Click the Graphics tab of the Options dialog to enable hardware acceleration for improved display performance. On this tab you can also configure colors for selection, highlighting, and alerts, and enable anti-aliasing for 3D views.

Graphics Mode

Use hardware acceleration. Some of the benefits of using hardware acceleration are:

• Faster display of large models upon refresh.
• Switching between windows of views occurs faster with 3D graphics acceleration.
• Creation and modification of annotations is faster.

Colors

Select Invert background color to change the display of the background of the view and the elements in the view. Click this and apply to see the background change to black from white.
To define a new selection color, click the color button next to Selection Color. This option sets the color for items you select in the drawing area, either by clicking on them or using a pick box.
To define a new highlight color, click the color button next to Highlight Color. This option sets the color of highlighted elements (when you move the cursor over an element in the drawing area).
To define a different error color, click the color button next to Alert Color. This option sets the color for elements that are selected when a warning or error occurs.

Just leave these all as they are.

Appearance Quality

Use Anti-Aliasing for 3D views
When enabled, the quality of lines in 3D views is improved. For example, edges display smoother.
