I am still attempting to run a Cave from a single PC using 3 PCI cards and
Java3D. My PCI cards are VOODOO3 3000s with 16MB on board. I have a
comparison machine available with a TNT 2 Ultra AGP card under Windows NT.
Also, I am using jdk1.3 and J3D 1.2 for OpenGL.
The sample environment is mostly boxes with big textures.
Here are some diagnostics:
If my canvas remains completely on the primary PCI card, things run pretty
smoothly. When I put any tiny part of the canvas on the second monitor,
performance goes way down on BOTH SCREENS. This situation is not rectified
when I remove all objects with textures. Even with 4 simple cubes,
performance is totally whacked when I crossover to the second screen.
I am assuming that I no longer get hardware acceleration when I have any
canvas on the second or third monitor. John Wright had sent an email
warning that this might be the case. Could this also be a limitation of the
PCI bus? Would moving to Direct X offer any solution? If one used one AGP
card and one multimonitor PCI, for example, how would that affect
performance?
As always, thanks for the help.
