The number of frames that must pass before the display link notifies the target again.

The default value is
1, which results in your application 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 application at a fraction of the native refresh rate. For example, setting the interval to
2 causes the display link to fire every other frame, providing half the frame rate.
Setting this value to less than
1 results in undefined behavior and is a programmer error.
