If you do not see the option to change the Hardware Acceleration setting, your video card may have a specialized controller that you will have to use to change this setting instead, usually by clicking or right clicking on its icon in the system tray.

If the issue is resolved with hardware acceleration turned off, the source of the problem could be old video drivers for your video adapter. In that case, you need to contact the manufacturer of your video card to get the latest drivers.

If you have installed the latest video driver for your video adapter and you continue to experience graphic issues with the Graphics Hardware Acceleration slider set to ‘Full’, try experimenting by reducing the acceleration by one notch and checking the results.
