Well, it's Windows 7 and Windows 2008.

The various VMware graphics drivers all act a bit differently. VMware 
drivers are getting better and in theory it's possible to enable 
"Accelerate 3D Graphics" on several platforms but that leads to crashes 
(the whole guest that is) for one or more of the ddraw tests. So the 
drivers are not there yet I guess.

Doesn't the DXGI_ERROR_NOT_FOUND return value tell us there is no D3D10 
capable adapter (instead of any adapter)?
