Chuggy FPS on 3870x2 . Driver issue?

[msaunders]

Hi

Wondering is anyone else having the same issues as me .

Asus 3870x2 with Cat 8.3
Vista 64 SP1
4GB DDR2
Q6600 @ 3.2GHZ
Samsung 245B Monitor

Not a bad spec right ? So , why am I getting really chuggy performance in some parts of COD4 , where its reporting FPS of over 100 but yet when I strafe for example, parts of the map chug and skip frames as if its running at 20FPS.

For example COD4 , Act 3, "No Fighting In The War Room" ,after you come out of the Vents walk into the area where there is water coming down from cieling and 2 dead bodies against the shower wall. Now , face them and strafe left and right . On my system it is really chuggy and looks like its skipping frames .. Walk out of there and into another room and everything appears fine again .

Is that the 3870x2 or is it my monitor (refresh rate) causing this ? It seems to do it in a few games from time to time and I am beggining to think its a flaw with the 3870x2 or Cat's

I have tried different detail levels and it still does it . AA and Antiostropic filtering are both disabled.

Anyone else seeing that ?
tks
Martin

use driversweeper and try cat 8.4

Isn't there some beef with COD4 and water and the X2 (but not the regular 3870)?
Check out the bit down the bottom of the page - I've seen it mentioned elsewhere as well...

The 3870x2 is not too great on vista, the 8.4's sorted a lot of issues however I'd probably just wait for 8.5 now, can't be too far off
