Windows 7 marks a dramatic improvement in the way the Windows operating system takes advantage of the GPU, using it for both graphics and computing through the GPU-accelerated Microsoft DirectCompute API. This enables not only more visual and interactive experiences but also the speed and responsiveness that customers want. We have worked closely with Microsoft on Windows 7 for several years now and we are confident that our mutual customers will be very pleased with the results.

We consider DirectCompute a tremendous opportunity to broaden the reach of GPU Computing. We believe DirectCompute will take GPU computing from a niche to the mainstream by making this technology available to the millions of users of the Windows 7 operating system.

NVIDIA is also very excited about DirectX 11. It will be the API of choice for some of the top gaming titles starting in 2010. NVIDIA’s recently announced DirectX 11 Fermi architecture will be well aligned with these new gaming titles. But, Power Gaming with Windows 7 extends beyond new visual effects. Today’s gamers demand more interactive experiences and the technologies that make up Power Gaming are set to deliver a new level of immersion that will transform the gaming industry for years to come, such as NVIDIA 3D Vision, NVIDIA PhysX, and NVIDIA SLI.

So it looks like Nvidia will be supporting DirectX 11 and all the what it will and won't support guesswork can cease. If the email I got 10/21/09 is accurate, and it's directly from Nvidia, then the New 3xx cards will support DirectX 11.
