    Direct3D 11 runtime introduces Direct3D 9, 10, and 10.1 "feature levels", compatibility modes which only allow the use of hardware features defined in the specified version of Direct3D. For Direct3D 9 hardware, there are three different feature levels, grouped by common capabilities of "low", "med" and "high-end" video cards; the runtime directly uses Direct3D 9 DDI provided in all WDDM drivers.

    Your graphics card only supports DX 10.1. However, your DirectX version on your computer is 11.

    To know your true DX version, go to Dxdiag and click on display tab->DDI Version. Yours is 10.1, but DX version installed on the computer is 11. That DX 11 is only there as an indication that Windows 7 supports it. Put the same card on an XP machine and it'll say DX version 9.0.

    OTOH, if you believe your card supports 11 and dxdiag is reporting incorrectly, theres a hotfix available to correct that. See this.

    The 5770s are DX11 capable.

    Dxdiag reports it properly for me, but where it shows DX10 for you, I guess that's because the WEI test only benchmarks DX9 and DX10, so if your card can do the DX10 test, it will just report the DX10.

    These DX11 cards reporting DX10 in WEI and DDI of 10.1 are/will be fixed in the release of SP1 for Win7.

    DXdiag incorrectly showing DX11 cards as 10.1 Hotfix

    There is a hotfix around for the DDI in DXDiag.
    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

    Again, thanks for the help and input.

    I applied the Hotfix and now Dxdiag reports DX11. The WEI report, however, still reports DX10. Guess I shouldn't worry about that too much, huh?

    I can't find anything about that for mine either on the net, like I said before, that's the only reason I can think of it happening.
