Hi everyone!
We've seen your reports about lower FPS and stuttering after the September 21st update, and we want you to know that we hear you.
The good news: the issue behind the sudden FPS drop will be fixed with the next update. On top of that, we've spent the past days on a big optimization pass, so the game will run even smoother than before, especially on older and mid-range PCs.
We'll let you know as soon as the update is live. Thank you for your patience and for all your support!
