I've noticed problems with network performance in the current build. We often rubberbanded backwards while moving around but in a new way I haven't seen before, with the character 'dragged' backwards. We also teleported backwards about 100 meters instantly a few times. I've attached a video to demonstrate. The server was also slow to respond to actions like eat, reload etc.
This behaviour was noticed on 3 different Australian servers, even on a quiet one. Interestingly when we changed to a US server the problem was much less noticeable (we live in AU).
