im having a problem with my game, now when ive upgraded to windows 7 ultimate 64 bit. whenever i play the game, as soon as i press button on the keyboard, there is a second-2second delay when the screen freezes before the action is preformed. e.g. during driving, when i press the accelerate key, the screen freezes for a few seconds then continues, this repeats with every key i press. Ive tried setting the compatibility to vista, XP (all versions), win 98 and win 95 with no luck.
