[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.

If you have input lag issues then changing PSU with better EMI filter will not help. Source of this problem is not in the range of regular PSU EMI filter.

I changed the power supply to chieftec gps 700a8 i have higher input lag than psu silentiumpc 550w m2 gold, more power the power supply increases the emi noise? whether the 12v line can cause delays? Image 8pin Voltage drop to 11v

your new psu does not provide power that is as clean as the previous one does.

Did someone tried the torus power Toroidal stuff ? Its quiet expensive like 2k+, it says "Torus Power
products restore incoming power to its clean original state". Maybe i give it a try.... have suffered from this problem for too long 6 years bad daytime better at night.

i also switched to from cv650 to hx750 modular with multi-rail support. it makes no difference, from hw side for me having fclk 400 really helps it makes my hit registry and recoil much much better. however just to support that theory that electricity has affect on inputs i came with two videos that proves it.
in the first video i show how my display which is dell alienware aw2518hf 240 hz , 0.5ms monitor restarts and shows error message "
.Unsupported audio format. Please set the audio output on your aido player to Pulse-code modulaton (PCM) if avaiable
when i move with my electrical blinds. Doesnt happen if monitor is on UPS (which has double-conversion) or if i use displayport ( this was recorded on hdmi 2.1). So now victor910 tell us again how this is server sided input lag and electricity is no factor here. Just to reply you let me quote
"victor910 Input lag" manipulation coming in 2002 with cs 1.5, not 2009.
Perfect recoil with 60 fps I'm explained before, take pills Guys and reading carefully what I wrote before.
I'm really wanna help you, but just today ;)
i wasnt talking about hardware-software optimalization guides , i was talking about first thread where the guy called "schoof" completely described this issue, it was not the classic input like when you have vertical synchronization or on or difference between pre-rendered frames 1vs3, he described how everything is hard to suddenly, he told about things like how duck jumping and bunny hoping became impossible, how keyboard pressed is delayed so you cant strafe, how you cant track because mouse feels very heavy, floaty and unprecise even on good fps and good gaming monitor. it seems like the more you want try to track enemies the mouse feels more off and delayed instead.Its not classic input lag.
Here is video 1 https://www.youtube.com/watch?v=1omXnZ7AA80.
In video 2 i recorder electrical buzz everytime i touch my keyboard , it also records activity like loading or sometimes mouse clicks.
https://www.youtube.com/watch?v=Ehpj9IR4EGw its most hearable at 0:45, 1:00 or 1:15

So a while ago I bought some Tacima mains conditioners from amazon, 2 of them, and plugged them both into my socket extension, where my PC and monitor are plugged in. I gave it a few days, didn't feel anything, but I found out I was able to overclock my GPU (2060 super) by +100mhz (1650 to 1750) which was nice.

I currently have my computer grounded to an old rusty steel rod outside my house, I'm going to replace it soon and am wondering if replacing it with a nice new copper grounding rod will do anything.
