Borderlands 3 unplayable after patch

Since the first patch is now released the overall performance should be better. However in some cases this update is better described as a huge downgrade … my fps droped from solid 30+ to -10 at the max. Crashes, freezing and constant lagg after the patch making this game unplayable for me …
Every solution from trashing all settings to low to even prioritising the game in windows didnt work.
Atm im just sad over the start of this otherwise great game.
Reinstalling and hoping the patch isnt forced in my face again (thx epic games -.-) seems to be my only solution for now …
