Ive noticed that there is a major difference in performance when 32 bit color is used compared to 16 bit. The game stutters horribly in 32bit and i cannot have most of the graphics turned up. However I have since figured out that when I set the game to run in 16bit color I can crank up the detail without anymore stuttering. The game still looks great and is more playable in the process. I suggest that others try this to see if it will help their game.
