Hi Cory, In general I'd recommend doing all benchmarking with a system as near to final delivery as possible, so no external tools, definitely no debug build, run with vsync on etc. The OSG itself has some performance stats that you can use, for instance osgviewer has the StatsHandler added to the viewer which you can enable with pressing 's' successively to get different levels of stats reporting.
