Ok so I have Windows XP Home installed with bootcamp and I am trying to play Splinter Cell: Chaos Theory and it lags horribly in multiplayer. The single player graphics and framerates are superb but when I try to do anything in the multiplayer menu or game it lags BAD. I have tried the boot camp drivers and I have tried modified drivers from laptopvideo2go.com and I get the same result. If anyone has any suggestion please help! Thanks... BTW I have the 15" latest generation with the 8600m GT card. I don't know if it is software or a setting conflict. Also, the game patches are up to date.
