It seems to be on par with the PS3 version now. World Map loading times are still longer than they should be, but I think the game is playable for the most part. It still has 30 FPS and the ps3 specific bugs still seem to be there.
I heard the PS4 version is the best version currently, but I don't want to go back to test these versions anymore. I don't think it ever received a patch like the Switch version did.
I personally just play the PS3 version still and only own the Switch/PS4 version because I got them for $20 each and was hoping they'd eventually get patched more.
