DICE created a thread in the official forums where they track the status on several BF4 issues. They call it Top Issues Tracker. They state that many players have already fun with the game but they also say that they are aware of the fact that some players still have trouble with the game.
They list several problems in the thread and there are three statuses…
INVESTIGATING means they are aware of the issue and trying to reproduce the problem.
FIXING means that they were able to reproduce the issue and that they are working on a fix.
FIX LIVE means that the issue is already corrected with any of the latest updates.
For each issue status, they also mention which platform is affected of the problem. To be up to date, you might want to check out the link to the issues tracker in the official forums.
