Yep, i have the same issue and i have a 80 mbps internet atm. The issue is the stress test shit. I join a server and you can see in the chat or server info, that everyone is being kicked due to the Battleye: client not responding, message. I don`t think you can play anything other than singleplayer atm. AND if you don`t know what i am talking about, google: 0.63 dayz stress test.
