Alright, so I have a problem I have never found before. I am lagging pretty badly. I really doubt it is a hardware problem, because I can run big maps alone pretty easily, but when I try playing with other people, I get lag. Some of the signs are that I can't see other people's messages in the lobby, only the hosts. I have a new router, but I really doubt this has anything to do with it because with my old router I was lagging once I got a new computer. Can somebody please tell me what to do?
