This is the very difference, intel drivers on linux, are sooo sloowwww on 3d games.
It's not only driver problem, because SS3 isn't optimized for Linux. Wargame, in contrary works better under Linux, so I can say: KDE, XFCE and Ubuntu lead to performance wins over Windows. It's as true as moronix title.
