Hello friends! I'm new in game, playnig for about a week. But all this days I've been chatting with game support, because of low fps. And I cant find a solution to the problem - nothing helps. Fps is about 20, no matter of graphic settings. Even in mode for weak computers. By the way, I'm playing on laptop with nvidia 860m gtx, 2.4 ghz core i7, 16 gb ram. And it is much better than stats in recommended for bns system requirements. So the question is: Is this caused by bad a game optimization? Or maybe i'm doing something wrong and everything is ok on your devices?
