The Degradation Override button, on the status bar, overrides adaptive degradation so that the active viewport is always shaded, even if this slows performance or causes animation playback to drop frames.
Glossary
Adaptive Degradation dynamically drops the rendering level in shaded viewports, based on display performance. Adaptive degradation takes effect while you work in a shaded viewport transforming objects, changing the view, or playing back an animation.
The Degradation Override button, on the status bar, overrides adaptive degradation so that the active viewport is always shaded, even if this slows performance or causes animation playback to drop frames.
You can set the parameters that control the trade-off between display quality and display speed. The selected levels determine which rendering levels the software falls back to when it cannot maintain the desired display speed. You can choose as many levels as you want, but you are advised to choose only one or two levels for each type of degradation.
Note: When you use Arc Rotate in a shaded viewport while Degradation Override is off, objects degrade to bounding boxes regardless of the adaptive degradation settings.
