hey i have the halo 1 demo for pc and i use it to play online and when ever i join a game, it starts to get sooo slow and if i run upto a car, then it pauses for a second and i end up not even close to the car. And in the middle of gameplay, a little icon would pop up at the bottom of the screen and when ever that is there it makes the game freeze. whats going on here? we just recently format our computer so everything is fast on it. so then whats the problem?
