Tweaking community for 10 is a lot more mature too.
In what sense?! More than 90% of all Windows 10 tweaks apply to Windows 11 as well. After all, for most part - Windows 11 is more like a Major Feature Pack - than a New Operating System. If anything, beyond the newish GUI (visible mainly on the surface - cause some stuff it's still easier change/tweak - while using the old GUIs from older versions of Windows - even Windows 7 not to mention Vista - yet, other settings like a Custom Power Plan, Services, Device Manager, Advanced System Settings, Group Policy, etc... don't even have a Windows 11 GUI - so the older versions is the only option) - to make it look or feel like a Newer OS - Microsoft went with "the restrictions approach". "Officially" - that is. Cause most of those restrictions can be Disabled with basic/simple tweak - allowing oneself to install it even on a 10 year old PC. Not surprisingly, it even runs great - if it meets the "practical/physical requirements (good enough CPU + GPU and enough Ram - preferably using an SSD)". All things consider - the naming of Windows 11 (instead of calling it a major feature pack - as they did in the past) - is purely a marketing gimmick. As in: a renewal of their contracts with every major OEM - which would involve new Windows 11 licenses - for all the millions of new systems released after Windows 11. Microsoft even got them by the balls (so to speak) - since they could have recycled their Windows 10 licenses - yet, they felt compelled to go with the times (looks are everything in the corporate world - or at least that counts to a large extent).
That being said, it's truly baffling - that so many Windows Users - don't really get this part (what Windows 11 actually is). At least from their actions and reactions - there's way to many who treat/see it as a major rework - as if Windows 10 is Windows 98 and Windows 11 is Windows 7 and the changes (new stuff) is compelling (to much to take it all in). Which objectively speaking - is obviously far from being the case. Personally, i was actually waiting for a rework (after their last announcements regarding their intentions with Windows 10 - only a complete rework from the ground up - made sense for a new Windows release). Yet, instead - we got another major feature pack. And all the newbies started freaking out about it. Cause if, instead - they'd just call it a major feature pack - they'd treat it like the rest (complain about performance issues if that was the case - and wait for a fix or revert to an older build for the time being).

13th gen CPUs issue As I mentioned, Biostar may never allow you to disable Undervolt Protection. Intel would like it if all motherboards enabled UVP and disabled undervolting. If being able to undervolt your CPU and run it 20°C cooler is important to you then I would return your Biostar...

ThrottleStop works for your CPU. But it's a good tool - for pointing out throttle issues (be it power, heat or BIOS features related).
Also, try unplugging the Sound Card (EVGA Nu Audio (classic) - just to see if using the builtin audio chip helps with LatencyMon.
As you're probably well aware - there's systems 3x cheaper than yours even older - which don't encounter any such issues under Windows 11 (running smooth like butter - so to speak). I say this - while using such systems right now. Tho, also from my experience with other systems - on which i either installed or tweaked their Windows 11 (even laptops without a dedicated GPU - using the mediocre iGPUs from Intel). Point being - it's clearly not a Windows 11 issue (performing that bad in general), but a specific issue - which for whatever reason (and this is the important part - what one would try to find out while troubleshooting your rig) - didn't get triggered on Windows 10. But hey, since you're trying to solve this issue yoursel and patience is maybe not one of your strengths (don't mean this as a judgement - since there's also lots of games who couldn't care less about the OS - but running their favorite games ASAP on their newly bough rig) - sure - use whatever prove to be working (install Windows 10). I mean, neither of us getting paid for support - we're just playing the role of a good sanitarian - so it's all up to you. The only thing someone like myself can get out of this (which can help for future reference) - is some troubleshooting info (something that could help others - who will ran into same issue). But that - only you find the cause which in turn could also point out to the solution.
