After this update (4.01) the game had a tremendous drop in performance making it almost unplayable on my computer, I hope you take this opinion into account.

Yep, same here I was enjoying above 60fps 1440p on Ultra/High settings and that just been sliced down to more then half.

I hope they fix this ASAP because I don't find this acceptable.

EDIT: Never mind, I'm rolling back to last version through Galaxy and disable auto-update as I had no issues running that one.

Me too. Was doing OK with 60fps on a medium/high setting using a measly 1060... now it`s 45 straight after this post anniversary update as well. Worst still, lowering everything to Medium barely gets 50... WTF.

And then there`s the newly acquired Stutter fps drop enhancement.

Used to play on a GTX 1070 (with consistent 40+ fps) and had recently switched to a GTX 3060TI. Now with the latest update I can't get more than 45-50 fps on Ultra, not to mention RT or RT Ultra where I get at most 35-40 fps. Please fix it.
L.E. worth mentioning is that Cyberpunk 2077 with all settings RT Ultra gets me minimum 45 fps on the same GTX 3060TI. Both games played on 1440p.
