Bob,
Have you tried connecting an external monitor to the Toshiba laptop? It
sounds like you are comparing the visual quality of an analog monitor to
an LCD screen.
There are a number of reasons why a laptop might be slower than a
desktop of "equal specs". Laptop hard drives are typically slower,
often a laptop will lag in memory bus technology (might have PC133
memory on the desktop and only PC66 or PC100 memory on the laptop). Or
even something funky like power management that slows the laptop CPU
down to conserve energy and then detects that you want to do something
and steps back up in speed.
It's good to hear Java 3D is flying along with good speed on the
Toshiba. Thanks for the report.
