Every time I join or create a coop game for a quest, I get terrible stuttering. My fps stays consistently at 90, and the camera and cursor move smooth, but all units, and the entire actual world stutters endlessly. The only thing I can think of is that my wife, not being at home at the moment, has very slow internet, and that this is some kind of way to keep our game in sync. The problem is that it is unplayable for me.
Just curious if anyone else has run into this.
