I played just a few days ago, and everything was pretty good. Got a couple of semi-laggy servers, but I figured they were in different countries.
But today, I have experienced the worst lag in all the time I've played BF4 (to be fair I've only been playing a month or two, but still). I found a few lobbies with 4 bars, but upon joining I'm shown that there are multiple connection issues occurring. The last game I played had three severe warnings immediately shown to me as I joined in, so I left. Whenever I join a lobby and run a few feet, I am immediately rubber-banded backward. As I watch the game from the game menu (what you're brought to when you die, I'm not sure what it's called) every so often every person pauses at the same time (lag strike, yippee) before moving again.
I am almost completely unable to play Battlefield right now. I have tested my internet connection and connection in PS4, and both say everything is fine and dandy.
Are the EA servers weird right now? Should I try resetting my internet? Should I just try to play tomorrow?
