not directly, as OpenSG does not have an explicit render loop or thread
that continuously renders the scene.
That being said, the RenderAction keeps track of the time required to
traverse the scene (and build the draw tree --
DrawActionBase::statTravTime) and the time for drawing the draw tree
(RenderAction::statDrawTime). From the sum of these two times, you can
compute the framerate.
Take a look at one of the test programs in Source/System/Statistics to
see how the statistics component can be used.

There is a loader for .ply files in Source/Contrib/PLY. It is not a full
part of OpenSG because of license issues; see the readme in that
directory for more info and build instructions.
Hope it helps,
Carsten
