Caspian is what I thought it would be, I'll definitely be playing alot of conquest. Having good squads with voicecom on a huge map like that is going to make for many fun nights.
I keep getting disconnected when I finally do catch a Caspian server. I'm guessing that maybe hundreds of people constantly trying to connect to it causes some instability. I did notice weird lag spikes even though the server was 70 ping.
My cores maxed out around 35-40% in the Metro map, but they were hovering around 70% in Caspian. I wonder how much of that is the double player count versus the larger map and view distances. My overall framerate seemed to suffer on Caspian and I'm now pretty sure I'll go crossfire.
