Hi Andrew, Could you convert your PrimitiveSet to a DrawElement and modifiy the index list to remove the hidden primitives? You could then turn off display lists and turn on VBOs such that the driver only needs to send the index list when it gets changed. I don't think OSG supports partial updates of buffers, but you could split up your PrimitiveSet into multiple DrawElements based on which primitives were likely to be hidden or unhidden together.
