SAME WITH ME!!!!! i get horrible lag in single player, its not the lagg acually i think its the FPS and i put that on the highest!!!!!!! but still no luck of running smoothly
thats wierd i have a sililar sytem to you, but mine is a amd 64 3000+
with a radeon 9600 pro.
halo runs fine on mine, and yes halo is only one cd.
even in single player is flawless...
did you try reinstalling the game? im sure you did so i dunno....
yes its a legal copy, but usually games like this come with multiple cd's (2 for isntallation and 1 for play), but this one is only one cd so i was just wondering.
