To Work With Adaptive Degradation

With adaptive degradation on, if performance goes below the number of frames per second (FPS) 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 effects are turned off when performance slows. For example, if you are 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.

Change the Degradation Order for Effects and Objects

1. On the status bar, click the Hardware Acceleration button.
2. Click Performance Tuner.
3. In the Adaptive Degradation and Performance Tuning dialog box, select an effect in the list.
