well, that's also you're problem, there aren't drivers for linux for vmwares, "technically". since it's virtual machine, the HAL supporting it is also virtual, so you'll never get any performance out of it for any games.
if you had a dedicated linux box, then yes, under WINE it would run fine.
There might be a misunderstanding... I ment that I was going to see if my graphical drivers are supported for linux, then I might install linux as my "main" os, so i get rid of vista
