Last night I updated my drivers and when i started to play ArmA2 today the trees and foliage had white pixels on them in mid range. If I moved closer or farther they would disappear and even when I got out of a vehicle at times they'd be gone. This did not occur before I had updated the drivers however it did occur on another computer I had earlier attempted installing it on to test its performance between the two. Performance of the game now seems significantly worse after I updated the driver as well, I now get rather bad fps even in the middle of a field for no apparent reason at times whereas earlier it did not. Actually come to think of it I also get better fps where it was terrible too, for example walking into a tree earlier had shot my fps down but now it's been fine and terrible which is rather odd. I've messed around with the settings in a load of different combination's and nothing fixes this.
Spec's on the computer I currently play it on:
9800M GS
4GB Ram
2.3GHZ Dual Core

Ok so.. when I mentioned changing settings around I meant on the other computer which I didn't clarify, I did it again and the white pixels are gone, and it runs better even, I went from all high settings to turning anti aliasing to low and everything else to very high and it runs fine.
Other computer I had tried it on:
8800GT
3GB Ram
2.4GHZ Quad Core
