Hi one node callback can be called multiple times per frame if node is shared in several graph paths (and iirc event callbacks can be called once per event happened between frames). If you just need to know framerate - there are osgViewer::StatsHandler. Other than that - you should track frame number (you can get those from nodevisitor framestamp).
