Use the scene info tab (it's under the "Window" dropdown in DS4) to find out the poly count.
There were a number of reports that DS4's viewport system was slow and laggy on large-ish scenes, so this could be what your experiencing, so instead of using SubD try turning up the smoothing angle on the surfaces instead.
