Hello everybody: the freezing problems and fps problems occurs during texture failures. Me and my friends can play after doing following steps: 1. go into video options and disable texture filter 2. log in to a empty server (or server with only some players) and go directly in yout inventory, search for objects, that looks strange, drop them and run away. (You have to take a look in boxes and kits too. After doing this we played some ours yesterday, without problems Maybe this helps for you too.
