The OSG's osg::GraphicsContext::Traits data structure that is passed
to the osgViewer GraphicsWindow subsystem has a bool vsync that
defaults to true. Under Windows and OSX there is support for enabling
vsync, but alas there isn't any such feature under GLX so Linux etc.
have to rely upon the driver to do it.
I have only developed a couple of applications with OSG, but in my
experience the framerate has been always as high as possible under
Windows. The only way activate vsync for the app is to manually instruct
the drivers to do so. nVidia drivers let you specify that vsync can be
chosen by the app, but osgViewer based apps don't do it.
I've searched the source code to see the effects of
osg::GraphicsContext::Traits::vsync , and I've found that it's not used
at all anywhere, it's just declared and initialized to true, but nothing
more. I don't think that enabling vsync is implemented under Windows, I
cannot tell about OSX.

Hi Robert,
Great! Thank you very much for your explanation! Now, I'm understading many things about
the fps "performace" difference between linux and windows.
Thank you again!
Cheers.
