I have this issue where the dayz application randomly starts downloading data (according to task manager) and lags my game. It skyrockets my ping and I cannot use anything in my inventory at this time. My direct chat works fine however and is not laggy. On other people's screens my character moves perfectly normal, but on my screen all characters and zombies are stuck in place. My character has not died since the last character wipe.
*EDIT* Discovered the issue. My character had corrupted items on him due to how long he had been alive. After I dropped all my old equipment on the ground it solved the issue. I don't know much about the dayz netcode but it's possible the corrupted items were causing some packet loss, which would give me a high ping and desync.
