wddm 1.1 comes on Windows 7 by default. Not sure but I guess Windows 7 Starter won’t have it.

Hi,
I am trying to install WDM 1.1 on Windows 7. But I could not get any installer which will install it.
Please give me some link which has downloadable WDDM 1.1.

WDDM 1.1 drivers address an AERO related issue:

When using the AERO interface in Vista, old applications using the GDI APIs (instead of eg. WPF) had to render window contents using the CPU. In order for this to work a COPY of the window contents needs to exist in normal RAM (rather than the VIDEO RAM of the GPU).

In WDDM 1.1 the GDI windows are rendered directly in the Video RAM using the GPU.

Using WDDM 1.0 drivers in 7 you miss the opportunity to render GDI windows with the GPU, thus losing memory (and a tiny amound of CPU cycles).
