u/Ejuje

I decided to update my Windows to w11 and the only mistake I think I had was doing it over w10 instead of just factory reseting my whole pc. The instant i tried my games the performance was like 60% worse.
FC24 ran like 140/160 fps and now its below 60
LoL its running at like 70/80fps, not even a 100 (with w10 it was like 240fps)
I tried everything I think I could: Updated my BIOS, updated my chipset drivers, my GPU drivers, repaired my C: disk, tried all of those "how to optimize windows" vids.
Also, I noticed its just the CPU performance that got a LOT worse, GPU dependant games like RDR2 run at normal framerate.
What can I do or should I just go back to Windows 10?
-My PC specs are:
Ryzen 5 3600
16gigs RAM (only one module)
Nvidia 2060 super
