Using amd's eyefinity it's easy to run the game stretched on two monitors (3840x1080), when the force splitscreen option in local coop makes it perfect for each player to have their own monitor. But currently during combat everything is moved in the center area between the two monitors which makes it rather inconvenient to use.
Please add some support to maintain the splitscreen during combat. This would be really great for people with 2 monitors who want to play with a friend.
I second that, with the first game I used to open inventory and then looked at the second player screen which was obviously very annoying, I don't understand why wouldn't you include that option.
Additionally, even on a single monitor, "force splitscreen" brings a performance penalty, probably something to do with having to render two different perspectives. I wish this could be optimized.
