lol. Mobile computers aren't meant to play Combat Arms unless you're running a 48xx+, or a 9800M +. It uses shared memory, so you basically have like... 64MB dedicated, if that. And your frames will do that shitty drop because of overheating. My guess is your computer is running at like 70-90C when playing CA. I have a ventilation system for my laptop, and it maxes out at 60C which is pretty decent.
