DX11.1 on Windows 7

With today's announcement of DX11.1 support on Windows 7 (http://blogs.msdn.com/b/chuckw/archive/2012/11/14/directx-11-1-and-windows-7.aspx) what do I need to do for D3D_FEATURE_LEVEL_11_1 to be enabled.

 

I have installed the IE10/DX11.1 patch and the Windows 8 SDK, and the latest Windows 7/8 driver (Catalyst 12.11 Beta 7).

 

My program is able to successfully QueryInterface a ID3DDevice1 and ID3DDeviceContext1 interface so I can access the new DX11.1 functions.

 

However I only seem to get D3D_FEATURE_LEVEL_11_1 on my Radeon HD 6600M series GPU, which I understand to be based on the Evergreen architecture.

 

Does my GPU support D3D_FEATURE_LEVEL_11_1 (on Win 7 or 8)? I don't have Windows 8 to be able to verify this.

 

If it does not support full D3D_FEATURE_LEVEL_11_1  feature set does it implement some parts like logic ops (from OpenGL 1.x) which are already exposed via OpenGL 4.2/4.3?

 

And what about some of the optimisations that have been added to various buffers and views that are exposed via DX11.1?
