P1 Gen 2 is a stuttery mess after BIOS 1.56

Recently I updated my BIOS to the latest version (December) and now anything that I use is stuttery. On Windows 10 LTSC and 11 LTSC, everything I do has a little "hickup". But, in CachyOS, its all good and much more smoother, actually.

So, hardware must not be the problem, and I'm certain is the BIOS or something with the ACPI. I tried to rollback to a previous BIOS, but in the manual it says that if you update to the 1.56, you cant go to previous ones.

I don't "essentially" need Windows, but I pay for Office Family, so I would want to use all functions. Maybe the browser options are enough? I'm not certain, but also I didn't want to learn a new Linux while studying for chemichal engineering. Any thing I can do?
