Bad Company boosting performance

[Peter450]

This game generally runs quite nicely, but when there's lots of action in front of you, on some folliage dense maps it can drop below 30 FPS which i hate

I have a dual core running at 3.8 and a GTX 280, is the proccesser not being quad core holding it back or will a card overclock/replacement see the biggest gains?

I'm running high settings and want to keep it that way to be honest, on the more sparse maps it's fine all the time, but on the more dense maps when your at certain parts with people running all over it can bog down slightly and i'm keen to get rid of this

On the setting's it's got AA set at 1X, yet in the game there is no way to turn it up or down, i looked in the setting's INI file and could not find an AA setting

HBAO how does that affect the quality if you turn it off?

I've got XP so i think thats DX9 already

Thanks guys, i just downloaded the latest Nvidia Drivers (had 194 before i think) and it's made a noticable differance, so might not have to turn anything off after all
