Hi Paul, In all the OSG 2.x series the DataVariance is used during the draw traversal to monitor when all DYNAMIC StateSet and Drawables have been dispatched, as once they have been the next frame can be started in a parallel with the remaining STATIC objects are rendered (in DrawThreadPerContex, CullThreadPerCameraDrawThreadPerContext threading models.)
