#2The usual consensus I've heard is that UAC is always on even after turning the slider all the way off, while using the admin account doesn't use UAC (changing the EnableLUA in reg also works).

#3There was a scheduler bug in the early Ryzen days that got fixed, this will too.

#4The background for this really puzzles me. AMD said you should be seeing more improvement for zen 5 over zen 4. They go back and forth, AMD says run it as super root. Zen 5 gets faster. But zen 4 gets faster too. The improvement basically disappears again when the "fix" is applied universally. So why was AMD testing with two different setups?

Apparently just running the process as Admin works as well

#6Phoronix’s tests of 9950X on Windows and Linux: https://www.phoronix.com/review/ryzen-9950x-windows11-ubuntu
9950X is 14% faster than 7950X on Ubuntu. And 10% faster on Windows.
Ubuntu is 10% faster than Windows on the same hardware.

CachyOS has also put out a repository of packages compiled for zen4/5 [1], which I'm fairly sure Phoronix has shown an interest in doing an updated comparison against the current x86_64-v2/v3/v4/etc versions

#8There is absolutely no detail here. Tl;dr maybe Ryzen CPUs are a handful of percent faster when testing under the admin account instead of non-admin. Is it reproducible? Who knows. What does Windows 11 have to do with it? Who knows. We know nothing after reading the article.

This is the first I'm reading that UAC has a performance impact and I'd like to know more.
I have a PC that I literally use for single player games and nothing else (I do not have a web browser installed, or even Steam, games are installed from a network share). I have no use for UAC and I'd like to squeeze everything out of my CPU.

Is there any good reason for Microsoft to not open-source Windows? They are dangerously close to creating the Year of the Linux Desktop if they continue proving Wirth right.
