What’s the difference between playing World of Warcraft under Vista versus Linux Fedora 10? About 40 FPS.

Vista plays the game between 10 to 20FPS.
Linux Fedora 10, with Wine windows emulator (!) plays it betwen 40 and 150FPS, depending on the scene complexity.

So, although linux is emulating windows, it still does a better job than the “native” windows which is buggy and slow (which we already knew).
