If you get crappy framerate in X-Moto, it's probably because you don't have hardware-accelerated OpenGL. You can run the game with a lower resolution like this: xmoto -win -res 640x480 -ugly This is probably a thing about X-Moto which is both good and bad. Good thing is that it will be nicer and fas...

I'm sorry I'm four years late, but a clone (open source) now exists: http://xmoto.sourceforge.net/

Also, I think vanilla WINE can run Elma now. Vanilla WINE is free, WineX/Cedega costs money.
