Performance Options
Controls updates of construction history, locators, trim surface boundaries, and expressions. These controls determine when updates occur to these items: construction history, locators, trim surface boundaries, and expressions.
Performance Options settings
After Modification
(Applies to locators and expressions) When After Modification is OFF, the display of updates is suppressed. When set to on (the default), updates are displayed as they happen.
During Transform
(Applies to construction history, locators, and expressions) When During Transform is on, updates occur as you drag the mouse in any Transform operation (such as Transform > Scale). When During Transform is off, updates occur when you release the mouse after an Transform operation. By default, it is on for locators and off for expressions and construction history.
During Playback
(Applies to locators, expressions, and trim surface boundaries) When During Playback is on (the default), updates occur for each frame during playback. When it is off, the updates occur at the end of the playback operation.
Note that: Even though construction history can update for each frame of a playback, it may not do so for a rendering of a playback because SDL does not support all construction history operations.
Trim Surface Boundary Updates
When trimmed surfaces are animated so that their shape changes, the system slows down. You can speed it up by turning Durning Playback off. When trimmed boundaries are disabled, trimmed surfaces only display their interior curves, not their boundary curves, which improves playback performance. This improvement is only apparent when the trimmed surfaces are being deformed. Animation at the transformation level does not benefit from this optimization.
