I had asked about this one time and in the end I decided that it was
using 100% of one core intentionally. The run loop is not throttled in
any way, and so I think it will use as much cpu as it can.
Perhaps the nVidia system is better at offloading working or blocks the
CPU differently than the ATI system. In the end, I think this just
points to the CPU being the bottleneck in the ATI system and something
else (video card?) being the bottleneck in the nVidia system.
I doubt that's the case if he's just running cow.osg. More likely,
VSync is not being properly detected on the ATI system, so the viewer is
just running free and not waiting for the frame to be drawn on the screen.
First thing I'd suggest is to make sure you've got the latest drivers
for the ATI card. ATI's OpenGL support has gotten a lot better
recently, so it's possible that a driver upgrade will allow OSG to
properly detect the VSync signal.
