looking for a little help here, ever since the most recent patch, my geographic regions for matchmaking is way off. I've contacted my ISP and everything's fine on that end. Any ideas to fix this?
The geographical region depends on the network availability of your ISP.
... unless you have a console or disc that is not from the region in which you are playing. For example, your copy of COD was purchased in France and you are playing on a console in Japan. Won't work.
The geographical location on your System Info is basically where the IP of your connection is based. You need to contact your ISP to have this fixed.
