Boot Camp reveals that OSX is slower than Windows

Apple, might be finding out that the problem with having a dual boot alongside Windows is that users can compare both operating systems better.
According to Penny Arcade, the introduction of Boot Camp makes it a lot easier to benchmark what the two operating systems can do.
One of its hacks installed Boot Camp onto his MacBook, installed Windows and then World of Warcraft. To test how the two operating systems compared he ran WoW at 1440 x 900 with all the graphic settings on maximum.
It was barely playable of course but he managed to get a frame rate reading of 15 and 20 FPS under Mac OX.
On the same lap top under Windows and the same settings he managed to get between 35 and 40 FPS. This is a pretty big difference.
The reviewer said that he preferred using OS X, but it was a little difficult to justify when a game runs twice as fast under Windows
