it and funnily enough F@Home!
