Re: Windows 7 SP1 RC1 leaked
Nekro is right, that thread he posted has tons of updates that you must request. This update in particular:
KB975243 - The DirectX Diagnostics Tool incorrectly reports DirectX 11 devices as DirectX 10.1 devices on a computer that is running Windows 7 or Windows Server 2008 R2
I requested that one, even though it seems to be cosmetic. My DX11 GTX 480 was showing as DX10.1.
