For the majority of gameplay, the game hits its 30fps cap and delivers a crisp 1800p image, achieved via checkerboard upscaling and delivering excellent image quality. However, what's clear is that stability in performance is an issue, with the game tearing and dropping frames sporadically during city traversal, while the base PS4 game runs without issue. Police pursuits ramp up transparent alpha effects which clearly exacerbate the problem - surrounded by squad cars with a helicopter search light illuminating the scene, Pro drops frames badly and introduces screen-tear when, once again, the standard PS4 retains its 30fps cap.
Again, the concept of the top-tier console producing sub-par performance isn't really acceptable and it's dismaying to see results like this. The bottom line is that Pro users with 1080p screens may well get a boost to image quality via super-sampling, but reduced performance under any circumstances can only call into question the whole point of a more powerful console.
