I have a 50k line everything works on the ps4 very good except fifa online jerky I've tried so much we still have the television box of 1und1 pulls the really so much internet?
Go with the ps4 settings at "Internet connection test" and play it for a while… Maybe that helps against your Laggs.
I would be glad about an answer, if it worked
Unfortunately, I've done that several times before
Mhm pity.
