it wont make a difference. if your playing on a modem, then you have a lot of distance to cover sending and receiving packets to the server. try using this command in the console "net_graph 1" without the quotes.
if your fps is low, its could be a combination of graphical lag and latency.
if your send/receive meter is anything but green, its definitely net lag.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
