According to a reply from an engineer on Microsoft's Developer Network forum, DirectX 11.1 will be available exclusively for flavors of Windows 8 only. There are apparently no plans to release 11.1 for Windows 7 or Vista. "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", the post reads.Although this information comes from Microsoft employee David Moth, it's important to note that Microsoft itself has not provided an official statement on the matter. Having "no plan" doesn't necessarily ensure it won't happen either -- but so far, it sound too good for Windows 7 users.
