Maximum PC: Back in September, Microsoft program manager Daniel Moth indicated during a Q&A session on MSDN that DirectX 11.1 was going to be exclusive to Windows 8, shunning Windows 7 users the same way DirectX 11 initially shunned pre-Windows 7 OSes (it was later made available to Vista and Windows Server 2008). If you were hoping Microsoft would have a similar change of heart and bring DX11.1 to Windows 7, you're in luck.
