This sounds like a C3/C6 sleep state issue.
Have you tried playing in (limited) natural light, to exclude the effects of lighting issues? Fluorescent lights in particular do flicker; so do many LED lights. You might be experiencing sensory issues due to the almost subliminal flicker. That is, that the jitter you observe isn't in the hardware, it is in your perception.
In particular, if you have "ambient" LED lights behind your display, those often suffer from flickering issues.
There are two things that can affect your PC performance:
1) air with different humidity has different thermal conductivity, so it leads to different cooling efficiency
2) air humidity depends on environment temperature, higher temperature leads to worse cooling efficiency
At a glance your issue looks like overheating issue. When CPU temperature exceeds some limit, it enable protection which stops clocking internal circuits to cool down the chip die. As result, the speed of CPU slows down. This state is known as "throtling".
Try to measure temperature of your CPU and GPU heatsinks when you catch lags. If its high, then this is the reason for lagging. Just improve your cooling system to solve this.
Do you have a solid earth/ground connection?
My pc+monitor don't like being un-grounded in a high humidity environment as the screen would glitch to black or won't turn on at all because of a corrupt hdmi signal.
Any equipment with a metal chassis should never be connected to a un-earthed outlet, but because of a house renovation I had to move the pc a few times, including to a old (soon to replaced) socket without earth.
After I realized that it's not about PC components, internet connection and settings, I started to look for the cause in the electricity provided to my building.
I tried to make a choke with multiple ferrite cores of material 31 separated for live and neutral. At the beginning I could feel the difference somehow but the issue came back.
After I realized that it's not about PC components, internet connection and settings, I started to look for the cause in the electricity provided to my building.Mains electricity has no way to influence computer/monitor performance in any way. Everything is powered by switch-mode PSU, where input voltage and frequency has no impact on output voltage which powers the electronics.QuoteI tried to make a choke with multiple ferrite cores of material 31 separated for live and neutral.

They feel they somehow improve audio quality, yet there is no actual difference. Brain works in a way that a high price gimmick can fool perception, even though there is no actual difference.
The issue most likely is either problem with your perception due to some internal reason in your body. Or some external influence like flickering light already mentioned.
Why are you so sure, that any kind of sine wave distortions can be easily filtered by PSU?
Like I mentioned I experience huge desynchronization with any game server, I would say it's like playing with ping 300-400 ms however it shows 30 ms.
Propably my PC is not able to process the informations fast enough due to error correction code due to distorted current causing bit errors.
Why are you so sure, that any kind of sine wave distortions can be easily filtered by PSU?The power supply converts to DC, mainly +5V and +12V, and the motherboard DC-DC converters down to +3.3V, and whatever +1.1V/+1.8V/etc voltages the RAM and CPU want –– they're usually programmable.
Distortions don't degrade performance. If the distortions are large enough to affect the PSU output, your computer would be unstable and crash ("bluescreen", or whatever it is called nowadays).Like I mentioned I experience huge desynchronization with any game server, I would say it's like playing with ping 300-400 ms however it shows 30 ms.That means your network connection is wonky. Can you see the issues when playing offline, without using any network connection at all?Propably my PC is not able to process the informations fast enough due to error correction code due to distorted current causing bit errors.That is not possible. The hardware does not work that way.
Again, if there are problems that get through your power supply, they will cause your computer to crash. Current x86-64 hardware (running Intel or AMD processors) does not have the facility to even slow down in case there is a power supply issues; it either works, or doesn't and crashes (locks up, most often).
That may sound like a madness
Take the PC to one of your friends with known-good network, humidity and electricity. See if it performs there.That may sound like a madnessNo disagreement

You say that your PC doesn't work as it should but your measure of its performance is purely subjective?
There is literally zero point even considering chances things like power line quality until you have an objective measure of your PC performance. Perhaps run a benchmark like 3Dmark when you perceive a period where performance is poor and run it again when you perceive the performance as better to see if there is an actual difference in performance or if you're just imagining it.
Also if you're playing games online the performance of your internet is going weigh in heavily into the smoothness of gameplay. It is quite plausible that weather affects the performance of internet hardware, especially internet connections that use long copper phone lines (ADSL/xDSL), or wireless. Perhaps also, certain weather conditions are more conducive to people playing online games or browsing the internet therefore internet performance suffers during those weather conditions. If it's raining, people are probably more likely to be inside using the internet compared to a nice sunny day for example.
https://www.bbc.com/news/uk-wales-54239180I wonder if it's the owner of the TV set who should have been embarrassed, or the ISP, or most likely both
But anyway, leaving aside the possibility that high end gaming is the new high end audio , network glitches (particularly if nothing bad ever happens in single player games), software problems or aggressive power saving are definitely things that should be considered before humidity, and frankly you would be better off asking on some computer/games/etc forum.
As for mains distortion, forget it. There are three levels of regulation along the way: active PFC, down to 12V, down to ~1V near the CPU/GPU. The sine waveform of mains voltage is actually more of a problem than any distortion.

It does work like that according to -> https://passat.crhc.illinois.edu/hpca_15_cam.pdf + https://scholar.google.pl/scholar?hl=pl&as_sdt=0%2C5&as_vis=1&q=error+correction+code+latency&btnG=
Modern PCs don't crash because of error correction systems, bsods are not that common nowdays.
My internet connection cannot be wonky, because I know many decent players from my city using same provider and they don't experience any issues at all and I saw it personally.
however inputs are as slow as online.
Yes, unfortunately it's purely subjective but I trust for my senses and perception. I don't have access to professional measuring equipment, even oscope. Like I wrote in first post I wouldn't have realized the problem is happening if I hadn't experienced perfect gameplay in gaming cafe. It is pointless to do any tests with benchmarks because the problem are slowed down inputs (click -> processing -> appearance on the screen) and degraded monitor refresh rate, not the performance counted with scores. My current internet connection is FTTB so interference through the fiber is excluded but still ISP's routers may be affected.
fresh format gives a relief for one day and the same claims a lot of other players I meet.
I totally believe you are sensing something real and not going crazy.
I would try to borrow a laptop or another PC (even if not as high performance) and see if they behave more smoothly for you, just to convince yourself you're not crazy (I don't think you are... you just need the PC to flow smoothly!).

Which would point to software, not hardware being the real problem. Consider the opposite situation. Let's say your hardware really was faulty in same way, and messing up your gaming experience. A fresh format, shouldn't make a blind bit of difference, if it does, it tends to point to software (drivers, windows, etc), being the real problem.
EDIT: There are more complicated scenarios, whereby faulty hardware, can eventually cause the software to give up and go into some kind of less functional operation (and lots of other variations). Some of these things can be checked for, by looking in the right places in windows error log things. Which can tell you what has been reported. I'm not a big fan of windows, so maybe google it, or get help from someone who knows how to access these logs. Also, detailed performance analysis tools might help (benchmarks, memory/disk(SSD) transfer speeds, other tests).

What you're trying to do is akin to working out why the engine in your car isn't running right by performing metallurgy on the engine block.
Years ago as a teenager I was a 'gamer' and troubleshooted problems like this without any knowledge of electrical engineering. The first question I'd ask is, do you experience the poor performance when playing games offline? If yes, then you can tentatively rule out the internet as a source of problems. Next things to try:
-Try a different mouse and keyboard
-Make sure you have the correct drivers installed, especially for your mouse and for your graphics card. Also try an older version of graphics card driver - the latest driver may have a bug.
-Turn down the graphics settings in your game. Try VSYNC on and off if your game has the option.
-Make sure your CPU isn't throttling because it's getting too hot
I totally believe you are sensing something real and not going crazy. Some people just have highly tuned sensory systems that get annoyed by things that most other people are able to ignore or don't notice. For example, I remember once deploying new software on a financial trader's workstation. He called and complained a few days later, "the screens are flickering". He had 8 screens on this PC, all bombarding him with financial information. I sat next to him for hours, trying to see what he was talking about. After a couple of hours of intense concentration, I noticed the slightest, tiniest little stutter in the "flow" of information, as if the music stopped on all 8 screens for a brief few milliseconds before continuing as if nothing had happened... I found it almost imperceptible, but I did notice it. He immediately screamed, "THERE!! DID YOU SEE THAT??" - it had hit him like being slapped in the face. Here, the problem was caused by the new software somehow blocking the flow of video for a few milliseconds at a time. I uninstalled the software, and the PC was smooth for him again.
Based on this experience, it seems to me that it is most likely there is a problem with some software running on the PC that is introducing tiny stutters in the smooth flow of video that you notice (maybe subconsciously). You can absolutely get small stutters in the flow of video (gaming) due to things going on in the operating system, interactions between drivers and hardware, etc. - and it can be very difficult to pinpoint.

I don't know what's the relevance of "Windows kernel timer" latency, but 23ms is an eternity by computer standards
And whatever it is, the "kernel" part suggests something to do with O/S and drivers.
(If the whole result isn't a red herring.)
