根據下面這篇 http://reviews.cnet.com/4531-10921_7-6546370.html 有提到 Parallels doesn't officially support DirectX yet, but that didn't stop us from trying to run Quake 4 on it anyway. Alas, it was an exercise in futility--it did not work--and in fact, at one point, even forced a spontaneous system reboot! Surprisingly, with the game resolution set to 1,024x768, Quake 4 actually produced noticeably faster frame rates on our test than with Boot Camp. Perhaps the Mac has a future as a gaming platform after all?
