Hi Tim, As a general guide I would recommend picking the simplicist way to implement a solution first and it perform fine then stick with it, don't worry too much about performance. Times to worry about performance are when you've already established a bottleneck through testing and now need to address it, or that you know you are about to throw 10's of thousands of objects at the scene graph and need to do it most efficiently.
In your case a simple HUD won't take either the CPU or GPU and an osg::Switch and associated update callback are very unlikely to provide any type of bottleneck. Robert.
