They didn't miss it. They know it. They just don't know how to solve the problem, so they completely ignore it. Momot said weeks ago that each W3 patch improved the framerate on PS4, wich is an obvious lie. I proved it numerous times, even right in his face. He, of course, never directly replied to these proofs, he just completely ignore them and let the fanboys( eventually CDPR employees) defend the game performances with nonsense.
See for yourself, first post of the page by Momot and my answer 2 posts later : http://forums.cdprojektred.com/threads/56863-LMAO-on-1-08-3-patch-release-note?p=1900215
