Some PS4 Pro Titles Running Slower Than Base Hardware
 

This is really too bad, but apparently developers didn't take Sony's guidelines for consistent experiences between the PS4 Pro and base models as seriously as everyone would have liked. People are seeing dips as much as 20fps in games like Deus Ex. …for games like Skyrim, The Last of Us and Mantis Burn Racing, gameplay will actually be smoother overall on base PlayStation 4 hardware. Deus Ex: Mankind Divided is a little more complicated: we find that some scenes play at a noticeably lower frame-rate, while others hand in more consistent performance overall. For 1080p support, the Pro down-samples the 4K mode for all of these titles, offering enhanced image quality via super-sampling. However, the areas where performance is degraded remain impacted when running on a full HD display - meaning that there's nothing that Pro owners can do to get a smoother experience overall on these titles. In fact, the base PlayStation 4 will run these releases at a higher performance level overall at the expense of some image quality.
