I don't know exactly what the bottleneck would be, or if a problem should
occur in a pfGeoSet with more than 64 triangles. But I have run with up to
180 triangles without any problems. And this was only on a little O2.

pg 591 states that a pfGeoSet should not be more than 64 triangles long.
Why is this? What would happen if you exceeded this number? Say you had
15 primitives and your primitives were tristrips of length 50 or so...
what could be expected?

What part of the graphics hardware is this going to cause a bottleneck
in? I am really only concerned about high end systems (OnyxII, O2000)
with IR,IR2,or RE2 graphics.
