Thank you for getting this thread back on track with some new and relevant information!
These kinds of discussions always seem to turn into a confrontational vibe between those who want some technical issues addressed and those who don't think it's that important and (for some reason) get defensive.
The PS4 app in backwards-compatible mode runs at a smoother framerate on the PS5 than the PS5 native app on the PS5.
We just want to know:
a) why is this?
b) can SE acknowledge this and give us a plan/options to address it?
If ambient occlusion is indeed the cause, it would be nice to have the option turn it off.
The frame rate drops are worse than any benefit ambient occlusion provides (in my opinion).
If you play the PS5 version and don't perceive any problems, then you are good to go. The idea behind threads like this is not really about taking a poll as to who is bothered by inconsistent frame rate presentation and who is not. (This comment is directed to the thread as a whole and not the poster I quoted above.)
