For people that having problems with playing custom online games and allways get lost connection. Since f1 2011 came out i have tried many times to play races here on RD and only been able to do one race fine all the others allways get lost connection. I have a Killer Nic 2100 card and for some reason the TCP No Delay was not on, i turned this on and now everything is fine no more lost connections i have turned it off and tried just to make sure and the problem comes back, so the problem seems to be for some people is the TCP No Delay on 0. Here is a link for anyone that wants to try this on utube shows you how to do it, if you have a normal network card. For those that have a killer nic card just tick the TCP No Delay box and reboot.
