Has anyone found a fix to desync in games? (Behind the server feeling)

Hello,
Just wondering if anyone has found a fix to feeling behind the server in games. I see so many people including myself really struggle with it, and it's just at the point where it's near impossible to play.
What I've tried:
Custom Windows/Linux/Regular Windows + Tweaks
Bios Tweaks
Moving houses
Different ISP's
Ethernet/Wireless
Laptop on battery
Multiple different PC's
Probably more but can't remember everything to be exact.
The only thing that has every stumped me about this, is that mobile phones work fine on games, a Nintendo switch and a very old laptop I used to use (well it was my mams but she gave it to me, I no longer have). I've had an older gaming laptop (i7-7th gen, 1050ti) which on first boot into Windows would run perfect, then as soon as you reboot, it would mess up, regardless of whether it was plugged in or on battery, and this was a continuous cycle.
I just don't get what the issue is or even how to fix it. In my current home, I have had 4 different ISPs (Sky, Virgin Media, Zen, Rise (Current)) and not one of them fixed this issue.
I have seen EMI comments about this issue, only thing is if it was EMI, laptop on battery shouldn't be affected, but it is.
I just don't get what else to do.
Linux maybe made things 5% better, but still near unplayable. I would stick to Linux full time, but game compatibility is a different story.
Any help would be appreciated.

What I've already tried...
[*] Various Windows versions + custom Windows such as ReviOS, XOS etc.
[*] All Windows tweaks that exist
[*] BIOS optimized, CPU optimized, RAM optimized. With OC, without OC, with UV, without UV (just everything)
[*] Hundreds of hours of stress testing (everything)
[*] Older driver versions and not installing drivers
[*] Moving to a new house
[*] DOCSIS (3.1), VDSL (17a and 35b) and FTTH (XGS-PON)
[*] Various ISPs (Telekom, O2, etc.)
[*] Various VPNs such as NordVPN, Proton VPN, ExitLag, LagoFast and WARP
[*] Different routers, different settings
[*] Various computers (Intel and AMD)
[*] Various network cards (PCIe and USB)
[*] LTE, 4G, 5G and StarLink
Nothing worked.
What do I think? It's the Internet.
The packets (UDP) do not reach the server in a "clean flow" and/or do not arrive in the correct order (e.g. due to jitter). This means that the game server receives your packages but has to delete them because they don't make any sense.
Example: The UDP packet arrives that reports to your client that the opponent is dead. But the packages with the shots did not arrive (just as an example)
If you want to use VDSL here, you can choose from 1000 different ISPs, but you are always on the German Telekom line (FTTC). I suspect that during higher loads (prime time, weekends, holidays, etc.) they activate a system that makes my ping lower but triggers this "behind the server" feeling.
Then there is DOCSIS (permanently malfunctioning) which actually works well, but is owned by Vodafone. They are not fixing the infrastructure (back channel strengthening for ~7-8 years).
LTE, 4G and 5G seem to be overloaded.
With FTTH XGS-PON it is the worst. The enemies don't walk around, they teleport.
So far only StarLink has worked well, but I can't set it up here because it is obscured but needs 360° visibility.

Hello,
Thanks for your reply.
I would love to say it's internet but I've had so many different ISP's and nothing has fixed it. Also, I've had devices run fine and some have the weird delay, all on the same internet. For instance my mams laptop works well at my current place (it just sucks for gaming on), but my PC and my girlfriends laptop has issues. I even went to the lengths of swapping the Wifi card out of my mams laptop into my old gaming laptop, and even that did nothing. The only common denominator is something Windows based, but I have no clue what it is.
I'm beyond thinking it's Internet based and actually something to do with Windows or the PC's itself. The main thing is I always have this behind the server feeling, there's no times where it's better or worse. The smoking gun is my old laptop would work perfect on the first Windows boot after installing, then you'd reboot once and it would go to being awful, and this was a constant loop. Also one of my old pc's had one boot that was perfect, every other time before and after it went back to being awful.
I just don't know what it could be, really does stump me.

Also 100% its the internet in my case, have you tried Mudfish VPN? The only major difference between Mudfish and all the VPNs you listed is that mudfish is more in depth and gives you alot more options in the case that you can select multiple different single nodes to route your UDP game packets through. The behind the server issue is very prevalent in Valorant for me, some games I become insane and unhittable while majority is me reaction like a grandpa on the enemies' screen while I get ferrari peeked on mine.
Mudfish fixed most of my desync after I set it up correctly. I connect it through a node in Singapore (server I play on, I'm from Cambodia) in which the node VPS company, very important! = has a physical data center in my country. You'll have to do some research about the nodes available to you in your country just as I did. Mudfish is also very cheap as you only have to pay per traffic, and it just reroutes game packets instead of a full-vpn style.
Give it a try guys and tell me how it went. No hurt in trying since we explored every single thing on every forums lol.

u not understand what is EMI.
EMI, it doesn't matter whether your device is running on battery power or plugged into a wall socet. Anything can be a source of EMI, even a laptop running on battery power. It can be internal and external.

No one fixed the problem.
Some guys said they fixed it by moving
Its had to tell if everyone has the same problem , probably not, between liar and people selling fake/placebo things , i don't think we'll ever figure it out to be honest.
So no , no one trully found anything except moving out and it doesn't (apparently) works for everyone..

I'm not sure about this either, cause it's not like I've always had this problem, it's literally been luck of the draw for me. I've had pc/laptops run fine in my house and last house, and I've had ones that feel like I'm delayed in every game like my current pc. It just makes no sense.
