I'm trying to animate a large number of points in Quartz, similar to what is described in this presentation using the 10.2.4 (see slides 10-12):

In 10.2.4, we have movePointGraphic() for this purpose. I haven't been able to locate any similar function in layers or overlays in Quartz.
In Quartz, it seems like Overlays are more well-suited to this kind of thing than feature layers, but I haven't been able to get them fast enough. I've tried using an overlay with a SimpleRenderer in dynamic mode to animate a large number of Point graphics by simply calling Graphic.setGeometry() on each point, and it is too slow.
Is there some trick to this that I'm missing? Among the existing samples, I've only seen examples of updating a small handful of graphics at a time. Thanks for any help on this!
