Great, now i can’t wait for the update. The update still needs to pass for certification for the PS4 
Real-hawk, hazelnus; it improves streaming… for systems that are optimal or standard willnwork way better…
But…
As we will eventually (no doubt) find out- heavily fragmented game installs will still underdeliver.
Feedback so far on steps I gave to improve EACH users installs (where issue is users hardware)… are valid.
Feedback (happening now) is confirming it helps.
So… maybe those steps…
1.make an offfdrive backup of game using consoles backup ability.
2. Clean drive (or delete one or two games from start of drive)
3. Restore backup
Helps.
How much it helps depends on how bad the fragmentation is, obviously… but it will prove a great starting point for playing.
And you can do it right now
But preempting your complaints… (this is a known issue /I shouldnt have to fix it/all ps4 are the same/I have a Pro model-it isnt my hardware)- I have heard them all and trying to show me up to be stupid doesnt help anyone…
Anyhow feedback is in and it will help. Your choice and no, this isnt a problem for sony or warhorse to solve.
Individuals fragmented drives is in users control.
