We report preliminary results on the measurement of the $e^+e^- \to p \bar{p}$ cross section with the CMD-3 detector at the VEPP-2000 electron-positron collider based on 4.5 pb-1 of integrated luminosity collected in the c.m. energy range 1.92 - 2.0 GeV. Event selection using information from the Drift Chamber and Calorimeters provides a clean sample of $p \bar{p}$ events. The obtained results are in good agreement with the previous measurements.
