[Power/EMI] I discover why sometime PC become fast and low input lag and otherwise feel high input lag

[Nawafwabs]

I did this test 2 days and i check it and it confirmed that the emi is the main issue

if you think power condition will fix it 100% this is wrong

You need to fix the hole house or you face this delay all your life or maybe you move to other house and do emi test over 24 hours to make sure not effect by other things

I am Spanish-speaking and sometimes I don't understand very well when google translates for me. I have the same symptoms that almost everyone with this problem with the difference that I take my PC to other houses and it works just as bad, I sold my PC and bought a new one thinking it could be a hardware problem but the problem came back, I changed components 1 by 1 and the symptoms did not go away. Now my theory is that my house does some damage that wherever I take it will have the problem. Now I wanted to ask you what you mean by fixing the problem or you will always live with it. I know it is a problem of electromagnetic interference and now I will install an earth bar to see if this solves my problem or what you recommend doing.

Installing earth with 0 ohm will help

And reduce high emi will help you also

Thank you very much for the answer, another question my house is a bit old from the year 1985 and I think that the circuit wiring is not shielded to reduce interference, if I do this installation of the grounding do you think it helps something or is there any method To reduce the interference, I have seen the videos you have sent but they are in English and I understand very little. Thank you

I came across this reading about emf/emi stuff:

Using an AM Radio to Detect EMI
https://www.youtube.com/watch?v=lXPJvSU8MwI

My benq monitor has noisy power circuitry right above my mousepad and makes the most disturbing noises compared to rest of the system. Using the metal side panel of my case seems to quiet it down some when I try to shield the mouse area, but need to test more to see if it affects mouse movement.

Confirming that upgrading earth/grounding helped immensely in input lag/mouse movement consistency for me.

DISCLAIMER: If your not sure what you are doing, please find a certified professional to help, especially in a country with stricter laws/liability concerns.

A while ago I measured neutral to ground voltage on home circuit with basic multimeter(no millivolts ability), giving a reading of 0 volts, so I assumed the grounding was good enough. However, watching the grounding video Nawafwabs shared, it is possible to make less resistance/impedance grounding by wiring together multiple rods which is not that difficult to implement. Having better grounding will in theory help equipment have an easier time getting rid of emi/rfi/emf noise.

I purchased three copper plated steel grounding rods(1 meter length) for under $3USD a piece. Only computer system is wired to this ground and right away noticed the difference when moving the mouse in-game. Highly recommend trying out to anyone who doesn't think this too impractical. Going to add a 1.8 meter rod next.

How do you connect the grounding to your computer? Do you just take the wire running from the socket to the computer and connect up to the gounded rod(s) whilst it's plugged in the computer?

How do you connect the grounding to your computer? Do you just take the wire running from the socket to the computer and connect up to the grounded rod(s) whilst it's plugged in the computer?

Make an outlet/socket extension that uses the rods' grounding:

EDIT: I found that NOT connecting neutral and ground together works better.

And put in a box:

The shop with the rods might also carry these.

Again, please be careful, double check things and make sure all connections are clean and tight.
By adding a second ground, there is something called a ground differential that is possible and can be dangerous if you have electrical equipment next to each other and touch or connect both when they are using different grounds. As long as its just your computer at the desk you should be fine.

I added two more 1.8m(6ft) ground rods and felt more improvement after adding the first rod, but no more after adding the second rod.

If I would do over again, I would use four 1.8m(6ft) rods in total. Its been raining often here so the ground is soft, but if you have trouble driving in the longer rod, you can keeping pouring water and the rod will eventually go down.

There are some rules of thumb to follow to lower the resistance as much as possible:

The distance between each rod should be about twice(2x) the length of the rod, so 2m long rod should be 4m distance apart.

The resistance is lower in high moisture soil, so if you have spots where water falls off your roof or where your gutter exits, it would be ideal to place the rods near there.

Loose soil is worse than tight, so if the rod goes in too easily try a different spot that is harder, you should plan the layout well, it should be almost impossible to pull the rod back out after driven down.

How viable would it be to get rid of the houses' ground and just use your own, with the rods?

Hey did this fix it for you? I would try this also next. I have this problem since 2 months but dont know what exactly happened that i got it too. But i tryed my PC at a friends house the Mouse feeling is a bit better but the Input lagg much much better. Came back with my Pc to my House and it worked for about 20-30mins better and i feeled how its getting worse again. Is it maybe the same problem with grounding emi rfi?

In the diagram, the X on house ground, means do NOT connect the house ground to the new outlet. Anything that connects to your computer and has a ground, like the monitor should also use the new outlet which only uses ground from the rods. The problem we are creating is making another neutral to ground bond, which is described here (4. Multiple neutral to ground bonds):https://electrical-engineering-portal.c ... ound-bonds
I think as long as your computer and all related devices are on the same new outlet extension, we have a new "sub-system" and should be safe and viable. Please read the rest of the points too, in particular if you have a lot of lightning strikes near your house, the points lower down talk about having multiple rods. I am not at all qualified to advise on these matters, if in doubt please consult an expert to determine what is safe.

When you say input lag much better, is that offline and not something that having a better network/internet connection is fixing? If it is offline that you can feel a difference, than there is a chance this could help.

Re-reading the different topics about emi/power problems here and on ocn, I think there is a wide spectrum of how severe each person's problem is. There can be electrical problems of all shapes and sizes and many are beyond our ability to correct.

In my case it is not that severe, everything is running smoothly, no stutters or lag, hitreg is fine, its just that most of the time, mouse movement is not as controllable as it sometimes appears to be after playing with ferrites or changing bios settings or moving fan/power wires around. Before noticing those things, I thought that the mouse inconsistency was due to humidity levels and how much friction the mousepad had.

I switched back and forth between the new and original house grounding to test a bit. With the house ground, the mouse still feels floaty/slippery versus the new ground which makes it easier to track and control and more importantly is consistent. However, from the desktop or for somebody who doesn't play FPS games it would be hard to tell the difference. LatencyMon and MouseTester show no differences either. If you or someone you know is comfortable with home electrical wiring, I think its worth the effort to try it out.

I guess the biggest problem at my pc is also that the mouse feels floaty. I got 3 new pcs and they all worked fine for about 20-30-50Mins and after that always this weird mous feeling. Fees like the mouse is on ice or something like that. Was it nearly the same for you? I think i noticed it everywhere also in bios very laggy or on desktop also weird. And glad to see that people like you could fix it my problem started since i installed a metall house next to mine and we also put electricity in it. but i dont really know what we damaged there. Under this house there are also internet cables and also electric. I hope i can fix it too
