Well you don't notice the nag until you try windows 10 and windows 11 on the same computer. I was using windows 10 for a few years before upgrading to windows 11. I have a modern computer of CPU of i7-10750H and 32GB. And I am using a i9-10900k with 64GB of ram for work.
My point is atleast I got two different computers to be able to tell it does lag on Windows 11. You are lying that you don't feel lag on windows 11 compared to windows 10 since you have similar spec to OP. If he installed windows 11 he is going to feel much more lag than he was on Windows 10.
You know you got it wrong when you got two people stating windows 11 does lag.
I would say nice try, but it wasn't. It's a complete failure. I triple boot 10/11/Mint on this PC. You also have some weird fantasy notions that I didn't use Windows 10 on the same PC for 7 years and that I don't have more than one PC. I believe after 7 years I would notice some kind of significantly higher lag when using 11. Nope. Doesn't exist. So stop lying and making false representations and weird made up assumptions. I mean really. The people that use Linux and hate Windows like there's no tomorrow, actnig like experts on Windows. LOL! Gtfo.
