Craig,

not sure if this is relevant for your application, but one way to
accelerate initial rendering (but not always interactivity) is to use
the multi-primitve syntax for Polygon, Point and Line objects.

You could also try to play around with Graphics Options ->
RenderingOptions in the Option Inspector (this can also be done
programmatically, there should be some threads around).

Regards,
Yves
