I’m actually doing what you are suggesting for about a month or so now, and i’m also on Nobara!

Today i booted windows for the first time in 2 weeks, just to change the date format as kde wasn’t booting for some weird ansi character problem in the date. Apparently I changed the time on the motherboard and broke something.

That said, i’ve been playing games with basically 0 issues so far (many indies, rdr2 and a copule others) and doing what i usually did on windows.

I still cannot understand the utiliy of tpm, except for tricking tech illiterate people to spend money on a new pc.
