how to detect WDDM vs. XPDM

Martin

Hello,

How can I programmatically determine whether Windows Vista is using a WDDM
driver or an XPDM driver?

I can enumerate the drivers and obtain a name such as:
RADEON XPRESS 200M Series (Microsoft Corporation - WDDM)

but there's no guarantee that all WDDM drivers have the string "WDDM" in the
name.

Is there a preferable method?

In user-mode:
Check if the Direct3D device has the D3DCAPS2_CANSHARERESOURCE capability.

ya i am also having the same problem are there any API's available through which we can check weather a Vista is having a XPDM driver or WDDM driver ..but not by enumerating drivers!
