Battlefield 4 continues to have multiplayer issues across platforms even after multiple patches as noted on DICE’s official issue tracker. Players continue to experience problems connecting to servers, random desynchronization, hit detection, drops in framerate, and other errors. A new notice on the Battlog page notes that a special double XP event has been postponed presumably due to the intermittent connectivity issues.
The end of December 2XP event for premium members has been postponed and will be run at a later date. Stay tuned for more information. We apologize for the inconvenience.
The issues in Battlefield 4 have gotten severe enough that two separate lawsuits have been filed on behalf of EA investors.
