A Google search will reveal that not only have consumers suffered the same problems with this game SWBF 2015, and Battlefield 4 in 2013, but also Battlefield 3 released way back in 2011.
Google those games and any issues you're having to see if there are any working resolutions to your problems, and report back here any that worked for you for others to try.
It seems Frostbite engine games are just not going to work properly or get fixed by the developers, nor is there much help to be had from the publishers. But they will sell more DLC and sequels for you to buy based on the same broken engine, and lock threads for using all capital letters according to forum rules, or tell you the thread is too old and it's "cool" to start a new one.
Not spamming, posting this in threads I've had issues with to let others know to broaden their research to older broken games and not to restrict their hopes to only the most recent broken release's issue reporting.
