My input lag finally makes sense to me. (Please Read)

[Kanipshun]

After 6 or 7 years of dealing with input lag, it finally made some sense to me tonight. I thought for a while that it was a driver issue or some kind of conflict. The problem with that is that it can never be fixed by changing drivers. All of the crazy "fixes" in here work. For me they seem to work once and then never seem to work again. Two days ago I was frustrated with horrible lag and I decided I was going to fix it or quit entirely and I was almost done. I did 2 new fresh windows installs and I added drivers one at a time. It made no sense but I would eventually get the lag back.
I realized, it's not a driver issue nor is it a hardware issue, it's a power issue and I'm going to explain how.
Now, I don't know exactly what is happening inside the pc but I'm starting to understand it.
Between about 3 PM and Midnight, gaming is horrible. Between midnight and 7 AM it is much better and EXACTLY at 8 AM any morning, it is absolutely flawless. I can honestly tell exactly when it is 8 AM by the way my monitor looks. It's clean, has color depth and it looks so much different than it does on those peak gaming hours.
What happens at 8 AM? Power consumption goes through the roof and power companies must push more out. IT'S NOT DIRTY POWER so don't waste money on some triple-quadruple sine wave power cleaner and a new PSU will not help (don't ask me how I know this).
Ever wonder why Quebecer's are so damn good at games? Go look at all the hydro dams they have. I don't think they run into this problem and their "8 AM Gaming" lasts all day.
All of the fixes on here work. They may not work for you but I guarantee every "fixed it" post was someone who fixed it for a small time.
I honestly thought for a long time that maybe there was some kind of conflict between the monitor and the pc which causes the problem. Like maybe it was a grounding issue but I don't think it is. I live in an older home and anytime I turn on any appliance, it dims things elsewhere in the house. I would venture to say that my input lag is worse than 90% of the people here.
There is a solution tho. I can have very good gameplay in those peak hours by trying one of the hundreds of fixes here but I discovered that certain things make a huge difference. The most important thing that helps my AMD mobo is moving my ethernet off of the back panel and using a pcie card. I don't know if it matters but the Realtek card I got seems much better than the Intel one on the mobo. I personally don't think the brand probably matters, just moving it away from the other usbs.
The biggest thing I have found that fixes the issue is simply disconnecting everything from my pc and plugging it back in after a quick blowie. I realized most of the time I have done this, the PC runs perfect afterwards and no, it's not from dust. I keep my PC cleaned often. Another important thing to do is randomly taking things out of the usb ports. I pulled my keyboard out at random intervals and plugged it back in and it seemed to keep improving things. If you are getting lag then you need to move certain things away from each other or possibly locate some closer together. I can tell you with certainty that any usb audio should be as far away from your ethernet port as possible which is another reason to buy a cheap Realtek pcie.
The one thing that just didn't make sense to me forever is something I now see. YOUR MONITOR, whether its on a dp cable or hdmi is behaving exactly the same way as the USB peripherals and is also fighting for power. I can introduce a lot of input lag simply by turning up my brightness and (especially) contrast. I had also noticed that playing games, night maps makes my computer run perfect and there's certain maps that I get good fps but tons of input lag. It's usually maps with a lot of different contrasts. If you are suddenly going to be using more power somewhere, whether its on a keyboard, on your monitor, on your mouse, those rgb lights it causes problems.
It really is worse a little while after you start gaming. It doesn't matter if you leave your PC on all the time because it seems like it enters some kind of stasis. The next time you come home from work and ready to play a game, I'd like you to try something. Just turn your PC on as you normally do and start playing. Once the lag sets in, usually takes about 10-15 minutes for me, turn your PC off and unplug everything. Take a couple minutes to clean it out and then plug the power in, connect the monitor and plug in your KB. Turn the computer on and start plugging everything else in. Take some time and let all of the drivers adjust to where you plugged things in. DON'T plug things in the same place you had them before. It's not important to change everything, just some or most of them. Also, don't worry about what kind of USB it is. I found it's best to fill all of the USB 2.0 ports first. Now slowly start loading programs you use and then your game etc. You are going to also pick something accessible to randomly pop out of the usb at small intervals. Maybe unplug your KB every 5 minutes and repeat a couple times. Let me know if this works for anyone, it has done wonders for me.
And yes, you can have perfect gameplay when you normally cannot.

So you went from a correct culprit - overloaded electrical grid during the daytime - to some "move cables, change ports, blow dust from your PC, re-plug peripherals"? Placebo fixing...it cannot be "better" or "worse" - you either have a problem, or you don't. And if the problem is power as you correctly assumed, then nothing you mention will really help.

It's output lag, not "input" lag. Your ports doesn't matter, everything you click or type is correctly inserted into the mobo, the CPU correctly processes it (and this is why none of the software tests will ever pick up anything - latencymon is perfectly fine, FPS is high, everything is fine), but when the information is trying to reach your monitor, it gets corrupted. It's a de-sync between the MOBO and output monitor, NOT between mouse/keyboard/whatever inputs and MOBO.

Resolving such issues is beyond the expertise of most people.

Please give proper arguments for overloaded grid or don't spread misinformation.
We have seen every variation of such explanations, no one is interested in crap anymore, just hard data.

[MK92]

I have hard data. Harmonics / interharmonics levels during the daytime are much higher than in the late evening, it was measured for 3 consecutive days by professionals. And this correlates directly with PC performance - from 12 pm to 9 pm it is basically impossible to use PC without going crazy (NOT just gaming, but everything in desktop), but as the grid clears up late at night, it gets so much better it feels like you suddenly have a completely different PC and monitor.

If people changed every single component multiple times, did 1000 software and bios tweaks, tried computers at other locations where it works fine, it can be only one single thing - electrical grid. If you move to another location with the same monitor, PC and software settings, then the only thing that changes is electrical grid...so, what is the cause of our problems? Our bodies? No, its the grid.

Dear author, the Russlan community discovered this method a long time ago, but it involved unloading the processor and setting threads and cores. With each connected USB device, the threads change, and especially the core load, and vice versa when you disconnect. This is a very delicate topic. There is a lot to write about this, but this method does not work for long. You are not going to pull out the USB keyboard every 15 minutes, disconnect the mouse, and then blow dust out of the PC, are you? I recently lost my level 8 Faceit rating and almost reached level 10. I know a little and a lot about what I'm writing here, but apparently the author went too far in trying to convince people to just do it without supporting it with reasonable results and tests. Every change in Windows, such as disabling the firewall or power supply, or disabling “unnecessary services,” or changing the registry, changing the screen resolution, and many other things can improve your gaming experience, but as soon as you restart your PC or after a short period of time, everything will get worse. The same applies to disabling USB components. The streams are redistributed to the cores, which makes it a little easier to breathe, but unfortunately, this does not solve the problem. Just think about how it does not affect the registration of hits or the network as a whole. All the times mentioned by the author can change, from 1 a.m. to 3 a.m., and then everything will be terrible to play, and after 5 minutes of playing, you will have perfect gameplay again. Our problem is still unclear! It's either electricity, which is very difficult to prove, but everyone refers to the fact that it's bad during the day and good at night, but what about provider overload? Packet loss, as well as UDP, which fires packets like a machine gun, and because of this, there is packet loss? No, it's not because of that? What if I tell you that because of the internet connection or a lousy server, for example, Faceit will have less fps than it used to? And therefore, a bad gaming experience! The author has never noticed in the gameplay, for example, in Faceit, that on each server there is a slight difference, but there are no changes, no UPS stabilizers or any other nonsense will help you with the internet! Remember one truth: Windows and all peripherals work out of the box! Professional gamers don't configure anything! They play as is. If you go to YouTube, you'll be surprised to hear them say that they didn't disable or change anything and that they have the default Windows BIOS!
As I wrote above, it has not been proven that the problem is with the electricity or the internet. Perhaps it is a combination of small problems that affect our gaming process, resulting in one big problem that has been discussed for almost 15 years! But these are just my personal assumptions! I have tested many schemes for suppressing high-frequency grounding, etc. I know many players who have already reached level 10 but cannot jump the 2300ello threshold. They have spent a lot of money on solutions to their problems related to “electricity,” but it did not help them! Many thanks to the author for writing this, but there are no tests, no information on how long it has been playing like this, and the probability that the game will deteriorate in a week is about 75%. Guys, when you post something, prepare tests right away, how long the minimum of a month of good gameplay lasts, and at least screenshots of one game or another where you win or at least maintain a good KD or significantly outperform your opponent. And most importantly, proof that it really works and not just that I did it and got lucky when you were at your best and everything was ready. Not everyone is willing to check and do things without proof and explanations! I apologize for the translator if anything sounded rude!

And do you know why no one has solved this electricity-related problem yet? Because it cannot be solved by us, ordinary people, unless you are going to break into a transfomer substation and upgrade / reconfigure it by yourself.

What would solve this problem:
-Transfomer substation, which is directly responsible for providing electricity to your home, needs to be inspected for any floaty neutrals / bad grounding / leaking current
-If the grounding and neutrals are okay, then they would need to increase voltage and wattage at the substation.
-If this won't work, they would need to use some active/passive filters, and basically re-configure entire substation.
-If still not better, they would need to identify which consumers are causing problems, because there must be some faulty device that is interrupting the entire grid - most likely solar panel, but could also be old washing machine, fridge, water heater (boiler) etc.
-They would need to re-route problematic consumers to other grids, to free load on your grid

See why this cannot be solved by none of us? Even for power company, this could be expensive and time consuming, and they won't fix it just because one guy has PC problems. I talked to professionals about that, they explained exactly how electricity is distributed, and they told me what I said above, you cannot fix this by yourself.

So why do issues remain on a UPS while fully disconnected from the mains/grid?

[JustNumber]

Try also test between 11:00-12:00 or 12:00-13:00. In my case also all problems gone in this time.

because that not electricity
