no, there is no such functionality, because OpenSG does not control the
render loop.

... you can use a SimpleStatisticsForeground or
GraphicStatisticsForeground to display various statistics OpenSG
collects. Among them is the time needed to draw all objects, which can
be used as an approximation to the reciprocal of fps. Please take a look
at testStatisticsRender.cpp
Source/System/Statistics/Source/System/Statistics/testStatisticsGraphicsRender.cpp
which show how to set up these foregrounds.
Hope it helps,
Carsten
