Out of curiosity, what CPU utilization do you see when there's nothing
running on the system?
With some motherboards, and some BIOS settings, we have seen ghost CPU
usage that causes very poor display performance. A bios tweak fixes it up.

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.
