    BitBlt Windows 7


    using C and BitBlt and friends for rendering I notice that with Windows 7, having
    'Visual Styles for Windows and Menus' enabled, the performance drops dramatically:

    Windows 7 Visual Styles enabled:
    BitBlt 48.5 milliseconds

    Windows 7 Visual Styles disabled:
    BitBlt 1.5 ms

    Windows XP:
    BitBlt less than 0.1 ms

    Any hints about this issue and how I can improve performacne with window 7?
