I don’t have any noticeable fps slow down anywhere; never have which is odd because in FO4 certain places/situations had noticeable fps issues.
Seems like FO4 waits whereas KCD moves on but some bits lag. With (vanilla) PS4, hoping pop-ins return to 1.5 or better and that the improvement in rain can be tweaked a little more (slight pixelation in heavy rain). If had to, could live with pop-in performance I had with 1.5 and rain pixelation with 1.6.
