Mouse stutter problem in Bf6

Since the Season 2 update of Bf6, I've been experiencing the so-called mouse stuttering issue. The game is basically unplayable because it feels like my mouse stops sending input every 20 milliseconds. However, the problem is not with the mouse itself.

I've already tried everything I could find online, including disabling overlays, lowering the polling rate, reinstalling the game, and more, but nothing has helped. For a short time, the mouse started working better again, but since the latest update, the game has become unplayable once more.

Is there anything else I can do to fix this?
