Xbox one X

Other then better frame rates is there any graphics improvements for the One X

I have both consoles and there are no major improvements that I can see, both console will play at 1080p (Depending on your TV). If the horde is too far away from your hero it will always be 30 FPS or less to reduce frame drop. One X has better colour improvements but that's most likely because I have a 4K TV. There are other games that excel with the One X but not DD2.
