FSAA (Full Screen Anti-aliasing) currently causes problems, especially when set to 4x, though 2x can cause some problems in cockpits too, particularly for nVidia graphics cards. Switch off FSAA via your Display Settings menu for your graphics card. Consult your graphics card manual or the manufacturer's website if you have difficulty finding this. Also, uninstall and reinstall your graphics card's drivers, and install the latest version of DirectX from the Microsoft website. If you have "ffdshow" installed at the same time, it might be a cause of a conflict, too.
