frameInterval
The number of frames that must pass before the scene is called to update its contents.
Declaration
var frameInterval: Int { get set }Discussion
The default value is 1, which results in your game being notified at the refresh rate of the display. If the value is set to a value larger than 1, the display link notifies your game at a fraction of the native refresh rate. For example, setting the interval to 2 causes the scene to be called every other frame, providing half the frame rate.
Behavior is undefined with a value less than 1.
