Control Performance
3D graphics display and memory allocation can slow performance on your
system. Adaptive degradation, performance tuning and memory tuning are
different approaches to delivering the best performance possible.
Adaptive Degradation
Adaptive degradation is a way to control performance of features as you use
them.
With adaptive degradation on, if performance goes below the level you specify,
effects are turned off or turned down in a certain order until performance
returns to an acceptable level. Each visual style sets a degradation order
appropriate for itself, based on a master order that you can adjust manually.
You set the performance level in frames per second in the Adaptive Degradation
and Performance Tuning dialog box. You can also control the order in which
features are turned off when performance slows. For example, if youre working
on your model with a visual style that has shadows and a background, you
can move Shadows and Backgrounds to the top of the list so that they degrade
first and preserve edge effects that you need while drafting.
To set the performance level for adaptive degradation
1 On the status bar, click Performance Tuner.
2 In the Adaptive Degradation and Performance Tuning dialog box, select
Adaptive Degradation.
3 Enter or select a value for the frames per second. Degradation of the
display begins when performance is below this value.
4 Click OK.
