Should work perfectly fine - the X would render internally at 4k at 120fps and then output 1080p 120fps image to your E8.
Awesome thank you so much! I have purchased both Ori and the Blind Forest and Will Of The Wisps to play, should they be played in order?
I really feel MS should have been pushing this, Gears and Horizon 4 so much harder than they have. To lots of people they are essentially new games, just like Nintendo has done with all the Wii U ports
