The most complex and illusive PC/Hardware issue I have ever encountered. Mouse/Keyboard input lag related

This problem has been the most difficult to diagnose issue I have ever seen or heard of on a PC. Thought I might get some insight (hopeful) as no one that has the issue has been able to find a real solution as of yet. I anticipate many people will doubt my experiences and the symptoms I have observed. I would doubt someone saying the same things that I am if my PC functioned properly however I have seen what Ive seen and know it is real. For those that are willing to believe what me and others have said on this subject- thank you.

Symptoms:

Input lag across the board in both games and windows, both mouse and keyboard inputs are inconsistent and change over time. At times the dpi increments on my mouse hardly change the sensitivity, other times it adjusts a ton. The monitor display suffers hitches, and micro stutters, of the same varying consistency. Makes game play at 140fps and below look and feel like 60 or lower. Internet webpages load in slowly (blocks of the page load in at a time), you tube videos and twitch buffer at random times with no packet loss. At times the lag is minimal at times its unbearable. The input lag and video hitches seem entirely inconsistent however I have found that nearly any hardware state change/software change can affect it to varying degrees. Everyday, even every hour my mouse feels and tracks differently. Now the really interesting stuff: Practically any hardware/software setting or change I can make to my system will alter the behavior of the mouse/keyboard inputs. Keyboard input is possibly the easiest way to tell as I can change different settings and holding down keys in windows search bar spits the characters out at different speeds. I have posted around many forums and seen many others with the same issue being told its placebo however this is simply not the case. I know a properly functioning PC should not behave this way but my system and others do.

Things I have tried:

3 different PC's (completely different specs) 3 different monitors (120hz, 144hz, 240hz) 5 different mice (Logitech G-Pro x2 models , Razer Deathadder x3 models) 3 different mousepads 3 different keyboards Using different circuits and configurations around the house. (some work better than others, however input lag is still present) Different power strips, power conditioners Tested for outlet grounding with 3 pronged tester.

Things that change the mouse/keyboard behavior and monitors display quality:

Moving the monitor/router/modems/pcs power cord to different outlets, different power strips etc. Note: My Wi-Fi does not even work if my router/modem are on the same outlet/power strip- the signal shows up but no connection. Changing which USB ports the keyboard/mice are plugged into. Applying tinfoil to any power cord, or mice/keyboard USB cables. Applying Ferrite (can mitigate electrical interference) beads to any of the above cords. Changing nearly any BIOS/Windows 10 settings. Adjusting GPU fan/power settings. Adjusting nearly any settings in NVIDIA control panel change the mouse behavior. Applying overclocks, disabling all OCs/turbo/speedstep. Adjusting/propping up the GPU (seems like the positioning changes mouse behavior heavily). Changing case fan profiles- usually lowering fan speed/power is better. Monitor settings (brightness, color, resolution). Placing phone onto the PC case (doubles mouse sensitivity immediately). Changing where the router/modem is or moving the power cords. Separating all cables from each other.

Now the confusing part. All of these problems happens along with some very peculiar wifi issues in the home. To summarize the way in which my router/modem are plugged in (different powerstrips, plug orientation) affect the quality and behaivor of my wifi. Because of this I decided to explore the possibility of my ethernet cable being the source or my PC problems as well. I contacted the ISP to send a guy out- they did and he got a reading on the cable drop for large voltage spikes. He said that the coaxial cable had voltage leeching onto it using the ISP ground block as a path of least resistance. Told me to contact the power company as it was on their end. Well I readup on some similar issues on cable forums and contacted an electrician about a possible loose neutral in the home just to verify it was not from in home faulty wiring, or a television backfeeding voltage or something. He told me the house was good to go and said that the issue was definitely power company. Well I called the power company and they sent out a tech while I was at work and supposedly they fixxed somthing, but the wifi still behaves erratically and of course my PC still suffers this issue. So I took a measurement of the coax cable and found there is still fluctuating voltage on the shielding (measured shielding to ground). Well I am in contact with the power company to hear the official report of what the tech even did here. I did however in the meantime head to a rental our family owns and tested the PC there. Booted up my PC and although my inputs seemed slightly better I could tell they were still messed up. Then I started testing the things Ive tried before- ferrite beads on cables, changing around the power configuration (moving outlet for monitor etc) and any BIOS changes and found that my mouse behaivor is still changing.

Before all of this I thought it has to be something with my houses wiring (floating neutral/ground) or a ground loop being created somewhere, raising the noise floor in the system which in turns causes data loss. However now I am just considering that my PC was damaged in some way that produces these results. Since testing at the 2nd house I have swapped out GPU, RAM, and SSD and my rig functions the exact same. I am not sure if this is a combination of hardware/software bugs or what. If my rig was truly damaged I would think that I would see much more serious affects. All I know is my PC is not functioning properly. There are many others out there with nearly the exact same symptoms (on completely different systems, in completely different parts of the world) but none of them have found a proper solution, just more things that change the behaivor for a time. The input lag always comes back and mouse/keyboard behavior is totally inconsistent. At times it operates nearly perfectly but not for long. Now I have posted my own threads plenty enough as well as read many on this very issue. People tend to say this is placebo, or we are insane to think its possible for all this to be happening. Well I cannot convince you beyond saying that I am fully aware how crazy of an issue it would have to be to transcend entirely different PCs or houses, however the truth is I and others have observed this very behaivor beyond doubt. Many of us questioned ourselves, but when you find that you can actually change the inputs behaivor yourself by doing certain things software/hardware side, you realize how very real it is. Anyway thanks for your time and if you have any doubts that there are others out there with this I recommend you read some of the linked threads below.

You might want to advise a mod to delete the, at least three other identical posts, you created in other sections of this forum. I noticed you did not say anything about possible malware/viruses/technomage infections. Have you been infected? Severe wifi external interference?

i'm going to be brutally honest: more than anything, it sounds like you have schizophrenia.

if you're really sure that you have three completely different computers all bizarrely malfunctioning and displaying drastically different input times, try validating your theory experimentally. modern mobile phones can record 960FPS video - do some button-to-pixel input lag tests at various parts of the day, or whenever you feel like the input lag has changed. if it turns out that the measurements are all pretty much the same, well, PEBKAC.

the only explanation that would even kind of make sense for what you're describing is that some kind of malware is installed on all of your computers. having bad electrical wiring would not cause what you describe. if it happens even after a reformat w/ internet disconnected, very probably a PEBKAC issue.

Infected? I have tested this on multiple PCs and dozens of reformat. As far as the wifi external interference, why would a light bulb affect the wifi and PC behavior?

Ok, so? And you're attributing this to the notion of inconsistent lag of machines? Static friction, environment temperature, your own temperament, different games, mouse feet, hand temperature, ALL are attributes (there's probably more) to how mouse movement can feel.

lol. ok? input lag will always be a thing, from your gpu processing, monitor processing, cpu processing, mouse/kb signal processing, and finally your human reaction time.

You want to be a meme too?

Funny thing is, that r0ach dude wrote all that crap he did, but still used a 60hz monitor (stubbornly so) while there were faster solutions at the time. Doesn't help his credibility.

Yes, i have a real solution: Just chill out dude... If you have a modern GPU/CPU setup set to low latency, and a performance 240hz TN panel (with frame rates actually hitting 240), whatever lag you think you're perceiving is in your head.

Well like I said I knew people would showup calling me schizophrenic and trying to tell me its all in my head. I fully realize environmental factors can affect the "feel" in the way you say. That level of input lag is not at all what I am referring to here, I am speaking about input lag that is much more pronounced than any of that. Anyway its clear you would rather call me crazy than even entertain the idea that there is a real issue here so carry on.

Well if you do not want us to perceive you that way, then by all means record and send us some super high frame rate recordings attributing to the input latency you are describing, as said by post #4 in this thread.

Cuz right now, it just seems you're stating the obvious issues that everyone has that no one can do anything about due to the limitations of our hardware. Unless you actually have a discernible amount of input latency that is a lot higher than the norm, then please show us that via a video or a form of test.

Incandescent and LED bulbs can effect your wifi router. Any unshielded wiring really.
