I've been a statistical outlier in terms of game stability from the moment I installed it. Since the previous patch, I had the issue where certain maps will sound loop crash on every attempt to play them, most of the time while still in deployment screen. The latest patch fixed it for me, Metro, Dawnbreaker, Paracel and Locker are all now playable for me, no crashes yet, only played a little under the lastest update. My framerate is also improved, at 1440p and Ultra/2XMSAA, I don't dip into 30's anymore unless there are a lot of explosions happening within my view at the same time. Hopefully the next patch won't undo this one for me.
Having skipped BF franchise since BC2 and my online shooter experience largely made of a decade in CS and CS:S, here are things I observed in recent online shooters and community:
-Absolutely avoid communications with random people even if the gameplay suffers. The internet has always been a magnet for idiots but I didn't kbow it was to this extent. My experiences with spoiled brats, trolls and pro complainers has driven me conclude that, if the world ends tomorrow, I'll spend my final moments smiling knowing that these "people" are going too.
-So much disregard for rules and common sense both on end user and the dev/publisher sides. While frag fests on "no explosives" servers and "I'll fly/drive this vehicle without even the basic skills" are addressed in my point above, DICE totally dropped the ball on server customization. Copying the grind from F2P's and feature creep serve as distractions from inability to innovate. I'm not even sure feature creep is the right is the right term, it's rather bloat that doesn't have much to do with the game itself. Lucky for BF others have the same problem and rely on uniform counts, gun attachments and mission assignments too but there is so much to be improved, someone is bound to nail it.
-BF4, when working as intended, is the best online PC shooter at the moment, from a technical aspect yet old CS's beats it in most important aspects of online gun play. It's not too difficult to topple BF from that spot but the way the game industry works sets a high entry bar only few heavyweights can deal with.
