Just a quick update for those who still may want to look around the world. It looks like you can fight, craft, etc. without lag but there are no AI in atm. Soooooo you can't craft armor or items that need animal skins. You can however wander around the world and take in the sights
I will make another post once the AI is back if the lag is gone. SV is working on it but as stated before the game is in beta and will still be a good few months away before it reaches most players expectations.
