Updates on Performance of Physics Objects with the Upgraded CMS detector for High Luminosity LHC.

This document contains a collection of performance plots obtained with the simulation of the upgrade Phase2 CMS detector for HL-LHC at the centre of mass energy of 14 TeV. Two pileup scenarios with and average <mu> = 140 and 200 collisions per event have been considered. We present updated results compared to the Technical Proposal (CMS-TDR-15-02) and Scope Document (CERN-LHCC-2015-019) for: track, muon, jet reconstruction and btagging performance. In addition, a set of plots containing studies of performance as a function of the linear pile up density along the beam axis are presented for tracking, vertexing, b-tagging, tau identification, muon isolation and missing $E_T$ resolution.
