Perfomers,

Does anyone have an idea of how much of a performance increase
pfGSetDrawMode(geoset, PFGS_COMPILE_GL, val) will tend to buy you
on the various platforms? I know that objects drawn using OpenGL
display lists display MUCH faster than those drawn in immediate mode
in iR's. Will OpenGL display lists buy you much on Impact graphics,
RE graphics, and on Extreme graphics systems? I was told that
OpenGL display lists should also run faster on Impact machines but I do not
seem to be getting any speed increase with
pfGSetDrawMode(geoset, PFGS_COMPILE_GL, val) on Impacts.
