Hi Robert,
Where do i set vertical sync? Ive been looking for that a long time :)
Do you mean that the user should set it in it's graphics settings in the os?
I know that using osg::Viewer you can set it by pressing 'v' at run-time..

Hi David,
First up always use vsync enabled, this improves visual quaulity and
automatically gates your app so it doesn't run any faster than what you
mointor required, this will also allow the CPU to idle.
