In the Graphics area, check or uncheck the Hardware Acceleration check box.
Click OK.
Hardware Acceleration increases the speed of your graphics display. When Hardware Acceleration is selected, your computer takes advantage of any installed graphics card that supports hardware acceleration. If no card exists, and Hardware Acceleration is still selected, your computer automatically defaults to slower software acceleration, which uses the Windows implementation of OpenGL.
In most cases, it is best to enable Hardware Acceleration. However, problems sometimes arise with graphics cards on which hardware acceleration is poorly implemented. If you are experiencing display-related problems like scrambled line patterns, you should clear the Hardware Acceleration check box.
To enable or disable hardware acceleration:
Select Settings
> Program Settings or click the Program Settings button on the
Settings toolbar.
In the Program Settings dialog, select the General tab.
In the Graphics area, check or uncheck the Hardware Acceleration check box.
Click OK.
