The settings on the Graphics Display Options dialog are used to enhance the visual result of your model view. For example, when creating a model in real-time, using the Realistic visual style, you can enable Ambient Occlusion to give your model more realistic shading and depth. The Graphic Display Options dialog is accessed from the Shadows On/Off tool on the View Control Bar.
