Let me start off by saying that I play on a crap computer. I tried so many different things to reduce lag, but none of them really let me run steady at 20 or even 15 fps for an extended period of time. Today, I started playing with around 30 fps and after 15 minutes I was playing at 5 fps! And now, when I try to launch L4D2, it just freezes during the loading screen! I'm starting to get REALLY mad about this. Can anyone tell me anything at all that will help me!?
