No not really as I said Rage ran 1080p60fps on PC and x360 well pc due to power and x360 due to eDRAM ps3 version was 30fps because of lack of embeded ram. So yes xbox would benefit a lot from it but end result would be probably same as ps4
Your mistaken there, Rage is 60fps on both consoles and has a variable resolution of between 640x720 and 1280x720
