To those of you who i know have been having MAJOR connectivity issues (specifically RIDICULOUSLY high ping and a steady 50,000 - 100,000 desync and constant stuttering) since the latest patch/update i have a solution for you. i was running AVG and had tried every solution under the sun, uninstalled and reinstalled everything to do with dayz or steam and nothing seemed to work (not even disabling AVG). My friends recommended i switch to MSE as it is a far less processor intensive antivirus and they ran it and had no problems with DayZ (this is after some extensive research into other people that had this problem) after switching to MSE i am happy to confirm my ping is now down to between 10-20 (from 1000) and desync sits at 0 constantly NO ISSUES. TL;DR Switch to MSE for your security, your issues should go away (hopefully, it worked for me.)
