My latest display driver doesn't support WDDM 1.0, and I need it to be at least version 1.1.
I've been attempting to get the Windows Phone 7 SDK working on my HP Pavillion dv9000, but the phone emulator requires 1.1 or higher. My drivers are as up-to-date as they can get. I even tried a modded driver found here, but no go.
Then, while evaluating Windows 8 Developer Preview on a different partition I noticed that dxdiag.exe showed it was using WDDM 1.2. I tried installing Windows Phone 7 SDK on Windows 8, but I get an "Internal Error" popup and "Connection failed because of invalid command-line arguments" in the error window in Visual Studio. I'm guessing because Windows Phone 7 SDK isn't supported on Windows 8 yet.
So my question is this: Can I get Windows 7 to use the display driver Windows 8 is using to get WDDM 1.2 on Windows 7 and how would I go about doing it?
