flushAt [action] [N]

Controls the rate at which graphics primitives are flushed to screen.
Flushing to screen is an expensive operation so to speed drawing choose an action suitable for your application. Note that detectors are flushed to screen anyway at end of drawing, and events are flushed to screen anyway depending on /vis/scene/endOfEventAction and endOfRunAction.
For NthPrimitive and NthEvent the second parameter N is operative.
For "never", detectors and events are still flushed as described above.
