Does the newly released Microsoft Vista Beta 1 include the successor of DirectX9c? if so I think I have read somewhere that nvidia 7800 fully support the next version of directX (possibly named something else) So I'm wondering if this is true or not, and if it can be tested in beta 1 of Vista. I'm thinking of buying such a card but dont want to spend all that money if the coming version of directx is unsupported (7800 doesnt take advantage of the new features that is shipping with the new version).
EDIT: Windows Graphics Foundation 2.0 (WGF), also known as Direct3D10
The next version of "D3D/DirectX" will be WGF1.0, THEN they will release WGF2.0 afterwards. The base/minimum of Vista is DX9 feature sets, for all the bells an whistles of the OS you need WGF1.0 support, then WGF2.0 will be the extended version you likely have to add yourself afterwards just like enhanced versions of DX now.
GF7800 may support all of WGF1.0, but we won't know until it's truely finalised and detailed (maybe it falls short of one tiny aspect of the standard [like the GF4ti and DX8.1 or Parhelia and DX9]), but it defiitely will not support all the features of WGF2.0, and neither does the R500, and supposedly neither will the R520 or 580. WGF2.0 is far beyond even just adding unified shaders.
