I have the following:
195.xx Beta Driver
August 2009 D3D SDK
Vista with october “platform update” and all service packs.
I can run DX11 examples, as long as they have downlevel 10 code in HW acceleration mode, however, the “CS” samples that use CS4.0 always fall back to Refrast.
Digging a bit further: The DX Caps viewer reports “Compute - Optional (no)”
The 195 driver release notes explicitly state that the 8800 would have Compute shader support. I also had 185, which also supposedly had this.
On another machine with a 260GTX, Windows 7 RC1, and the SDK, it reports “Compute - Optional (yes)”, and samples like NbodyCS run flawlessly in hardware. It reports CS4.0 capability.
So is there a specific check for vista/W7 that might still exist in the driver? I’ll be getting windows 7 soon, but I was hoping to get this working now on my vista machine (since the rest of dx11 seems to work). It would also be handy for Nvidia to create a chart of what card has what caps on for each OS, if it’s the case there are differences, for dx11.
