usually the performance is too poor or unreliable except in the case of very old games.
This is far from universally true - in my experience it is actually slightly backwards. A few years ago I had to benchmark a Windows program against a Linux one I had written, and the Windows program ran slightly faster under WINE than under Windows. (This was mostly computational, without much use of Windows APIs, and no graphics in the timed sections.)
