    1809 runs directx9 games at 50fps

    Fresh install of Windows 10 1809 runs some games at 50fps. Mainly directX9 games fullscreen.

    Tried game mode on/off, disable fullscreen optimizations etc.

    Yet, launching VLC player suddenly makes the game go back to 60fps. When I close VLC then the game reverts back to 50fps.

    system: i5 coffee lake, nvidia latest drivers etc.

    The new fullscreen mode may be the culprit or is anyone else having this issue?
