Accelerate Display Performance
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.
To use hardware acceleration
NOTE: If your video card does not support OpenGL hardware acceleration,
this option is not available.
1 Click the application button
Options.
2 In the Options Editor, expand the Interface node, and click the
Display option.
3 On the Display page, Acceleration area, select the Hardware
Acceleration check box. This allows Autodesk Navisworks to utilize
any available OpenGL hardware acceleration on your video card.
NOTE If your video card drivers do not function well with Autodesk
Navisworks, clear this check box.
