Members

	Member name	Description
	Default	Equivalent to setting One.
	Four	The driver waits for the vertical retrace period. Present operations are not affected more frequently than every fourth screen refresh. Check the Caps.PresentationIntervals property to determine whether the driver supports this option.
	Immediate	The runtime updates the window client area immediately, and might do so more than once during the adapter refresh period. Present operations might be affected immediately. This option is always available for both windowed and full-screen swap chains.
	One	The driver waits for the vertical retrace period (the runtime will beam trace to prevent tearing). Present operations are not affected more frequently than the screen refresh rate; the runtime completes one Present operation per adapter refresh period, at most. This option is always available for both windowed and full-screen swap chains.
	Three	The driver waits for the vertical retrace period. Present operations are not affected more frequently than every third screen refresh. Check the PresentationIntervals property to determine whether the driver supports this option.
	Two	The driver waits for the vertical retrace period. Present operations are not affected more frequently than every second screen refresh. Check the PresentationIntervals property to determine whether the driver supports this option.

Remarks

This PresentationIntervals property of a Caps uses this enumeration.
