At the most basic level, you're getting a native 4K version of one of Xbox One's most technically accomplished, visually arresting titles, backed up the high-end texture assets previously exclusive to the PC version of the game. Texture filtering gets a big upgrade over the standard console too, with none of the improvements having any kind of noticeable hit to performance. Gears of War 4's campaign did a great job of sticking doggedly to its 30fps target on base hardware - in addition to the big visual boost, Xbox One X hands in the same performance level point-for-point, based on the three campaign levels available to play through.
