Hi!

Is the new G92-94 core DirectX 10.1, WDDM 2.1 support? I think when more GPGPU programs come or you play in a window with sweet WPF apps running, or a media player using PureVideo and a WPF app it would be smoother operation?

No. It's a DX10 card. It does not have DX10.1 support. As for everything else, I have no clue.

Uhhh... :eek2: no G92-94 core is DX10 and WDDM 2.0, for DX10.1 and WDDM 2.1 you need a new card (Ati HD3000 series are DX10.1 compatible and WDDM 2.1)

Direct3D 10.1

Direct3D 10.1 was announced by Microsoft shortly after the release of Direct3D 10. It will be a minor update to the Direct3D 10 interface, adding features that had to be left out of the initial specification. Direct3D 10.1 sets a few more image quality standards for graphics vendors, and gives developers more control over image quality.[15] Its feature will be supported exclusively by new hardware.

The Direct3D 10.1 API will be included with Windows Vista SP1, which will be available mid-March. The specification was finalized with the release of November 2007 DirectX SDK. [1] Direct3D 10.1 will be backwards compatible with Direct3D 10.0 hardware, but the new features will not be available until 10.1 compliant hardware is released. The only available Direct3D 10.1 hardware as of November 2007 is the Radeon HD 3000 series from ATI and the upcoming Chrome 430 GPU from S3 Graphics. NVIDIA will not be releasing any hardware to support Direct3D 10.1, the first GeForce 9 cards to be released will use GPUs from GeForce 8 series cards which support up to Direct3D 10.0. NVIDIA plans to go straight to Direct3D 11; but the first GPU specific to GeForce 9 series, is scheduled to be released before Direct3D 11.[16]

Direct3D 10.1 features bigger control over antialiasing (both multisampling AND supersampling with per sample shading and application control over sample position), more flexibilities to some of the existing features (cubemap arrays, independent blending modes). Direct3D 10.1 hardware must support the following features:

* Mandatory 32-bit floating point filtering
* Mandatory 4x anti-aliasing
* Shader model 4.1

In Vista all the things that are in your desktop are showed via DirectX runtime (D3D9ex), that means all is Direct3D accelerated with proper Vid Card (DX9/10 and 256Mgs more or less) you have a 3D accelerated Desktop.

The new driver style is necessary because, although Vista uses something very close to Direct3D 9 for its display, it's not quite identical. The new version is "Direct3D 9Ex." As the name suggests, it's very close to Direct3D 9, but it's been extended. D3D9Ex simplifies some aspects of D3D9—for example, some features that are optional in D3D9 are mandatory in D3D9Ex—and makes some changes to better facilitate the use of D3D by multiple applications concurrently. Just as with people using under-powered video cards, people using XPDM video drivers will have to forego the DWM and all the effects that Vista will offer.

heres a better one, also explaining why OpenGL really loves Vista

No, Vista still is old GDI+, the OS just draws to 3d textures on the 3d card instead of a frambuffer . Look how old programs with windows in their window have tearing. WPF applications however, and probably Windows 7, is fully vector based and floating around in hardware accellerated heaven (http://www.youtube.com/watch?v=1YwCev1p1U4) on our 3d cards. :)

... for example, some features that are optional in D3D9 are mandatory in D3D9Ex—and makes some changes to better facilitate the use of D3D by multiple applications concurrently.
A bit bloated this quote but what is important is he say D3D9Ex and vistas driver model moves Direct3D to a client-server type driver, just like OpenGL has been all this time.

Ah good wddm 2.0. Few article writers mention this, maybe its not as importnat as I think? But if entire OS and programs and games are to be in 3D.. still not sure. Buy a geforce 9 now, or wait?

Wait 9 series are a joke unless you have a 7 series card, if you have an 8 Series card (8800GTX or GTS 512Mgs) is a waste of money, wait for next gen on August

Vista GUI Stuff for developers, good watch:
