hd3870 poor performance cod 4 multiplayer

[TheRealDeal]

I have all the settings on low only 4xaa shadows off and still only getting around 30-40fps average with frames dropping down in the high teens. So the gameplay is really choppy. My x1900xtx was able to run the game much smoother at these settings looking at some reviews they get better fps with all the settings on high so not sure what the problem is here. My pc has been reformatted with a fresh windows install, running the drivers that came with the card, updated mobo bios and chipset drivers to the latest version.


PC specs are e6600@stock , 2gig corsair xms 6400c4 , hiper type r 580 , soundblaster xfi fatality , HIS HD3870xt.

Your graphics card came out just a few days ago, i think its the graphics driver that may be slowing things down cause its still early stages and ati haven't fully utilised the power of the 3870 cards.
Just give it time and i'm sure ati will release an updated driver with performance improvements.

I have noticed you are running your cpu at stock? you can squeeze atleast an extra 600mhz from that cpu if you know how to overclock it. If you leave it at stock, then it might bottleneck your graphics card, but if you just want to stay on the safe side then i suggest just leave it as it is.

Yea i usually run it at 3ghz but got a crash from it the other day so backed it off to stock till i can be bothered testing things out.

Did you install the old drivers and install the new ones?
