You'll probably get a better answer, but I saw the specs on a forum.
It was running GPL, there were three PCs networked, all were running gpl,
but the left and right pc's were showing live replays using modified camera
angles, giving a left and right peripheral view.
The centre PC was the one doing all the work, the outer two were just
displaying what they saw, so I'd guess the outer PCs would not have to be as
"ninja" as the main one.
