Gameplay speed

[Trebax]

I've got a gameplay question:

when you guys are walking around the world or in a base, does the game seem slow at times? Almost like the game is too much for the video card or processor?

I am having trouble with this, especially when i am in action. The game gets really slow and i can not react. I am running a 1.5ghz with 256ddr ram, a geforce2 ultra 64mb and i have a 13gig hard drive which is almost full. Any suggestions on how i can get faster gameplay? I guess its time for me to get a new video card again anyways.

Thanks
