osgviewer is the basic tool that you should use to measure performance of a 3d model, it comes with compiling Openscenegraph with the '''-DBUILD_OSG_APPLICATIONS''' option, it provides the basic OSG stats interface, FPS/Cull/Draw being the most important ones for the ultimate bearing load of your model on your machine. | |||
If you want to compare models, for consistency, it is better to use a static camera view(default camera angle/pov is fine), with the wire-frame option enabled to measure the Draw for both visible and hidden faces, wait for a perfect moment and press 'c' to capture the screenshot. Also it is helpful to watch metrics as you disable/enable textures. | |||
