>I am still attempting to run a Cave from a single PC using 3 PCI cards
and

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

AGP
