Horrible performance with last patch

Issue Description (Required):

My PC specs:

AMD Ryzen 7 5700X3D
GeForce RTX 3080
16384 MBytes DDR4-3200 (1600 MHz) Ram
MPG B550 GAMING PLUS Mainboard

The NVidia overlay says I am around at least 90 fps but honestly it feels like I am always below 30 fps, even in the lobby. Actually it is the first time I see such a difference between the NVidia overlay number and reality.

Attempted Solutions (Optional):

I played with all the video settings, performance does not change.

Platform (Required):

PC - Steam
