I have searched for answers on this and cannot find any, I have made several maps (and used others) and they all run smooth as silk in SP and in the preview mode. The minute I get into Multiplayer the FPS is down to below 15 and it is very choppy. Why is this? I don't understand. I am hosting on ADSL 7 Mbps, which is definitely enough for the 3-6 people I am hosting. What gives guys. Can someone help me out??
