Funny you mentioned power outage. Because the other thing that changes when lots of people are home is voltage drops (more likely in an apartment building). Also more likely in cold weather.
Does it happen with laptop disconnected from the grid? Or desktop connected to uninterruptible power supply and disconnected from the grid?
Well, here comes some more info xd sorry in advance for the long post ! lol
I don't have a laptop only desktop pc, and don't have an UPS either unfortunately, I could test that easily but I don't really need to, because I already did what I could to exclude issue being in the hardware/pc/monitor itself on my side, i'm sure that laptop on battery would feel great, idk about UPS if it would fix the problem,
but yeah all the symptoms and all testing I already done the past 2 years (started with replacing every single hardware component and cable including monitor etc, then have taken the new hardware to other locations/friends to test, there it works flawless and normal as it should with a 100% constant mouse feeling that is identical no matter what time of day it is etc, only talking about offline gaming/desktop mouse feeling now, when it feels bad on desktop it will for sure feel bad in online game too anyway so..)
what you said about voltage dropping and cold weather, is possible, but even on the summer the phenomenon occurs, :S could still perhaps be voltage-drop related or at least maybe it is part of the problem, in combination with some form of RFI/EMI/THD problems coming either from neighbours or power provider equipment in my building or similar, I never measured voltage or talked to electricians about it, I really should have but eh, i'm far less competitive gamer these days and the time I have free to spend to play some games is usually around/after midnight anyway, which in most days of the week will feel acceptable / great for me,
about cold weather, right now for example its -11 celsius outside and 73% humidity and the time is 06:09 CET here, mouse feels perfect at desktop so I know it will feel perfect in games too in my case, but this doesnt really mean anything to me because I can't control these factors anyway like weather/humidity/overall power usage in my area..
also will be moving from here this year and I mentioned earlier also I tested my hardware at friends places on other locations, feels flawless there 24/7 and i'm just talking about offline here not even online gaming, so at this point i'm just accepting the problem until I move the hell out of here xd
also from what I understand a good powersupply can handle voltage drops and even if it did not, the symptoms should not be random input delay I think? more like crashes or freezes ?
I really think its like what the Chief (admin of this site) said in many of the threads about this issue, that it likely is some sort of interference on the power which leads to the numerous error-correcting systems in modern PCs to act strange and delayed, nanoseconds turn into milliseconds of lag etc from the error corrections, I just wonder if this could be logged somehow or analyzed/measured...or if its on such a low hardware level that the operating system is not even aware of whats going on and its just on the motherboard chipsets perhaps? (kind of talking out of my ass here and just speculating lol)
but at least Chief says its not out of the possible reality at all, and has confirmed it himself in some scenarios from what I understand,

IMPORTANT NOTE TO ENGINEERS / Ph.D's
While most of the time, this is a wild goose to red herrings, and EMI is definitely not the cause of most computer lag problems -- there are actual cases of EMI creating human-perceptible latencies because of the large amounts of error-detect-and-retransmit mechanisms inside NEWER computers. Even a modern PCI Express bus and a DisplayPort cable are both packet-data systems nowadays with error-detect and retransmit = LAG instead of CRASH! Death by a million nanoseconds.

its fascinating phenomenon to me anyway, I just hope it will not become a more and more common problem for people in future, and for example when I move out of here, the person that moves in, if that person is a gamer its gonna suck for him/her bigtime, lol... its fucked up !
remember reading here also some user had frametime spikes occuring in exact regular intervals and had tried everything replaced everything etc, and in the end it was his solar panels that was sending some info or status update over his powerlines in the home and everytime they did that, he got massive frametime spikes / freezes in games
