@RockDokRockAside from the 60fps vs 30fps difference as Hayhor mentioned in all honesty graphically I don't see any difference it's a PS4 port after all.It's a shame that Respawn hasn't provided the next gen upgrades (PS5/Xbox X/S) like most other multiplayers have benefitted from & although they have mentioned the upgrade is in the pipeline that could mean anything (next month,next year,next decade etc).One benefit between playing Apex on PS5 over the PS4 is the controller & although the PS5 is a little heavier,feels a little clunkier & sticks feel a little more sensitive I still feel the PS5 controller is far better once you get used to it.Re-configuring your aim/alc settings to suit is a wise option.PS5 is a worthy purchase but as I mentioned in another post the biggest issue I (& many other people) have with is how small the HD capacity is which is a little under 670GB once online bits & bobs have been taken off & can get eaten up in as few as half a dozen games.
Server issues have still been as problematic on the PS5 as on the PS4 so no difference.
