Hi,

   While trying to figure out why an app runs slow when using
an MCO to split the screen into 3 sections, we've discovered
that our 2 RM machine chokes when the pixel depth is small.
As long as the pixel depth is medium the app runs nicely.

So, we are faced with either using only 2 screens, use 3
screens and buying 2 more RM's or figure out what we can do
to the program to make it run fast enough with small pixels :)

My program is based on multichannel.c example. What kind of
things can I turn off to gain speed? Things that might be
emulated by performer under small pixels, but done in hardware
at medium ?

We are using Irix 5.3 and performer 2.0. The machine is a desk
side onyx , 2 CPU's, 2 RM's , one MCO.

Thanks.
Eric
