Here's my stats. Played from opening day. Have only 4.8 mbs connection. My xb1 lagged...not sure if its frame rate or server lag but holy crap is it frustrating. But even in small battles, lagging out to a DC was my life.random load screens always ended with my character dead, if I came back at all, usually DC'd.. One x not so much. Frame rate or server lag doesn't seem to be much of an issue any more. Random load screens that would last way too long lasts only seconds if they happen at all. i haven't returned to a blue dead character screen... I have experienced frame rate slowing down when there is a huge battle,50-90, inside on pins but its manageable, most importantly you can see who lagged out, xbx1 owners most likely, and those who have an xbx1x are still in the fight.
Getting this 1x in my experience has made this game fun again. Worth the 500.00 clams... worth mentioning, I dont have a 4k TV or settings to support it either... only a 1080p... what's your experience? Better or same for you? Remember compare apples for apples.
