One bugger I ran into some time ago, a fluffy ball of dust

resulted in the card speedstepping the GPU and therefore
delivering a pretty disapointing performance.

A saber brush (size 5...)  solved this problem.

Now I do give my machines a regular brush every few months.

This is really weird..

A few things I can think of..

1. In display settings what's the driver listed as on the Boxx? Almost
sounds like it's using the default VGA driver for some reason.

2. Playback can sometimes be more to do with the cpu than the gfx
card. On the Boxx could you try running xsi in a single thread just to
see if that gives you anything different (Goto the xsi process in task
man, right click and set affinity to use just 1 cpu).

3. Are you running multi monitors on the Boxx. If so try just using a
single display.

4. If you say "Hello HAL" to your laptop does it reply with "Hello Dave"? ;)

Regards,
Simon.

 i think i said before.. just about 3 times faster on my laptop..

 so.. say the 100 frame sequence playing all frames takes 6 seconds to
playback on the BOXX (not exaggerating).. it takes a bit over 2 to play back
on my laptop..

 but.. i recently tried an install of the NVIDIA drivers.. by removing the
old one first .. then installing the new one...

 i did it 3 times.. the oldest driver for the card.. the newest... and the
SOFTIMAGE recommended one..

 none of them made one bit of difference (yes.. i also changed the driver to
the softimage XSI setting in the properties)

Well it's very typical to loose proper hardware acceleration after
re-installing Windows and not installing the vendor's driver on top.

also what kind of frame per second are you talking about when you say it's
much faster?

 this one was checked and didn't help.. except making my laptop slower..
made no change on the BOXX

 i was gonna ask the systems guy about Kris' option.. that sounds
interesting.. any other ideas .. please.. keep sending them
