Well, if you have a laptop, or vista, it should be slow cause they take up lots of graphics without the game running, and they aren't really meant to be used for playing these types of games in general. Just kill some processes that aren't important, close some windows (including this one) and run Combat Arms directly. If that doesn't help a lot (which it shouldn't) then look for some help threads. I think there was one that helps you improve your Combat Arms speed by a lot.
