I almost forgot: the radar animation in jets (and maybe even choppers...?) suggests there is a radar that should show on the map the location of enemy air vehicles (like it did in BF3 and BF4), but I can confidently say that it is a lie and it is not working at all.
EDIT: I've also experienced two PC freezes: it never happened on any other game. Basically, the game starts video-lagging and slowing down, up to the point it completely freezes the PC and nothing will work (ctrl+alt+del, ctrl+shift+esc). It seems random and it never happened since I bought this PC. The first time I've rebooted the PC, the second time I've waited until it BSoD with a screwed up view. Even when looking to Windows Event Viewer, I can only scratch my head to what it could have happened: I can't tell if Dropbox restarting and/or attempting an update is related: maybe the anti-cheat thought it was some kind of malware? I dunno.
