get a xbox.
xbox and ps3 are MADE for games, so they play games better than a pc (made for LOTS of other things)
i have a pc (duh, i am on the internet right now.) but i play my games on my xbox 360, because its just better at playing games.
TFU is a great game, the second one is even better, the game works fine, your problems are with the machine playing it. go get a games console and quit whining
