Tbh i think that all these theories about electricity do not make any sense imo ofc, like there hasn't been a single proper proof of that and yes, I did testing in offline mode and the gameplay was perfect.
Engineers at NVIDIA / ASUS / etc disagrees with you. It's part of university training for electronics circuit design.
Scientific paper proofs:

Plus dozens of links I've made in other threads (including to NVIDIA)
These are stuff you don't read on AnandTech and TomsHardware because EMI problems are SO HARD to troubleshoot, that almost no end users can do it.
Most of the time, it's the companies responsibilities to make sure computer power supplies don't fail with imperfect mains electricity. All the big companies have to add all the proper quality power supplies.
Yesterday's computers did not have error correction so they simply crashed if interference came to it. Today's computer usually just lags when inteference occurs -- whether on a network wire (DSL lag) or on a USB wire (mouse lag from interference injected into mouse cable) or on a SATA wire (disk lag from repeat-transmission of corrupt blocks) or circuit trace on PCI Express bus (lag from having to do error correction retransmit).
But unfortunately with the prevalence of cheap chinese power supplies, crappy motherboards, bad electricity companies with flickery electricity, etc -- they can conspire to create problems. So, we cannot arbitrarily hand-wave electricity. Some people are unlucky to live in locations with bad electricity (funny AC waveforms and overlapping harmonics that shows up on oscilloscope etc).
It's at the threshold of "Does not show up in our beta testing, but shows up with 100 or 1000 legitimate electricity related cases out of 10 million users" -- which is why it is so hard to troubleshoot.
All the "electricity stuff is fake" nor "240Hz is fake" does not belong on Blur Busters, so can that shit please.
We push the edges of science around here. Thanks.
Lag from bad electricity power is usually a domino effect: bad power (flickery/noisy/interference) -> error correction events occur inside a computer -> latency from internal retransmissions -> lag. Just like external latency increases (interference in a bad network/DSL wire creating retransmits), there can also be internal latency increases that were a result of a domino effect from bad electricity.
The problem is almost no average joe user can troubleshoot this. It requires a university degree to troubleshoot -- and the manufacturers have to build good power supplies, VRMs, capacitors, switching voltage regulators of all kinds, buck-boost circuits, etc. But sometimes the input electricity is so terrible, that the best power supply electronics fail to filter it all out successfully away from the circuits.
Even as some people is too eager/insistent (tinfoilhattery conspiracy stuff almost to the point of reprimand by me), I am still a defender of niche cases that are definitively confirmed to happen, with academic proofs. We stick to science and evidence around here. But sometimes the evidence are in advanced paper sites, not at TomsHardware or LinusTechTips. This is metaphorically like using social media for medical facts. If you open scientific eyes, you agree with my electricity problem assertations -- even if it's a small factor. Maybe some of you did not graduate from university electronics like NVIDIA engineers, but if you did, then you already know the EMI stuff.
Changing ISPs solve the problem more frequently than attempting to troubleshoot electricity.
It's crapshoot, we often see a situations such as:
Persons #1-10 -- tries to switch ISPs. Fails in reducing lag
Persons #11-20 -- tries to switch ISPs. Succeeds in reducing lag
Persons #21-29 -- tries to fix electricity problems. Fails in reducing lag
Persons #30 -- (one person) tries to fix electricity problems. Succeeds in reducing lag.
Etc.
There are millions of causes of lag -- e.g. lags of a specific game, lags of specific computer peripherals, lags of 1000 different ISPs worldwide, lags of different power quality in different premises, etc, etc, etc. While bad-electricity-derived lags (error correction cascades) is proven to exist, it's a VERY small percentage of latency problems worldwide. My country has relatively good electricity, and not everyone lives in the same (country /state / city / block) as you do, as lots of lag problems are often area-localized.
Just because one solved your problem or did not solve your problem, does not mean the advice is appliable to the other person because of a different location. Not everyone lives in the same house as you do. Correlation is not causation!
Readers should not thump their solution on others as an absolute mantra. It may and may not work, and a different solution may work for them, even if symptoms are near-identical. Respect.
Be nice (That's the Blur Busters Forum Rule Prime Directive).
However, I agree with you, the problems in this thread is *probably* network rather than electricity. But we are Blur Busters here, we incubate crazy edge cases of temporal issues in gaming (display Hz, more frame rate, VRR, MPRT, GtG, latency, whatever). We are the people who unceremoniously shoot down doubters in the temporal domain, whether rebutting the 240Hz disbelievers, or "humans can't tell 1ms" luddites. While some users enthusaically exaggerate/overstate the size of the electricity problem, the bottom line is that Blur Busters spend hours writing stuff to stamp out this stuff. You've been warned about handwaveoffism around here. Winky wink
