They should probably change the title of the article. I never saw the original one and I thought that the new update added stutter, which isn't the case. Something like, I don't know, "New update fixes stutter on PS4" might have been a clearer title.
This game is so beautiful. The Pro version offers a higher resolution (checkerboard 3072x1728 imagen, then upscaled to 2160 p, over the 900p base PS4 version). The resolution bump is clear, but the checkerboarding artifacts can be quite visible in some cases.
