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

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.

- play with mouse 125hz same for keyboard
-disable audio in bios and use seperate audio card
-a very low mouse acc makes the hitreg somehow better cause I believe the input gets calculated more and has a higher priority
-use single core in games
-rawinput off for me it’s better
-late night problem gets less like at 3am
-low FPS and low hz better
-when one core over 50 percent it usually gets worse
-watch if ur cores are like Changeing and not like more static that some cores are near 0 usage always (ofc first cores are higher all time)
-disable as many services as u can
-Limit CPU usage process Lasso etc
-change different drivers to high /real-time every time
So as I understood all these fixed your problem?
Btw, I wouldn't recommend cheap USB audio cards, because DPC latency is super high. PCI is fine I guess..

None of this describe fixed this problem just less noticeable in some cases
for example
-- play with mouse 125hz same for keyboard // kinda true
-rawinput off for me it’s better // also true
-low FPS and low hz better // it is possible
and also 64 tick is for me better then 128 tick also true

Hi guys like I have this issue since 3 yr
I know it exists because on aimbotz CSGo I get Times with deag like kioshima (normal settings no flex)
And when I have this issue I get constant plus 10 s

People call me either bot or cheater
Because they believe it’s an excuse my lag
Idk some magical days once a year it’s off so I did 20-0kd in a wingman and 17-1 18-2 after that
I remember it
I played against a French pro on my lap where this issue comes after some time and I did 17-0 kd and then issue came -we lost I think he even was on stream and said :this guy 🤬
And I honestly asked my mates are those bots ?
At that time I didn’t even know this was a pro

So I believe there’s so much to lag hitreg delay etc
And I’m tied for people calling me bad and saying it’s placebo thats why I had to tell this here not to show off or flex (pls I’m not that guy)

I put more than 4K hrs time in alrdy in trying to fix

Espacially in CSGo I instant know it when I have it like when I shoot chickens they don’t die sometimes I need 3bullets (they are less than 1hp) but I see bulletholes when I watch demo it looks like I didn’t even shoot that direction even when I stood still and shoot slow...
Vents don’t break or like bullets go through or dissapear also it seems like I’m easier to hit because I change wasd slower
Also I die a lot without seeing Sb when he’s peaking (and don’t shit me I’m global ,when ur off lags u can even control each bullet in a spray)

On a certain map (mirage) there a space where u can jump out without breaking vents and every time I got them I don’t make it

But on my lap it’s ok for 5min I play
And when I shutdown disconnect battery and power and press down
So it’s fixed for like 5min

So I believe it’s sth like cmos RAM
Or some transistor is faulty
It could also be that Theres a Spike which kills sth and then u get the problem
Like if cpu spread spectrum ist working anymore or sth like that

Because I tried 4 cpus 4gpus memtest ran etc everything else also different boards etc
240hz Monitor constant over 500fps with an i9
Fabless psu for 250 I also tried
Like I have 5 mice etcetc etc even Keyboard
My 8000hz mouse lags even in 4000hz mode in all games I play

(Idk one night it was like was gone for one day after I connected the second 4pin cpu)
And that night I watched like the usage of my cores and it was like changeing all the Time and they al were more like balanced... at 40-60 percent

EG in warzone I get often lieb 4 cores at 100 percent and the other 4 at like 0-6 percent etc

I tried single ram slot it was better
I tried oc ram even 5ghz
Even once 1.7v nothing changed

Tried like 98percent out of bios (Asus and MSi)did fr33thy tweaks etc tried windows ami, Win 7 , and on my lap even Linux

My cpu is right now not in my pc so if Sb could try start pc without cmos battery would be great

I got my pc to 4different friends (Germany) and they are very far away
But recently I remembered they all had solar Penels

I also tried different sockets I earthed with my water heater in my room (the 3wire )
Then I earthed the pc case
I build a semi faraday cage but soon I’ll build a real one
Also a emi purifier
All it didn’t help and I have also very expressive audio equipment where I have no issue at all
I’ll buy a seperate rod which I can put in the ground and wire to my window to my pc cable
I tried without groud (idk that’s very stupid)

Also to me ps2 lags completely Ingame when I’m in Win ok but Ingame it’s like staying when I move fast
So I Wonder why is it that all my 4cpus have proplems processing data first(real-time)rather than wait with a normal mouse


What helps for me :
-don’t Play high Tick servers eG 128 because it makes it even worse
- play with mouse 125hz same for keyboard
-disable audio in bios and use seperate audio card
-a very low mouse acc makes the hitreg somehow better cause I believe the input gets calculated more and has a higher priority

-disable as many services as u can
-Limit CPU usage process Lasso etc
-change different drivers to high /real-time every time


And don’t ask fiver or other people like me, I wasted a lot of money at least 300for support

And this a long ass answer
But doesn’t even show what I have experienced
And what I have tried -btw sorry for my english

And I’m litterly done but I will sacrefice my fckn life to it and I’ll find a solution... for all of u

I’ll be surprised how much u hit Ingame even when it looks like ur not even on the target cause usually the monitor should lag after xD
same issue 125/250 hz mouse helps a lot when this issue es happen
raw input off
At 2 AM my problem is gone like to 11AM is back (absolutely no sense)
GPU scaling in nvidia panel helps too
lower resolutions helps too

its nice guy, but how many of you think its something with electricity in house? or how many of you think its electro magnetic field, emi from outsite in air...

becouse i think everything in my house is properly grounded, i have solo circuit only for my pc and solo grounded, everything working fine..
but i think its causing EMF/EMI/RFI and attacking LCD monitor display and that is causing our issue. i was testing a lot and i had problems everywhere with my MONITOR.. when i used my PC to other place with strenger monitor everything was smooth and clean.. but alwayse when i plug my monitor to some PC its shit instantly..

We should now focus on how to fucking shield lcd monitor himself and try it, and why this have a long time effect on lcd monitor..

I want to share one thing that is very close to problems you guys have here.
For many years my register in CS was bad, desync problems. I was after every possible tweak you can find.
I think that if you are not sending/receiving enough proper data to server, it might act as you are behind game state.

After many tweaks, the most unbelievable thing. Unshielded ethernet cable being close to AC/DC laptop adapter was the final culprit.
Now ethernet cable is far away for this AC/DC adapter and going perpendicularly against any power cables from power bar.
Tested through couple of days. Game was never as consistent as it is now.
For evidence, I checked retransmits - it points to TCP packets, but if TCP packets get lost, UDP can too, and you won't know it. I don't know why CS didn't pick up any loss, maybe it is impossible to track is such detail, or maybe data was there, but broken? That's why TCP is retransmitting, and UDP sending wrong data? I don't know, but difference is there.

Across all servers in all games I can feel difference. For CSGO difference is like:

BEFORE: Peeking and being shot without ability to react, not being able to hold weirdest angle, spray not connecting, one taps were my best bet
AFTER: Peeking feels right, more time to react. If enemy peeks me and I don't expect it, I am at least able to flick and almost fire, holding weird angles feels normal, spray connects with most if not all bullets, game overall feels not so fast, player models look like they are peeking smoother than before.
I'd like to let everybody knows that i had the same issue as this guy. However, i fixed it by purchasing a PCIe NIC and disabling onboard Audio (I also have a dedicated sound card), onboard LAN and Wi-fi. This is weird because I've had the same issue across two different computers that I've built in the past. Does anyone believe that what I've done would fix an issue like this or is it just placebo?

It won't be just affecting your monitor but your entire setup. Interference can get into the MOBO and cause signal clock errors.

okay tell me then, why i was getting the same problem in same range with strenger PC, on other places, in my friends and lan tournaments, i wasnt using my PC only my monitor and i had the saame problem and same symptoms like in my house, but when i used my PC which i am using in my house on other monitor everything was perfect... idk bro, yeah maybe its affecting entire setup but this problem in games is causing lcd monitor interference

Today i came home from vacation and i plugged out my router before and left my pc plugged in only to a powerstrip
but switched it off... and somehow 2 weeks lata a magical day, today I got no lag, first wingman after 2 week break 9:0 and 10kd how like I got instant uprank idk and if u belive me or not bhop is also doable like i did a very long hop from short to sporn in shortdust the round after and the enemy wrote hvh and toggled the whole game (like rly blatant) cause he thought I scripted wtf

so why should it be ground---like I tried with my water heating loop of my home which is like 80m pipes and a huge water tank and like I also thought why should a 5k$ HiFi just work fine (i swear u can hear it if it isnt )... also tried without the ground wire in my pc and its the exactly same like its not worse and if it was ground it would be worse so...
btw I also use a very good shielded twisted and grounded cable to my pc, and a also sometimes its ok so why u always use the same cables through ur house so they don't change why should the ground get better or worse also deep in the night when u sleep u play better than when ur fit why should it get better by night

and if its ground than its not ur house or ur cables if so than its the pc by itself like i had a lagfree night when I swapped with new custom cables idk if it was just lucky or if it makes sense and i remember swapping my mainboard also exact same time so I had less work...
like the motherboard ground is wasted, or the pc cables like one small pice burnt like the ground pin of a cable like i saw burnt cables in the web and all this could be from a spike
(i rly dont know much about the different pins but ill research) so mb we play with non grounded devices, when i touch my lap for office (3070 should be gameable) i get often a spike when i touch the metal but thats only for my one laptop

like ofc solar is off at night but why so late, my dad kind of sells them as a company and he told me ofc like there these cheap inverters when u use them at home etc but they dont have a battery so why so late and not instant when sun is off...
also not all of u have solar panels

,,,also he told me when they got in the house they had a strange electric guy who did it like crap
there isn't even a layout of electric wires in this house

but why should it happen when I'm at my grandmas apartment - its like brand new and was build by a known company

like mb my devices are damage SO: if sb of u gets a brand new pc completely everything new they should test it at a also relatively new house etc or a puplic place where u can be sure its good ...eg a school before u take it home

tomorrow ill build a huge faraday cage mb around monitor also, btw i also will put sth under pc so its perfect isolated like some wood etc ill post pics
so we can exclude waves

I also searched if there like twisted motherboard cables or if i can shield them separate
sb else wrote sth with that fan can cause it but not for me i disabled them all and run only with my 2 pumps
but why should a pc create emi from sth to itself and the next magical day work just fine

like at these days everything is good so ur pc is fast af and fine
I get it offline, I get it even with powerline with lan and with very fast wifi 20mby download over wifi so i exclude my router idk for me???
Also dont do msi mode, hpet etc i tried so much dont even do that shit that only speeds up ur pc input but not the fckn problem its hitreg and massive delay
like look these old videos from pro gamers {they had so much delay and like 75hz but they were so good because their bullet did connect so dont worry about these tweaks at first}
and if u do tweaks try to find sth with usb inputs

and im not sure about emi from the power - some of u wrote a purifier makes a difference for others not at all like me
it might be a problem for many but why should all houses of my friends etc be like trashed with emi and dont even feel it//see lata they all play higher dpi???
but recently i wrote sth if cables aren't correctly lied in houses they can add up emi by each other or if corecctly they balance each other out like a twisted cable

and its not language or accounts i tried so much even an us keyboard the 4rth and win full eng

---------------------------------------
and to fix we need like to find our same things: get to the source //like u can add me on steam so we can communicate

eg what's ur EDpi? for me its 296
-i tried higher like 1000edpi and it felt kind of better like the problem with hitreg wasn't rly there
so 296 is prob way less calculation and so Realtime performance mb it gets calculated to late somehow so u see the bullets but for the server it makes no sense what he receives because eg in csgo the bullet animation isn't the bullet like u can see it fly but for the server its just a dot and a calculation and its instant there no time. Or u have them like calculated but the pc puts it too late in the game so even offline because in win ur mouse seems fine but mb is has a low q to go to the game files or game selected ram ???

also it could be from neighbors because when i try powerline for my sister it instant crashes after 15 min and the router turns it self off idk why I wrote in the web it can be from overlapping power loops eg neighbor's etc etc
-so do u got any powerline problems etc???

-also is ur pc standing on like a wood floor like for me, or is it like on a stone etc idk //sounds crazy but for high end audio some say its important idk if its guru washi washi shit like there cable holders

-get a voltmeter and check if the voltage changes like late night when nb is wake it is mb higher because in Germany it changes +-10v (max legal limit) like mb a power stabilizer is better than a filter (eg the t.racks Power Con­di­tioner 12 since a while I think of buying it) ? idk some of u wrote about ups batteries etc but idk it would be great if u could measure the exact output voltage
THIS COULD MAKE SENSE: like ill do this for a whole week and write it down as often as I can
so mbmbmbmbmb we could fix it with buying a limiter board and a step up board for cheap or its mb included in some of the power purifiers

...i hate writing much but i hate lag
128tick is horror. Livening in Germany.

What helps for me :
-don’t Play high Tick servers eG 128 because it makes it even worse
- play with mouse 125hz same for keyboard
-disable audio in bios and use seperate audio card
-a very low mouse acc makes the hitreg somehow better cause I believe the input gets calculated more and has a higher priority
-use single core in games
-rawinput off for me it’s better
-late night problem gets less like at 3am
-low FPS and low hz better
-when one core over 50 percent it usually gets worse
-watch if ur cores are like Changeing and not like more static that some cores are near 0 usage always (ofc first cores are higher all time)

I’ll be surprised how much u hit Ingame even when it looks like ur not even on the target cause usually the monitor should lag after xD
same issue 125/250 hz mouse helps a lot when this issue es happen

GPU scaling in nvidia panel helps too
lower resolutions helps too
Try to re install the system. I re installed and used win10 1903 yesterday. I feel very different and stable. I have the same experience as you. The mouse of 20h2 system is very unstable.

Did you disable these things via bios, device manager in windows, or both? This solution cracks my curiosity.
