This is a problem present in the first ESF as well, and also in DMZ if I remember correctly, but i havent played in forever. The thing is, when 5 or more TOTAL people connect to a server, it gets VERY laggy. Its done that on all servers Ive been to that host more than 4 people. Even on my server, sometimes people would join and i forget to set the pass, and it gets laggy as hell, even MY computer gets very framy at times. Its just something we'll have to deal with for now.
