I've been having problems with consistent lag while playing multiplayer and there doesn't seem to be too much help with it. People are saying to open ports or not needing to open ports so I'm not sure what to do. My Internet kind of sucks but I can play all my other games just fine with slower speeds than what I have now. I have about 40 ping, 1.5 mb download and .5 mb upload. Anyone have an idea of what I can do?
