direct3d11.1 id3d11device1 can't use 11.1 features (win7)

I have successfully created d3d11.1 device and it's context (ID3D11Device1, ID3D11DeviceContext1)

using the method described in documentation : 

dxhr = D3D11CreateDevice(adapter, D3D_DRIVER_TYPE_UNKNOWN, NULL, dev_flags,
    NULL, 0, D3D11_SDK_VERSION, &dev, &ft_level, &ctx);
ID3D11Device1* dev1;
dxhr = dev->QueryInterface(__uuidof(ID3D11Device1), (void**)&dev1);
dev->Release()
D3D_FEATURE_LEVEL ft_level = dev1->GetFeatureLevel()

The d3d11.1 objects are valid and working, but I can't use any d3d11.1 specific feature. and the structure for CheckFeatureLevel(D3D11_FEATURE_D3D11_OPTIONS) Returns all FALSE. The ft_level is also D3D_FEATURE_LEVEL_11_0 after fetching from ID3D11Device1.

Is there something I'm missing here ? I'm on windows7 SP1 (with the platform patch), Windows 8.0 sdk and Catalyst 13.9 drivers for my AMD 5950 card.

You can get partial Direct3D 11.1 functionality by installing the Platform Update for Windows 7: http://msdn.microsoft.com/en-us/library/windows/desktop/jj863687(v=vs.85).aspx

The behavior you described is perfect fine. Your hardware/driver combination only supports feature level 11_0 which means you cannot use 11.1 only features.

D3D11.1 is windows 8 only. Some DXGI 1.2 API and the ID3DUserDefinedAnnotation were port on windows 7 too, but most of the functionality are just saying no.
