Hi, until there is an update that fixes the issues the best we can do is make sure that our end is right.
I'm running on a PS4 Pro on Boost. I rarely get freezes or crashes & am only encountering the usual bugs, & not too many of them! Loading in an area is slow, popin is regular, as is lag when in Combat. But otherwise a quick restart or cache clear has solved most issues.
I would advise everyone to check their end (maintenance/updates etc) as a lot of issues are caused by an overworked processor. The fans on the PS4 are on max most of the time!
