Same here! A lot of Lag, if I get into a tank, boom, df re-loads from beginning and then takes forever to get logged back in. I have re-installed the game numerous times with the same results. Finally I get back into a game after a full re-install and I am waiting forever to get into a game, well longer than 5 minutes. I get into a game and the mission objectives with the picture comes on. I hit continue and then poof connection lost. Whole process starts over untill I cycle through all the mission objective games. Then I get into a game and there is lag from other players. But this lag is different, it is a delay lag, kind of a short burst of missing time lag.
The only positive thing is the mixed games where you have the Zep and carriers. Those are my favorites. Just do not shoot the Zep if it is dogfight. I really do not enjoy the 5 minute ban, felt like I was back in High School sitting in the Vice Principals office.
The strange thing is, I am now playing games with people I have not seen for a while. I think I may be in some sort of alternate DF Universe!
