Hi J.P.,
Yes, it happens with all threading models, the only difference being that on
the SingleThreaded model, the CPU consumption is used by the main thread
instead.

Hi Kim,
What does everyone suggest the way for me to make progress the fastest
would be? I'm assuming I will have to send them the system specs of the
systems that are affected, and the minimum set of files that is required
to reproduce the bug, along with some other miscellaneous

Yes, I tested osgviewer.exe in release-mode with the cow.osg model, and
the problem is always reproducible.
Does it happen with all threading modes for OSG?

I may be able to test it out on Ubuntu on my machine tomorrow.
Thank you for all of the support.

Hello all, I've been seeing a problem with high CPU utilization when

Hi Kim,
The high CPU utilization in this case clearly isn't the OSG, but the
drivers/OS.
Try a different OS/drivers. Also once you home in what combination causes
the high CPU utilization go pester NVidia about there driver doing a
spinlock.

Agreed, it appears this way. Though, I've not seen NVidia Windows drivers
spinlock
before. Is the problem

Recently I noticed something that might be related as well. The draw
stage of my application seems to be blocking on vsync signal, rather
than the swap buffers stage. It happens on Windows XP

Ok, that's good.
It seems the spinlock is occurring somewhere in the
OpenThreads::StartPrivateAction::StartThread thread, if that helps at all.
Hmm. That
