Huge Lag issues on PS4

When this sort of issue happens the first thing I would suggest is to check your Multiplayer Portal controls to see what region is currently set and what your Ping value is for that region.

I usually connect to North America East and there have been a couple of occasions when those servers have gone "Unavailable" and the system just started placing me in any old game session on any old server region, some of which had higher latency issues than others.

If your chosen region hasn't gone down for some reason and the Ping value is reasonable, the higher values indicating more latency problems with 130 being the rough threshold for game breaking experiences, then the issue probably exists elsewhere.

Most people don't realize but there could be an issue somewhere along your connection which is entirely out of your control- anything from your bandwidth actually being shared among your neighborhood, so more people doing data heavy things online slows down everybody, to problems a longer distance from you. There's also, or course, the possibility that the EA servers are experiencing some sort of issue or lack of server resources which affects the players connected to those servers.

I played myself for a good chunk of the day on the game connected to North America East and did not experience the type of game breaking lag that you describe so it may have either been something localized or something affecting the particular region or server you were connected to at the time.
