The scenario is as follows: Your Windows 7 (or Windows 7 SP1) system has a DX11 graphics card installed. Click on "View and print detailed performance and system information" in "Performance Information and Tools" (My Computer Properties or Control Panel), where your graphics card is shown to only support DX10.1. Microsoft explained that the reason for this problem is that the performance information and tools incorrectly report the DirectX version, but it does not affect the hardware or software features of the DX11 graphics card, but it is only displayed incorrectly.
For this reason, Microsoft today released a hot fix number KB2461631 (Hotfix). If you are very concerned about this “face problemâ€, you can click here to request a version that suits yours, or you can wait for the next service pack (SP2) to integrate it.
