[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.

No, rgb, cooling etc. has nothing to do with this.

So you are living in a new location now? There exists a rumour, that your pc got "bad" from being exposed to emi in the old location, the solution would be again getting a new pc and monitor etc., but only do this if you can buy and return everything easily.

I just wanted to add my point of view here.

When I was a pro player (CS1.6) I still remember our team configs, Pentium 4 running at 3Ghz with 8GB Ram (OCZ) and Geforce 4 and mouse was the Logitech MX300. We had an aluminum case where sometimes we get shocked when we touch certain parts but otherwise I can remember input lag-wise, we did not have any issues.

I haven't played FPS for years and I started to play Valorant since the beta, today I'm 36, and Ascendant is 3 in rank. In the beginning, I had an i7 8086k, 16GB Ram, 1080ti, 1 SSD, and 4 HDD, Full of RGB, and my connection Cable (coax) was 900 down and 100 up. I did not have a floaty mouse issue but more like how to find my CS resolution but I never found a real fix to it and I got used to it. The issues that I had were
- I am unable to peek angles, no matter how is my approach, even if I Ferrari peek style the enemy will shoot me as soon as I see a pixel of their shoulder.
- I am unable to hold angles, well if peeking is already a battle for me, holding is just game over, even a Bronze player will treat me like it was a mistake for me to play this game.
I tried to change the modem, cable type, and cable length, and add more speed to my internet by upgrading my subscription with ISP but nothing helped.

I noticed that in my duo when he plays, he has time to peek and adjust the crosshair on his head and shoot and he is freaking SLOW! 1v1 custom game he can't even beat me in a face-to-face fight. Then I realized he had AMD CPU and I was like it's probably time to change hardware.

I got a new PC, 5950x, Asus X570 Hero, 32 Gb Ram, PSU Corsair HX850 and RTX3090, and I did remember right after installing windows, I did not even when to install any drivers (well Windows did auto-install NVidia driver), jump in Valorant range and that feeling when you click and you insta hit the bot and went to DM, the game was fast, did wake up my brain, peek was legendary I was 40 kills while the second person was at 19 and he was Immortal3. Then installed all drivers (Audio, AMD Chipset, Nvidia Drivers) and the issue came back! I thought it was my connection for sure so I decided to move where a Fibre connection is available.

I did move and my ping in Valorant is even better but still feel like crap! and now I have a floaty mouse! on my 2 gaming mice!

My questions are, do you think all the RGB on my fans, ram, AIO, and GPU could cause this?
I thought my HDD could be the cause by removing all of them but the issue is still the same.
Do you think the water pump on AIOs could be a culprit?

I haven't done any electric testing yet, my next goal is to get an EMI meter and see what I get. Does lowering EMI from house electricity should help, if not then where the heck is this coming from? Must be inside the PC itself or Windows!
Well, since you are talking about Valorant specifically, I might be able to suggest a few things, since it's my main game at the moment.

I would not bother looking into electrical/EMI issues yet. There are tons of things to troubleshoot (especially for Valorant) that are much more likely to cause lag than the extremely rare cases of real electrical issues.

My thoughts/suggestions:

-Since you mentioned no lag before installing drivers, there might be an issue with overwriting, updating certain drivers (conflicts between Windows automatically installed drivers and manually updated drivers). Try clean installing Windows again from a USB stick, not the "reset my pc" option. But, this time, unplug your ethernet/wifi to stop automatic driver updates. Keep your Chipset, GPU, Audio, Network drivers on another USB stick and install those first, BEFORE running Windows update on the newly installed OS. I have not tried this but have seen it recommended in other forums.

-Your PC might need a PSU upgrade. 850W for a 3090 + 5950 might not be enough. Technically, it might be within the expected power draw of your components, but I've read that the 30-series GPUs could have power spikes, which would prob cross your PSU's capabilities.

-Certain tweaks/OS/Bios settings can completely brick Valorant. Valorant seems especially sensitive to certain changes, so if you have applied some of the tweaks recommended found in a lot of those random youtube "optimization" videos, Valorant will start to act wonky. With your hardware, you shouldn't have to worry about boosting FPS/performance. The bigger concern is to go for stability/consistent performance. So, it's better to leave most things the way the OS sets them by default.

-Certain background programs/bloatware are known to kill Valorant performance (drop fps, introduce stutters, desync). Asus AISuite + Armory Crate are known to do this. Even uninstalling them does NOT fix the issue. Will have to clean reinstall Windows and avoid installing these in the future.

-Try Windows 10. Ryzen systems + Win 11 sometimes leads to issues with Valorant.

-Lastly, based on your new PC, it seems that you are willing to splurge a bit on gaming. I'd consider getting your PC optimized specifically for Valorant. Usually I'm against "optimizers", and those sorts of services, but COMPREADY seems to have a very good rep when it comes to optimizing specifically for Valorant. I've heard they spend extra time on diagnosing/fixing strange issues that come up on a case-by-case basis. Since it looks like you are about to go down the rabbit hole of EMI/electrical issues, which not only gets expensive, but- most of the time- doesn't yield any useful results, I'd suggest just purchasing an optimization before doing that.

For 99,9% ppl these automatic updates/drivers instal work just fine( and they do it once in 5years) but for us there may be something wrong: do you realy belive that?

99.9% of people do not care or notice the type of issues we discuss in this forum. To them, a working computer can turn on, search google, watch youtube, send emails, shop on Amazon, etc.

Let anyone else in my family use my desktop PC, they will say it works perfectly fine! It's "fast", right? (NVME+Gigabit Fiber)
But unless you know how things are supposed to feel ingame (when competitive games run smoothly), you'd never notice anything is off.

For us, any sort of delay, micro-stutter, desync, sluggishness is a big deal when it comes to competitive games.

And yes, driver updates/reinstalls is still a wonky process. It's not as bad as it used to be, but still not as clean a process as I would like it to be. AMD chipset drivers don't always successfully install, and sometimes have issues when previous versions have been installed. Similarly, there is a reason DDU exists, and why it is generally recommended to use it when updating GPU drivers.

Hey @Shade7 thanks for the tips!

This is a brand new one because my ex 1000w gave up on me and HX850 was the one recommended to me based on my current config!

I am currently on Windows 11 latest build and for the last 2 weeks, I probably reinstalled Windows ten times :x

I have GSkill RGB rams and in order for me to turn it off I have to use those Armory Crate or the new things to control all RGB is SignalRGB

Each Windows 11 installed forced me to have an internet connection otherwise I can't continue the installation

Yes, I did try all the crap on how to lower input lag blablabla regedit process lasso HPET to the left optimize network to the right, and yeah I feel like staying default would be wise.

At some point, I thought it was a network issue I did build a Pfsense box where my ISP fiber optic goes into it and another fiber optic goes into my PC... Still can't peek people, they always see me before I see them and in order to survive I have to get an inhuman reaction.

How come Windows 11 mess up Valorant? Damn I don't want to go back to Win10 but I guess I will try it in a bit and I will let you know my findings

Is there a way I can add you on discord? Are you playing in NA?

Well, since you are talking about Valorant specifically, I might be able to suggest a few things, since it's my main game at the moment.

I would not bother looking into electrical/EMI issues yet. There are tons of things to troubleshoot (especially for Valorant) that are much more likely to cause lag than the extremely rare cases of real electrical issues.

My thoughts/suggestions:

-Since you mentioned no lag before installing drivers, there might be an issue with overwriting, updating certain drivers (conflicts between Windows automatically installed drivers and manually updated drivers). Try clean installing Windows again from a USB stick, not the "reset my pc" option. But, this time, unplug your ethernet/wifi to stop automatic driver updates. Keep your Chipset, GPU, Audio, Network drivers on another USB stick and install those first, BEFORE running Windows update on the newly installed OS. I have not tried this but have seen it recommended in other forums.

-Your PC might need a PSU upgrade. 850W for a 3090 + 5950 might not be enough. Technically, it might be within the expected power draw of your components, but I've read that the 30-series GPUs could have power spikes, which would prob cross your PSU's capabilities.

-Certain tweaks/OS/Bios settings can completely brick Valorant. Valorant seems especially sensitive to certain changes, so if you have applied some of the tweaks recommended found in a lot of those random youtube "optimization" videos, Valorant will start to act wonky. With your hardware, you shouldn't have to worry about boosting FPS/performance. The bigger concern is to go for stability/consistent performance. So, it's better to leave most things the way the OS sets them by default.

-Certain background programs/bloatware are known to kill Valorant performance (drop fps, introduce stutters, desync). Asus AISuite + Armory Crate are known to do this. Even uninstalling them does NOT fix the issue. Will have to clean reinstall Windows and avoid installing these in the future.

-Try Windows 10. Ryzen systems + Win 11 sometimes leads to issues with Valorant.

-Lastly, based on your new PC, it seems that you are willing to splurge a bit on gaming. I'd consider getting your PC optimized specifically for Valorant. Usually I'm against "optimizers", and those sorts of services, but COMPREADY seems to have a very good rep when it comes to optimizing specifically for Valorant. I've heard they spend extra time on diagnosing/fixing strange issues that come up on a case-by-case basis. Since it looks like you are about to go down the rabbit hole of EMI/electrical issues, which not only gets expensive, but- most of the time- doesn't yield any useful results, I'd suggest just purchasing an optimization before doing that.
Hey @Shade7 thanks for the tips!

This is a brand new one because my ex 1000w gave up on me and HX850 was the one recommended to me based on my current config!

I am currently on Windows 11 latest build and for the last 2 weeks, I probably reinstalled Windows ten times :x

I have GSkill RGB rams and in order for me to turn it off I have to use those Armory Crate or the new things to control all RGB is SignalRGB

Each Windows 11 installed forced me to have an internet connection otherwise I can't continue the installation

Yes, I did try all the crap on how to lower input lag blablabla regedit process lasso HPET to the left optimize network to the right, and yeah I feel like staying default would be wise.

At some point, I thought it was a network issue I did build a Pfsense box where my ISP fiber optic goes into it and another fiber optic goes into my PC... Still can't peek people, they always see me before I see them and in order to survive I have to get an inhuman reaction.

How come Windows 11 mess up Valorant? Damn I don't want to go back to Win10 but I guess I will try it in a bit and I will let you know my findings

Is there a way I can add you on discord? Are you playing in NA?
I don't think it's Windows 11 related mate, don't waste your time and energy.
What would it be from your opinion? EMI issue?
Idk if its EMI or something else, but it's related to either your home/apartment/building or the whole area you live in. I know one experienced electrician and he told me he tried to help others and battle with this issue before, but only moving to a place where the electricity is done right has worked so far.

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

I get that your family members cant feel input lag as we do thats kinda make sense. Why you get hoked up to the game? It was working since day one - you get new mouse and improve you skill thats not the issue today. No tweeks at all
If you will get rekt in every game you play on your PC since day one you try it i dont belive you will stick to that hobby right?
So 99,9% of gamers dont do system tweeks at all they just play the games. Maybe later on they end up here.

I installed Windows 10 to try out and to be more precise I did install a customer version of if from ggOS. What I can tell is that there version of the OS is very snappy and fast which I like. The other good thing is that mouse house or input wise it's very snappy as well. Matter of fact, I do not have floaty mouse anymore but the issue that remains and I only play Valorant are
  • Hit reg issue
  • Unable to peek corners, enemy will always see me first no matter what and have the feeling they also have time to adjust
  • Unable to hold angles even if you time your shot with footsteps or playing very off angle
Those are my big challenges and it happens at 25ms same as 60ms. Another thing to keep in mind is that I did turn off all the RGBs on my PC from 10 fans, Water block (NZXT X73) and 2 RBG Ram stick
