DOA4 network problems...
I'm not sure if everyone knows this or not, but there seems to be some problems with the online play in DOA4. Many times at the end of the match, the game will just freeze. Has anyone had this happen to them? I'm guessing the cause is someone with a bad connection is in the match and it messes everything up. Also sometimes, there will be a person or two online who I can't hear, and they can't hear me, and when everyone is in the lobby, we can't see each other, or each other's stats and that person appears with a F- rank, when they are really. say, a B. But everyone else in the lobby and the match can see and hear the other person, but they can't see or hear me. I don't know what the deal is there, but its very strange, and it can't be my connection, since everyone tells me its always 3 green bars. I hope they are trying to fix this...
That's due to lag, the game is seriously bandwidth hungry, and it doesn't help that it seems to have a bug in there which slows the game down dramatically when there are more than 3/4 players in the same room.
With that in mind though, I was playing last night against quite a few Americans, and I'm in Britain, so I doubt that your connection has anything to do with it, unless it's a slow one. Chances are that it's just the game, and hopefully they will fix it.
Easiest solution is just to play with people you know. I have a lowly 1.5mb DSL connection and I can play against my friends completely lag free, but when ever I play with someone I dont know - BOOM black screen of death.
Yeah, I figure that its the game. I really hope its not my connection, since I only have a 256k cable connection. I can, like you say, play with friends just fine, and most of the time, play with others, but when 1 person with a bad connection joins, it slows everything down...
