Windows Vista already comes with both DirectX 10 and a special version of DirectX 9 called 9Ex, which is basically the same as the regular one except it supports some new features of Vista. Vista SP1 includes DX 10.1 as well.

I see, thanks for info. Is it automatically activated or does it require a manual switch-on? Just curious because i did a test with a 3d tool and it said i need to activate direct-x 9 or 10.
As myiope implied, it depends on the application. Dx10 is a new technology so not many applications make use of it. Dx10 is usually not the default render engine and isn't even an option without the capable graphics solution.
