No they did the right thing to remove supersample. Supersample cause this performance issues. This is aga 1.31 version with HDR.
After testing with both supersampling disabled and enabled via system settings on ps4 pro I can confirm that running in 1080p is solid. The 4k mode is what is causing the horrendous pop-in for 1080p users, visible mostly in trees and it isn't limited to this issue as cut-scenes are affected in some way... allow me to iterate on this: during the cutscene when you're tasked with finding triss in Novigrad a soldier began to ragdoll move in and out of view and again during the final cutscene after eliminating the rat infestion with triss she still had a fireball in hand while talking to Geralt. I haven't yet experienced any of the graphical errors while in 1080p and the framerate is solid so I'm sticking to this mode until 4k is fixed, as should all 1080p users.
