just to be clear, it is not necessarily limited to the first frame, it
can happen until all objects have been inside the view frustum for at
least one frame.

sorry, I was not precise on this, it is not OpenSG that moves resources
off the GPU, the OpenGL driver is in charge of deciding what resources
can fit into GPU memory (Texture proxies can give some feedback on this,
but only for textures).
For nvidia (on windows?) there is NVPerfKit that is supposed to provide
information about buffer allocation/resource usage. Perhaps gDebugger
(AFAIK it's free now) can do something similar.
Cheers,
Carsten
