For the first time in a very long time, the input lag problem is completely gone.

I also believe that the issue is electrical in nature. Otherwise, it simply doesn't make sense.

I live in a newly built apartment building, and I assume it uses either a TN-S or TN-C-S grounding system.

Recently, I hired an electrician and asked him to check the grounding and power quality in my apartment. According to the measurements, the grounding was excellent and the power quality was also good.

When you hired an electrician, were you told that there were problems with the power quality, grounding resistance, or any other electrical parameters? Or were you told that everything was within normal specifications and there were no issues?

Until you guys can actually measure and capture the "PC working bad" because of "dirty" electricity to me it's all schizo posting and placebo. There is literally zero videos/benchmark that show the difference between how pc works on "clean" vs "dirty" electricity

Lol, the UI animations in windows, browser, anywhere loading slowly and choppy like the refresh rate on the desktop is actually below 50, websites loading slower (NOT an internet speed issue, but processing of the CPU), mouse leaving trails behind and being delayed (moving mouse left and right at moderate speed provides like 5 cursors at the same time on the screen, because refreshing and frametime pacing is so low). And among many examples, if you put 3 icons on the desktop, one above each other, and you try to move cursor above all of them up and down fastly, the one in the middle won't even be "registered" - i.e. it won't be highlighted like it should, it simply skip this input and goes to the next icon.

Not to mention clearly degraded visuals like blury text, washed colours, brigthness of the monitor clearly being lower than it should be and is "wobbling" and "breathing" etc., you don't need to measure something that can be felt by using the PC for literally 10 seconds that everything is off, from refresh rate, output delays and desync between picture, sound and inputs, frametime pacing is broken, typing is dealyed, mouse is delayed, everything is delayed because of error-correcting protocol that triggers when there are power issues.

And I have a measures - the neutral drift between L and N+E was 6V and even higher right after I turned off appliances, while now when the PC works perfectly it's below 2V.

This is what actual power issues does to a PC, while people which are "behind the server", "hitbox is not correct", "enemies see me first" and stuff like that, yeah they are probably schizos, since this is done server-side and cannot be caused by electricity.

All of these issues listed and yet nobody has ever caught that on camera? Why? because there is no such thing, electricity has no effect on your monitor quality/refresh rate or the speed of your pc, its impossible. Unless you can prove me wrong

Sure, electricity is just an ON/OFF binary state, it either work and power up the PC, or it doesn't...my ass...if you have no idea how a broken neutral reference, neutral potential, polarity problems, high impedance, voltage sags and fluctuations, neutral drift, ground loops, harmonics, or just simple stuff like corroded and loose connectors etc. etc. could interact with sophisticated and sensitive devices like modern PCs, then you better don't say anything...this is like saying that tyres on a car have no impact on car's performance or some crap like that.

Power issues are causing 90% of problems for people in this forum, its just that someone has minor electrical issues (= minor symptoms), and some of us had huge faults in installation (= major symptoms, and almost non-usable PC). If the PSU's active PFC cannot regulate power correctly anymore because the electricity is bad, then 3.3V, 5v and 12V internal rails collapse, ripple increases, transient response became shit, and you have those symptoms.

Finally somebody who has a "real" understanding of what is causing all this weird symptoms.

It was decided yesterday at the owners' meeting that all electricity meters in the basement must be enclosed.

On this occasion, the entire electrical installation is also supposed to be modernized.

Currently, we have a TNC-C system which is now almost 60 years old.
And it’s anything but suitable for modern electronics, especially high-performance PCs.

I’m 99% sure this problem will be solved once the construction work is finished.

For anyone interested in what a TNC-C system is, you can google it. ...

I live in an old apartment with TN-C system, the bars are located in the hallway, not in apartment itself.

In my case, it was like this:

During day:
PC worked bad whole the time, but not extremely bad ---> if I turned on oven, induction hob or clothing iron, the PC became great ----> when I turned OFF those devices, the PC became even worse than at the beginning, it was literally not usable - it needed about 1 hour to stabilize and became just "bad" again, not extremely bad.

During night:
After midnight, it always worked perfectly fine for some reason.

So it was probably two different issues - the first issue was a 55-year-old wiring in my apartment that was probably corroded and broken already, and this was fixed by bypassing the wall wiring by installing a fresh dedicated current - this fixed PC instability during the day and oven / induction effect; I also had PC socket on the same circuit as those appliances. It was 99,99% neutral drift and neutral impedance issues, and then voltage sags.

While the second issue was apparentlly dirty electricity coming in from neighbours through shared neutrals, and this is why it worked fine at night. Looks like replacing the connectors at neutral bar fixed this, or maybe the entire fix was just a dedicated circuit, OR it was just a faulty neutral bar and I wouldn't even need a dedicated circuit, who knows.

Hey,

really intersting answer.
I think i have the same situation, can we maybe connect on discord or something ?

I would really apreciate it

[Flexoh17]

To non believers, I have the same issues as OP, the same symptoms and causes of them(i think). The oven or an air fryer, when they're on the peripheral input and image output changes. At my situation even cables like monitor power cable and an ethernet cable that comes from the hallway of my flat, when touching makes these symptoms. In a couple of weeks I will try to get in touch with an electrician to see what kind of fixing i need is it new wiring, grounding, missing neutral. But this is real, probably most of forum users are from some country which has followed the standarts of installing eletricity in homes and flates for decades, but in my country we have a lot of post soviet buildings where the only standart for installing eletricity was to have two wires. I hope I will not forget and get back to you after I get things done with the eletrician.

Classic TN-C behaviour in old apartments with oven, stove, induction hob, ironing, hairdryer etc. causing voltage dips and neutral drift/neutral impedance, you need a new dedicated current with fresh wires and TN-C-S topology for that current, it should not be shared with anything else in the apartment.

Hey MK92,

can we please get in touch regarding to this topic ?
Im planning to do this too, but i still have some questions.

Just add me on discord: akaza3

[Yazeedtt]

Neutral impedance and voltage drift changes constanlty depending on load, and admins still call this "niche issues" lmao, 95% of people here have electrical problems and nothing else. I fixed it by getting a fresh dedicated circuit and fixing main neutral bar.

Dm bro

How can I get in touch with you? Unfortunately, I’m unable to send private messages because I only registered recently. I’d like to ask you a couple of questions about electrical wiring and isolation transformers.
