Instead of using players’ region as the determining factor for matchmaking on consoles, Black Ops 2 will use players’ latency and ping to decide who to match who up with when entering public lobbies. Your region won’t make a difference. Treyarch’s David Vonderhaar took to Twitter after being asked if there will be a region preference in Black Ops 2. “Not region based anymore. Latency/ping based exclusively”, replied the game design director earlier today in a tweet that seems to have since been deleted.
Black Ops 2′s ping and latency based matchmaking system is still being tested, but if Treyarch get it right gamers should start seeing themselves being put in matches with people who have the best connection to them, as opposed to simply being in the same region and hopefully having a good connection to them.
It’s not know if they plan on using the same system for matchmaking on the PC, but the PC version of Black Ops 2 comes with matchmaking and official ranked dedicated servers, so lag shouldn’t be a problem on that platform. Of course, until everyone gets 100Mbps Internet connections at home, lag will always be an issue to some degree, though.
