[AG-TECH] Matrox G200 Drivers Question

One thing that reduced the utilization is to use 16-bit
color rather than 24bit. Aside from that, I have launch my
VIC windows on the G400/AGP card in order to get around the
CPU utilization problem (I'm running a 6-display system with
a G200 and a G400). I'm very interested in any other tricks
to reduce the CPU utilization.

The problem we have been seeing is that as soon as we open 3 windows in Vic, CPU utilization pops up to 50-60%, making for a very unpleasant experience.

Opening 3 Vic windows causes the CPU utilization to run at about 8-9%, which is great. We don't see 50% utilization until we open a lot of windows. Very acceptable behavior. Only problem is that you can't drag any of the windows over to the extended desktop on the projectors - they become corrupted. This is a known behavior and was expected.
