Just FYI, not every PS4 game is enhanced by Pro, and not every game that is enhanced by Pro runs at 60 FPS. For example, Uncharted 4 is the same game but @ 1440p in Pro. Nothing else about it is changed.
Horizon on the Pro did not LOOK like it was running at 60 FPS, and they did not state that it was. The game looked good and was fun, but it was not 60 FPS smooth. I will not lie about that haha.
