Let me repeat; games in DX9 mode in Vista run at the same performance level as the same games in XP
Repeating it doesn't make it true. You need to get your head out of Microsoft's ass and look at a wider range of benchmark reviews. For example take a look at the benchmarks posted in the review at
http://www.tweaktown.com/reviews/1293/1/page_1_introduction/index.html The tests in that review were done under both Vista and XP for three of the latest high-end video cards (two Nvidia and one ATI). Even for the applications running under DirectX 9 on Vista like 3DMark06 and HL2 EP2, there was a measureable dropoff under Vista versus XP, e.g. 8767/9655/11385 versus 9049/9944/11806 on 3DMark06 and 128.41/
133.54/195.34 versus 132.27/
151.35/201.66 for HL2 EP2 for the Nvidia 9600GT card.
