A bunch of new 4K focused gameplay footage came out today for Rise of the Tomb Raider on PlayStation 4 and PS4 Pro. No, the 4K isn't for the normal PlayStation 4, but you should know that already.
Rise of the Tomb Raider: 20 Year Celebration on the PlayStation 4 Pro will include three modes: 4K Resolution, High Framerate, and Enriched Visuals, allowing you to customize your experience. 4K Resolution displays the game in 4K Resolution, on supported 4K TVs, in 30 fps. High Framerate pushes the framerate above 30 fps at 1080p with a target of 60 fps for an even smoother gameplay experience. Enriched Visuals enhances graphical features of the game for a lusher and more realistic experience, in 1080p at 30 fps.

Rise of the Tomb Raider: 20 Year Celebration is out on October 11 with PlayStation 4 Pro compatibility.

The bold portion of the above is my doing. Take note of the three modes that the game will run at on the PlayStation 4 Pro. It should be noted that there is no option that is 1080p and a solid 60FPS. Let that disappointing fact about the PlayStation 4 Pro hardware sink in a bit.
