7850 poor performance in BF3?

[Silverforce11]

If u have periodic slow downs that isn't consistent = most likely you have a nasty virus or heaps of them.

Hmm, I do not think that explains why my gtx280 plays the game plays fine?

I have carefully gone through looking for applications running in the background / monitoring system resources, as well as ensuring old drivers have correctly uninstalled.

Thanks for the suggestions tho, keep them comming. =]

I am afraid the same old problem has reared its ugly head. Not sure why it played nicely for the one day only to relapse into its old habits.

(my old 280 is playing bf3 with more fluidity than the 7850).

Power tune maybe throlling your 7850. Test with power tune +20 or stock clocks to see if it still lags.
