According to the guide at the top of the forum: "As it stands right now Nov07, Windows XP is the better choice for running Windows games under Boot Camp. Vista has higher overhead and the Windows community is still trying to get the driver issue corrected. In other words, Vista drivers tend to be slower. The primary appeal of Vista is Direct X 10 which has a higher graphics quality than DX9. However it could be argued that if you have to run your game on low settings what's the point?" Has this opinion changed in the last 1.5 years?
