si_edgey This fixed my issue on 22H2, hope it works for you too.
unfortunelly, it hasn't worked for me 
By the way. i noticed that problem is not at 22h2 version, cause when i try common updates this problem always come. Now i think that problem is in some november updates of windows. I will try to specify defined updation package
Hello! Today i had a conversation with support engenier again. and of course he couldn't help me. But he gave me advice to use "Feedback Hub App" - it is kind of support. BUT with engeniers and it is more about technical problem. Support agen said that in this app ansering is more quickly and there are more technical specialist there. I do not know - is it true or he just wanted to push me with my problem to other department 
Anyway, we should use any posbibility to find any help. so i created a feedback there. You can support me there or just see what it is https://aka.ms/AAizv23
https://ledstrain.org/d/2026-w11-kb5020875-update
Try to see if the update number KB5020875 is installed. If yes, uninstall it and reboot.
I am still on W11 21H2 enterprise but the update that destroyed my perfectly working setup is the one there. If I uninstall it everything comes back perfect, but company policies force me to update every day so every day I have to uninstall it.
Oh boy, and to think that I was going to do this update earlier today 
I just received solid proof that guardian angels exist - one such must have saved me from inflicting this upon myself……
Unfortunatelly, i cann't catch update, that break my perfect expierence. This is kind of the "shadow" updates, cause i don't see it in journal, and cannot to delete it. Now i use windows update blocker. but it doesnt help to me(cause it seems like no updates were installed) Something changes in my syste without any traces. I have no idea what it could be and how can i define it. I just reinstall windows every day when i need my computer But i think i cannot live this wy for a long time.
Anyway, i am absolutely sure, tht this started on end of october- begining of the november 2022. Maybe this fact would help to discover this problem someday
arturpanteleev did the BIOS or VBIOS update? maybe an application itself is updating like Chrome?
ryans No. i checked bios. it has old version. This is defenetly something inside windows. But i couldnt find any traces. It is very strange - i checked eventvwr - and i didn't find any install or updates events. It looks like fucking magic. Some people say, thath DWM could be the reason - but it couldnt be updated without any traces. Very very strange things.
Now i gonna try win10. maybe it hasn't this kind of "shadow" update
OK, I'M GONNA SAY IT AND YOU'RE GONNA HATE ME, BUT HEAR ME OUT 
I did a back up and went to Win11 22H2. Also went for the latest NVIDIA GameReady driver version which is 527.56
IT IS FUCKING AMAZING!!!! Can't even compare to Win 11 21H2, it blows it away! The 3D effect is gone, the slight shimmering on letters is gone, colors are vivid but without plucking your brains out all the time.
I played PUBG on 165Hz for SEVERAL HOURS. Several Hours bruh… do you realize what that means?!?! It means this is the "HOLY GRAIL" driver and Windows version combo for me!!! I can recommend anyone with NVIDIA RTX 30 series GPU try that combo (but not before they make a back up of their working setup)!
I immediately did an image and tried all ways possible to stop Windows Update and managed to stop it so far.
The things that helped me to stop Win Update are the following two:

Good luck gang! I came to realize it is NOT the display/monitor at fault. IT'S ALL SOFTWARE AND RENDERING! It's all how the f-ing OS/software draws these frames on your screen!!!
I will definitely be sticking to these two combined - Win 11 22H2, build 22621.963 and NVIDIA GR driver 527.56.
Oshim, great job finding something good for you. On my regular PC, if I force install W11 it will use a video driver from 2016 because Intel stopped updating the igpu driver long ago so I might have a very different experience. I do have a Steam Deck, I should try a Windows-to-Go drive on it sometime and see what happens since the drivers for it are current AMD ones (for RDNA2).
@Sunspark , if you're using an Intel internal graphics adapter, please try Ditherig.exe. It completely removes temporal dithering.
I've tried it on my wife's laptop and it works wonders. Yes, a lot of gradient but who cares when it's good on the eyes.
Someone here mentioned that laptops only go to 266 000 colors or something along those lines and dither all the rest up to 16.7 million. Ditherig.exe completely stops the dithering and I can confirm that it's very nice on the eyes. You should definitely try it with the internal graphics (that's what it was invented for).
Good luck!
Very sorry to hear that :/
What's your monitor's panel? Mine is Innolux (using a Gigabyte M32q monitor). I've had huge problems with LG and AU Optronics panels in the past.
Also, I don't know anything about GTX 1660… I've had a 780 Ti and a 1080 before the 3080 and it did not collaborate well with LG and AU Optronics panels' monitors.
Seems you were correct that with a different setup it will yield different result and unfortunately you had to prove yourself right in a bad way.
*addition to above after checking your monitor
Hey, I just saw that your monitor has a TN panel. Could it be that FRC/dithering is the problem. TN panels tend to be 6 bit and to reach 8 bit color they dither a lot. Could this be the issue with you?
To see if this is the case, please try this in the NVIDIA control panel:
