The fact the OSG frame rate drops when other threads are hogging the

an issue of OS scheduling of threads, if it does it well then you
shouldn't see threads hanging completely, if it does it poorly then
you'll see what you

Depending on our hardware, the viewer may run in multithreaded mode, which

While using OSG version 1.20, I was taking screenshots with the following

I also noticed this behaviour when loading a .OBJ file containing a single

might be done so for performance reasons.

The Canvas class derives from wxGLCanvas, and is the glue between the

Canvas::GraphicsContext derives from osgViewer::GraphicsWindow (pure
