Alright- I got a new comptuter(3.6ghz 2gb ram and x850xt pe) I put doom3 on it and i loaded up multiplayer. all the pings in the list were above 500 (my connection is cable 4mb) I joined one and it was crazy lag with ping 500 and my fps 1-3 constantly and cant move at all. I repeated this above 8 times including joining empty servers and getting same lag. But if i start my own server or singleplayer, i get 100+fps and do fine. I plugged directly in modem- disabled all firewalls- same effect. :\ My old computer had fine running it. why not the new one? I did everything i could. any help?
