We perform an expansion around the upper critical dimension, $d_c=4$, and obtain the critical exponents to one loop order. The main features of the two loop calculation are also outlined. The renormalized theory is shown to exhibit a behavior different from the standard field theory for the DLG with finite driving, {\em i.e.} it is not mean field like.To appear in Phys. Rev.
