Well, played the beta and I've never had so many disconnects, ever. I get disco'd once every 10-15 mins, sometimes more and more, never less. I've tried to search for the problem to see if there's a solution but searching for Disconnect or Disconnected from server, yeah, search for it and see what I mean.
I'm in Windows 7, gigabyte mobo, amd proc, ati card, 2g ddr2.
Like I said, I didn't have these disconnects during beta. I'm quite disappointed at the the state of the game.
