Hi just got around to installing this and its pretty unplayable, the game wouldent run cinimatics or and would maybe gibe me a frame every 10 seconds or do. it slightly improved when i set it to windows 7 compatability but xp service pack 3 did little to help! has anyone else experianced this? if i alt tab the game then open the screen again it works for a few seconds before it slows down again. main menu ingame menu's behave the same.
