Loss of fps with UE5 update Ready or Not

Before the UE5 update I was running the game with a mix of highest/high/medium settings and getting anywhere from 90-110 fps comfortably with hardly any dips. The game looked gorgeous and was smooth to play. I played so much last summer and unlocked the Developers Ruined Watch and got the achievement for completing every mission with an S. Got a bit burnt out so I didn’t play until the new year. After launching the game for the first time in half a year I was scratching my head as all my settings were reversed to default and no matter what I did I could not get more than 60 fps in game (even on the lowest possible settings). I didn’t even know at the time that there was a new update for UE5 until I searched up on Google why I had shit fps all of a sudden. Only in the police station I could get 80-100 fps. But when it came to a mission, 40-60 and it’s borderline unplayable. So I just wanted to know if anyone has any recommendations or a possible fix, as it stands the game is just not enjoyable at those frames.
