Adjusting the AutoCAD 3D Graphics System
You can adjust the performance of the 2D and 3D graphics system in AutoCAD using the Graphics Performance dialog box. To open this dialog box, click the System tab in the Options dialog box and then click the Graphics Performance button in the Hardware Acceleration group.
This dialog box lets you turn on hardware acceleration for your graphic display. If you find that the AutoCAD display is not working properly, you can turn off hardware acceleration. This dialog box also offers control over the way AutoCAD displays 3D modeling features. Note that some PCs may not be equipped with the hardware required for hardware acceleration.
