All your "floaty mouses", degraded display quality, 240hz feeling like 60hz etc. is 101% caused by harmonic distortion.

Separate area for niche lag issues including unexpected causes and/or electromagnetic interference (ECC = retransmits = lag). Interference (EMI, EMF) of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction latencies like a bad modem connection. Troubleshooting may require university degree. Your lag issue is likely not EMI. Please read this before entering sub-forum.

@MK92 Same perfect situation where i live (Milan Italy - midnight till 5.am every hs get register) exactly the same u described... Got a ups and tbh is a little better but far away from a smooth gameplay. i heard isolator transformer galvanic filter a lot of harmonics? is this true? should we go for a try?

I live in a town of 200 homes, it can't be possible that I have harmonics, apart from that my electric company measured the harmonics and didn't find anything out of the ordinary... My PC/Games works perfectly at night but during the day it's unplayable.
Okay, but what problems do you have exactly? If you have ONLY weird mouse movement in games and nothing else, then this is NOT due to harmonics or electricity related at all, it is probably something completely else and is related to the internet network.

If you have harmonics / electrical problems, then it would affect everything, not just aiming in the games. Even when I type here, the inputs are slightly delayed, the screen feels like its 50hz and my eyes hurt, not to mention choppy animations of everything, it feels just like running a grapchics card without any driver, just "raw". Even just closing a tab in Firefox is extremely choppy, like it needs multiple frames to complete the task, but at night its fast and super smooth. And not to mention the display quality - colours are clearly washed out, and some fonts, some specific letters, especially if they are in bold, are either blurry or wrongly rendered, jagged, it's hard to explain, but they are wrong.

I have the exact same problem like you and also don't have issues with harmonics in my apartment. I don't know a single person that traced their source of interference which is why the problem evolved from being- "Dirty Power to "No ground=Problem" to "Ground loop" to "EMF/EMI" to "Harmonics" and finally to "Supraharmonics". Use the search function and see it for yourself. You are about 7 years late to the party. All the users who talked about this quit when they figured out they were mislead and couldn't admit they were wrong. Btw, you still haven't answered- who are the rich people who solved this problem with $6,000 generators?
It was someone on this forum, probably in that thread with 112 pages. Said that the generator fixed the issue, and weeks later it was still working fine, and then disappeared with no further posts.

Are you trying to suggest that there are people which tried multiple PCs, monitors, modems, mouses, at multiple places with confirmed perfect grounding, new installations, working neutral wires, low levels of harmonics (to confirm that, the power company would have to do it for you, unless you have osciloscope) and other kinds of noises, like RFI, EMI etc., and STILL have those problems? Not possible.

The only possible explanation would be that you used some perihpeal that was already exposed to harmonic distortion, and then messed up your new computer when you plugged it in. When you go to the new place where the electricity is fine with no noise, you also need to use a completely new PC and monitor (not a single wire should be re-used, not even fans - nothing), along with new mouse, headphones, keyboard, usb sticks etc., which were not previously exposed to "dirty electricity" at your old place.

Still a better explanation than your "body theory" - so how come that at other places everything workds fine? Is your body emitting something only in your room to mess up with the PC, but at other places its fine? Then simply leave the room and let someone else operate the computer, to see if they would get the same issues as well.

For me, it is clearly harmonics - I have a report from the company, the values are too high during the day time, but after the midnight they decrease heavily to acceptable levels - and this is exaclty when my PC works okay...it cannot be a coincidence.

Now why the double conversion online UPS doesn't filter out harmonics even thought it should, is the other question and mystery.
So it is not "rich people" but a random guy on a forum who left because the problem returned and didn't provide further updates or any proof of before and after.

I'm not suggesting anything- I'm telling you that was my experience. I moved a lot and currently live in a modern apartment with modern infrastructure. It is not possible for you to believe because you most likely never moved or didn't move as much as me but you will find out it is not a solution.

It does not work like that. Peripherials do not get infected or damaged like that. If it did work like that this problem would spread like a wildfire- Even if it did work like that i built my current PC from a scratch and ordered parts from a reputable store.

This problem has remained unresolved for 15+ years since so saying that it is caused by body doesn't sound as crazy when you are like me and you exhausted all other options.

It is a coincidence because harmonics are sadly everywhere now, we are bombarded with that stuff so what you are seeing during the day is normal for most people who live in apartments. If it was an issue you wouldn't see so many pro players come from Russla and Eastern Europe who still live in commie blocks built in 19th century, with horrible outdated infrastructure sharing grid with hundreds of other people.

That's not fully correct. Peripherials DO get "infected" by harmonic distortion, there are published reports from engineers that harmonic distortion indeed cause malfunctions in electrical devices, shorten their lifespan, cause overheating, and even damage it to the point it would be useless - but for this to happen, it would need to be exposed for a longer period of time of course. So if you would plug in a new keyboard into harmonic distortion it won't break after 15 minutes of usage, it would take months of being exposed to harmonics to get "infected".

I'm not following e-sports scene, but I'm pretty sure there was one famous Russlan player who got this problem when moving away from parents apartment into his own apartment - and then had to move again because it was unfixable, so it is not that rare.

By the way, do you have a laptop? Try it with removed battery and plugged directly into a wall socket, and then try to fully charge the battery, pull it out of socket, and run only on battery...harmonics cannot get "stored" into a battery, so if you have any kind of electrical issues it should still run fine on a battery.

You mean stuff like this https://www.seimi-equipements-marine.co ... n/pdt_8408 ? The price is way too high, so probably not worth trying...and stuff like that is used on ships, not for PCs...if double conversion UPS doesn't fix it, then this probably won't either.

It can cause device to malfunction not for a device that is malfunctioning to infect OTHER devices. Big difference...

I heard about him and I don't think he solved his problem, he talked about moving to Moscow but he never updated anyone if he solved his problem as far as I know. I can't find that video anymore it might be deleted but he was talking to a popular Russlan CSGO streamer.

My question for you is; If you think hardware can get infected or damaged, why do most people claim that the problem dissapers during the night (myself included)?? If the PC is damaged it can't repair itself and work great during the night.

I don't know. It could be that the PSUs are getting immediately "destroyed" when exposed to very noisy and low-quality electricity, and then it cannot tolerate it anymore - it would work well only at night, when the grid is cleared with less linear consumers (PCs etc.). Modern PSUs are actually supposed to be very good at noise shielding and "fixing" bad electricity before the current goes to the MOBO, so I don't know anymore.

If someone could get an original, still working PC from the 1990s, it could be easily tested - in the past, the PCs simply turned off when exposed to high harmonics, EMI etc., but modern PCs would try to "correct" this noise - which causes lag.

If the computers had been turned off in the past, why is there no record of it anywhere, not even a video?
