/**
|
||||
* clutter_stage_set_sync_delay:
|
||||
* @stage: a #ClutterStage
|
||||
* @sync_delay: number of milliseconds after frame presentation to wait
|
||||
* before painting the next frame. If less than zero, restores the
|
||||
* default behavior where redraw is throttled to the refresh rate but
|
||||
* not synchronized to it.
|
||||
*
|
||||
* This function enables an alternate behavior where Clutter draws at
|
||||
* a fixed point in time after the frame presentation time (also known
|
||||
* as the VBlank time). This is most useful when the application
|
||||
* wants to show incoming data with predictable latency. (The primary
|
||||
* example of this would be a window system compositor.) By synchronizing
|
||||
* to provide new data before Clutter redraws, an external source of
|
||||
* updates (in the compositor, an application) can get a reliable latency.
|
||||
*
|
||||
* The appropriate value of @sync_delay depends on the complexity of
|
||||
* drawing the stage's scene graph - in general a value of between 0
|
||||
* and 8 ms (up to one-half of a typical 60hz frame rate) is appropriate.
|
||||
* using a larger value will reduce latency but risks skipping a frame if
|
||||
* drawing the stage takes too long.
|
||||
*
|
||||
* Since: 1.14
|
||||
* Stability: unstable
