    Yes, you really should use v3f on GT, GTX, and VGX machines.  The VGX in
    particular cannot parallelize move/draw syntax commands, and therefore
    performs very poorly on them.  The Personal Iris is unfortunately optimized
    for the soon-to-be-obsolete move/draw interface.
    ...
    v3f calls are the future of the Iris Graphics Library.  If you choose to
    take advantage of the performance advantage of move/draw calls on current
    Personal Iris equipment, you should consider writing your code to use
    v3f on all other platforms.

Will the performance penalty for using the "high performance" vertex drawing
functions on the Personal IRIS go away with IRIX 4.0, or is this embedded
in the graphics hardware of the PI?
