Game developers are aware of performance problems
With one of the latest game updates among other changes a lot of players have started experiencing major issues with FPS drops which is critical for any FPS game you play. The usual behaviour of the game developers is to talk to community only via official announces, however some time ago they have hired some people who chat with the community on reddit. One of this guys have commented on the current situation:
I'm sure you guys are sick of seeing me in every one of these threads saying essentially the same thing but... devs are aware and investigating. According to the devs I've spoken to it's actually not clear that this is tied to anti-cheat stuff (could have something to do with a recent server update).
Will share more when I can find out more. I know the most important thing is to get this shit fixed.
