On the Display page, Primitives area, select the Enable Parametric Primitives check box. The level of detail
changes during navigation depending on the distance from the camera.
If you want to use the default representations of primitives, clear this check box. The level of detail stays
the same during navigation.

If your video card supports OpenGL, you can improve the graphical performance by turning on hardware
acceleration and occlusion culling.
Using the hardware acceleration usually gives you better and faster rendering. However, some graphics cards
may not function well in this mode in which case switching this option off is recommended.
Occlusion culling can significantly improve performance in situations when much of the model is not visible.
For example, when you walk down the corridor of a building, the walls occlude most geometry outside the
corridor. Other rooms are only visible through doorways or windows. Turning on occlusion culling dramatically
reduces the rendering load in such cases.
