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.

Who are the rich people who solved this problem? You got any evidence? Or you are just making stuff up. Also show me the proof of your PC working better at other locations. Several hours is not enough to confirm. I can buy a new PC and it will work great for a week or two and it will eventually go back to c*ap.

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.

Funny thing is that firefox font is just bad and jaggy compared to any chromium browser

During the day or early evening if I turn on the PC and start playing after 20-30 minutes of playing the mouse becomes heavy, the game gets out of sync, the hitreg gets worse, the monitor gets slow, the sound gets worse, everything degrades it is something that accumulates until it becomes unplayable, in the early morning between 00 and 5am approximately I play for hours and everything feels stable.

At 5-5:30am it's like a switch is flipped and everything gets worse quickly.

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?

Hello, I spoke with my electric company and they told me that 2 years ago when my problem started they made several changes to the electrical system and one of them was to ground the transformer and unify the entire electrical system in the area in a single point, here in my house the electricity was cut off quite often, after that it did not happen anymore, but the problem with that is that if there is any interference at any point in the electrical network now it reaches my house... In conclusion, my solution is to isolate myself from the electrical network with batteries or some type of generator, there is no other solution on my part... I share my experience in case anyone is interested.

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.
