I got this game when I ordered my computer about 8 months ago. I popped it in, installed it, started playing it... and the mouse is laggy as all get out. Haven't played it since. The game runs perfect it's just when I move the mouse it moves slow even at max scroll speed. I was just wondering if there is something I'm missing? Like a certain setting on this computer I have to turn on or off, or a certain setting in the game I have to turn on or off. Any help would be appreciated.
Actually the solution is really easy, just turn on the Vertical Sync for the game (the problem is Halo 2 does not have Vertical Sync option).
You can google it and find out how to do it though.
