NVIDIA Presents Support for Windows 7 DirectX Compute
In an internal presentation perhaps to its primary clients, NVIDIA presented support for Windows 7 DirectX Compute. For a welcome change, the slides show no signs of NVIDIA's own CUDA technology, and in turn promise huge performance gains when a Windows 7 machine is aided with an NVIDIA graphics processor. The gains NVIDIA predicts range anywhere between 2 times to 20 times over plain CPU-driven processing, focusing on media-related applications such as Cyberlink PowerDirector, MotionDSP vReveal, and of course Badaboom.
DirectX Compute API will be natively built into Windows 7. It supports both existing DirectX 10 compliant GPUs, and future DirectX 11 ones. Along with pledging full support for it, NVIDIA also explains how the GPU becomes an increasingly important component of the PC, being "central to the Windows 7 experience". As a bonus tidbit, it adds that on Windows 7 the SLI multi-GPU technology works 10% faster than on Windows XP.

Cuda is better for Geforces... but not supported by others.
OpenCL and DX11 Rulz ^^
CUDA -> Proprietary to Nvidia, but multiplatform
DirectX Compute -> Runs on more than Nvidia hardware, but Windows only
OpenCL -> Runs on hardware from all major players, and platform independent.
btw are there at least some OpenCL apps out there that are good and as fast as CUDA equivalents?
openCL doesnt do anything for me yet, so it doesnt count either.
CUDA/Stream are destined to be short-lived technologies because they are proprietary.
I doubt OpenCL will gain much traction either because it was made by Apple and Apple puts everything on an extremely short leash (ultimately choking it to death).
An expanded version of OpenGL is more likely to succeed but it will be some time before that happens.

cs 4.1 -> dx10.1 gpu
cs 5.0 -> dx11 gpu

"better than XP" , should compare it with vista i think , vista dx10 better thanx xp dx9 , they most compare DX11 with DX10
why?, vista drivers are made to run in user level not in the horrible kernel level as in XP
That's so called , erm , nvidias hyping.
I think intel intends to update havok to work via GPGPU/compute shaders, and then let anyone in on that (cough, mostly ATI since they've been working on it for a while)
hopefully, game devs will use that instead of physx - works on more cards that way.
... but I'm sure there's some nvidia contract that will prevent that.
its not a problem for us, but it is a problem for Nvidia
