Is is as fast if I call a display list within an other display list as putting it all in one list? It doesn''t take more cpu, does it? cause the lists are done by the hardware... Maybe it slows down the hardware? Marty

I would imagine the performance hit is minimal to nonexistant, since the nested display lists would be compiled within the top-level display list. The best way to find out is try it both ways and see if there is a difference in performance.
