Massive stuttering after 'Air Superiority'

My game started to suffer from FPS stuttering after the most recent update.
I’ve never had this issue before, does anyone know a way to fix it?

Hi there!

If not already, please do the following and see if it helps:

  1. Clear the game cache
  2. Verify the integrity of the game files
  3. Disable custom content

if you got nvidia gpu try to down grade drivers to 546.33 it worked for me
