Looks like the huge negative blowback from developers over the previous no-DX11.1 for Win 7 forced them to rethink.
Time to start adding DX11.1 to my project!
Hmm looks like I can create a DX11.1 device, but it only supports DX11.0 features.
Guess we will need to wait for an updated Windows 7 driver that implements the DX11.1 features.
AMD just told me that no DX11.1 features are supported on Windows 7 (even if chip supports it), only the API has been ported but you can't actually use any of the new functions.
