There was no file attached.

When I run the performance monitor: processor time fluctuates between 25 
and 35% being static in one place. Still 60fps in the OSGviewer though 
but testing on a Nvdia card now. Can't test the ATI card at the moment. 
That one had the problem -> down to 10fps and up again to 60 in waves. 
Maybe the problem gets exagerrate on ATI because these cards don't handle 
the paging that well.

No noticeable difference on Nvidia
