Not sure if it's my video card or what, but whenever I enter a Natural Selection server, I skip about 10 frames every other second at a time, and after about 20 seconds, my game freezes and nearly crashes my computer. I've tried HL, and it works fine; no problem there. I haven't downloaded anything new lately, or added any software or whatnot; I just haven't played in a while. I updated Steam..
Any other questions that need answering before somebody might find a solution?
