Hello! The team's doing their best, we recognize a huge demand from the community for cleaner textures (and come on, we also want our game to look good). We'll focus our efforts in this direction even more after this update.
Sadly I can't give any ETA beyond "as soon as possible", as optimization works are unpredictable - it may yield negligible increase for weeks or even months, and then a sudden discovery of a large memory leak may give significant improvement. We'll be gradually improving the quality up to what the console can handle with acceptable stability, given the current optimization progress.
Side note: it appears that not all graphics updates are functioning correctly after the patch specifically on PS5. We've discovered why (related to some nuances with backwards compatibility) and we're preparing to enable them in the hotfix. Picture should improve further after that.
