Before the last game update, the game was running "smooth as silk" on my system with Track IR, CH Pro Pedals, Logitech joystick, and TeamSpeak 3.
I was able to play one session where the frames slowly began dropping until the game came to a near standstill. Restarting the game and rejoining the server I was on corrected this. By the next session, microstutter had manifested, and then the TeamSpeak issue.
Since then (November 28th) the game has been completely unplayable.
