We are very excited here at NVIDIA today, because the fact that Windows 7 has hit the RTM milestone means we are on the doorstep of the launch of the first Windows operating system to treat the graphics processing unit (GPU) as a real peer to the CPU.
The model for The Windows 7 PC is to use a CPU and GPU together in a heterogeneous computing platform. Previously, GPUs were almost exclusively limited to rendering and accelerating graphics and video. With the introduction of Windows 7, the GPU and CPU will exist in a co-processing environment where each can handle the computing task they are best suited for. The CPU is exceptionally good at performing sequential calculations, I/O, and program flow, whereas the GPU is perfectly suited for performing massive parallel calculations. With the introduction of DirectX Compute in Windows 7, Microsoft is really opening up the immense parallel computing horsepower of the GPU natively right in the operating system.
So what does this mean to you and why should you be excited about Windows 7?
It means that soon you will be able to purchase a Windows 7 PC or upgrade your existing Windows Vista or Windows XP PC to Windows 7, we recommend adding an NVIDIA GPU if you don’t already own one. Applications written to take advantage of Windows 7 DirectX Compute will be able to provide high-quality video playback and high performance transcoding, enabling new media scenarios and extended control over your media library. In this scenario, your PC will be faster and more responsive when you are doing the tasks you want it to do.
As an example of the real world benefits of DX Compute, you will be able to use the massive parallel capabilities of the GPU to significantly reduce the time it takes to manage your media files compared with just using the CPU alone. With new software designed to take advantage of this capability you would be able to copy and transcode (convert a video from one format to another – a very computationally intensive task) a movie to your MTP supported portable media device up to 5 times faster when using the GPU as a co-processor with DX Compute, as compared to only doing the processing on the CPU.
If you enjoy watching movies, you’ll find that Windows 7 introduces a new version of Windows Media Player and Windows Media Center which add in-the-box support for GPU-accelerated high definition playback of any H.264 video content. This will give you the best smooth, stutter-free movie playback with lower CPU utilization, freeing up the CPU to focus on other tasks or to save power.
For the gamers, Windows 7 will provide the best gaming performance of any Windows operating system and will support SLI (multi-GPU gaming), 3D Vision and PhysX on day 1.
Parallel programming is the next big thing for the world of computing – it has started already. DirectX Compute will accelerate this discontinuity by enabling massive parallelism to the masses. What we are talking about is co-processing— essentially using the right tool for the job.
We hope you’ll be there with us on October 22nd to experience the next generation of GPU-powered media and gaming with Windows 7 and we look forward to working with Microsoft to deliver on the highest quality Windows release ever.

@nonamelab: They are definitely going to have DX11 on Windows Vista. It has been confirmed for a long time now, and there is no reason not to.
And just to clear this up (again) Windows Vista works like a dream if you have SP1 or higher and a decent computer (dual core, 2 GB ram minimum).
Part of the reason (to my understanding) on why DX10+ won't be in Windows XP is because of the major shift in driver model and a lot of other things. Going from Windows Vista to Windows 7 there is no such problem, the driver models are very similar (this is why during the Win7 beta you could use Vista drivers if Win7 drivers were not available).
As to the release date, I'm not sure if they are still tweaking it or not, but they definately want to wait until after Win7 is available to the public.
@anonymuos :Maybe because they didn't decided yet if it will be a Windows 7 only feature like DirectX 10 was on Vista.
They will wait to see the sells of Windows 7 and if that is low the DirectX 11 will not be made available on Vista.
They want to erase the Vista shame and they will do anything to accomplish that :)

I Love nvidia
Why is Microsoft delaying DirectX 11 availability on Windows Vista?
