Zoran,
Try spending about $100 on a new graphics card (such as one
based on the GeForce2 Ti chipset) and you should see much better
results. If that still isn't enough, then try upgrading the CPU /
memory.
The graphics card you have is very old (as far as graphics
cards are concerned), and that may be the real bottleneck. In fact, you
may not be using hardware acceleration if you use that graphics card with Java
3D. As for paging, you may be able to do some things to bring the memory
usage down (400 MB sounds like too much for what you are doing, but it is hard
to say for sure). If you don't hear the hard drive crunching while you
are using your app, it is probably not paging severely.

[JAVA3D] Performance question
Hello there,
I have complex 3D object with about 10,000
quads, no textures - actually the series of
objects, about 20 quads each. Currently it is
running 500 MHz DELL with 280 MB ram and
Revolution 3D graphics card ( from Number Nine
technology) - about 2-3 years old card - I am
even not sure how much memory it has.
When the rotation and or zooming is
performed on the 3D object, the CPU monitor shows
frequently 100% CPU and the object barely moves (
very slow).
Here is the
question: If I upgrade to 2GHz / 512 MB RAM machine,
with, let's say, nvidia 32/64 card
what kind of performance improvement could I expect - 30% or more like 300% ?
I know that it is
hard to answer
this, but if anybody had a chance to perform similar upgrade recently, it
would be nice
to know before
spending $2k on the new machine. I need to speed things up at least few times
... Is there
specific video card
that handles quads better than others ??
The memory seems to go (VR) to about 400MB
used, so I am assuming that some paging is going on
at that time, thus 512 MB ram is what I thought
would help.
Any experience shared is appreciated much
!!
Thanks,
Zoran
