Supposedly there are no plans for DirectX 11.1 for Windows 7 planned. The question is, is this really a big deal for any of you?
In a recent post on the Microsoft Answers forum, Microsoft employee Daniel Moth stated, "DirectX 11.1 is part of Windows 8, just like DirectX 11 was part of Windows 7. DirectX 11 was made available for Vista .... but at this point there is no plan for DirectX 11.1 to be made available on Windows 7."
