Paul,
1)
I have Caligari. It was loadedon my mcahine for a week wehn I got it back
in Mar of 1992. It was so wimpy (no IFF mapping, no deform….) and I
didn't want to fork over big bucks for the broadcast version so, there it
sits, in its box collecting dust.
I think you misunderstood. On the '030, the FP lightwave runs faster than
on the '040. If I use the Integer LW with the 040 I can run as fast as
the '030 did with the FP version. Bottom line – except for meanial tasks
likes reading/writing disk files (low frequency task in rendering) your
'040 is only as fast as or a little slower than your '030 card clocked at
the same speed. WHy? I suspect the '040.library, which I now realize is
CBMs – no need to say more. As for the new LW, I've now got seversl
sources who independently tell me that I will see about a 30% increase in
rendering speed with the '040 over what I get now. WHich in my system
translates to rendering as fast as the '030 in FP mode again. I go back
to my statement that the '040 architecture is not suited to graphics work
(what I wanted the speed increase for) and I would recommend that people
doing graphic/3D/Video work think loong and hard about '040 for that type
of work. And at this point I think I might even advise that they get a
Zues as they would be able to get more freely available and cheaper memory
for it, its cheaper, and I've been told (though no onw has offered tests
to prove it) that it runs rings around the G-Force (but then I was told
the G-FOrce would give 2x-10x increase in rendering time so…). I'm not
trying to be nasty, its just that the serial port doesn't work with the
only term program I use most every day, the cpu does not offer any speed
enhancement for animations without kludges and then it comes UP TO the
speed of a '030 or on a simple scene can sometimes get 20% better on
slected frames. It really didn't turnout the obe worth the $1000 and 4
days of install/deinstall/reinstall/reconfigure to get it working
reasonably well in my system.
2) Good!! Thanks! I hope Steve is able to nail this puppy. It must be
something subtle, but pervasive and I don't think he could find it even if
he tried unless he gets some HW to check it out on.
I appreciate your efforts in this matter, but I think it is a combination
of me using a hammer for a screwdriver after listening to wild calims of
the hammer vendor. '040 with CBM's lib is just not a suitable cpu for
graphics.
