I'd like to chime in and include I'm also having random stuttering/fps drops with the recent update.
I noticed we both had AMD and Nvidia products
Processor AMD Ryzen 9 5900X
Nvidia 3090 TI
Drivers updated just like yours but i'm running Windows 11
Also tried optimizing download cache, some players suggested deleting configs and reinstalling which I have done but still having the strutter/fps drops.
Hopefully this can help narrow down the issue
