I recentley upgraded my hd 4350 to a Hd 6850. Playind call of duty black ops on my previous grpahics card i got a steady 17-18 fps. now with my new graphics card one moment i get 50 fps then suddenly it drops to 9 fps this goes on and on. Why do i get a sudden decrease of Fps ? one can never play this game like this..

My specs

Core 2 Duo 2.93 GHZ
2 gb ddr 2
Xfx hd 6850 black edition
cooler master 500w extreme power plus

You are also only running at 1280 x 1024...

My best guess is also a memory bottleneck, that is why it runs great for a few seconds until the mem allocation fills up, then drops massively while it clears the cache, works until it is full, and rinse and repeat. :(

the 6850 is a heavy hitting card, but you need the processor and ram to be able to keep up with it.

yeah but you dont know what else is hogging his mem......his process tree could be a mile long for all we know.......

its a cheap upgrade.....but start with the free one and re install your drivers (after uninstalling of corse)

and then toss in another dimmstick
