Well, the file is gone now because I didn't back it up but the problem was that I deleted the original mesh by mistake and kept the proxy. For some reason mental ray doesn't render the smoothed proxy but the low-poly version instead. So even if the poly-proxy is smoothed afterwards , mr won't render it that way.
