So I was playing with a couple other friends on Dune 2000 multiplayer last night with 3 of us total and we were having no lag issues peer-to-peer. Once I tried to have 4 of us total we started to lag bad making it impossible to play. We even tried to have different people host and it still lagged terribly. We all have very fast internet as well. Is there a limit to how many people I can play with on dune 2000 multiplayer before it lags? Or is there a fix so we have 4 or more players in one game without lag? Your help would be very much appreciated. Thanks!
