Persistent input lag. Desync, graphical blurriness

[desyncdude]

Ever since building my first PC, now onto my 3rd, which I poured 3000$ into, ive faced persistent issues which have existed across all builds, including a prebuilt I got for comparison. All of them had the same symptoms, which includes input lag that gets worse over time after startup, graphical artifacts like aliasing, flickering textures, moving textures, blurriness especially when moving, desync in online games, and hit reg issues occasionally.

Now, at this point I had also replaced peripherals and monitor several times, formatted my PC several times, played with settings and optimizing everything, all to no avail. I began to realize that from a logical standpoint, the issue has to be caused by something beyond the PC itself or the peripherals. It was either some internet issue or electric. Now for the internet ive monitored packets, ping, jitter, download and upload speed and they all seem to be excellent, so that leaves me with the issue by deduction being in the realm of electricity.

Ive suspected for a while that there might be an electric issue in the house as the house I live in had not been inspected in 30 years before I was even born. Also lights in kitchen go out frequently and i observed my dad replacing lightbulbs in kitchen around 5 times in a single year. I brought an electrician who found that the ground rod was disconnected from the main copper cable which he reconnected it. And he wrote in his report that the main service panel was in bad condition with frayed, damaged or old wires that needed to be replaced.

I was quoted around 8,000$ usd to fix these and my dad basically said F no, and refuses to fix this. So im left wondering if its even worth contemplating paying this much for the *maybe* or possibility that this will fix my issues. What do you guys think? Am I crazy for considering electrical issues as being a cause? Ive asked IT centers near me like computer repair shops and at least 1 person has told me they dont believe electricity is the cause.

I dont know what to believe and I dont know much about electricity to comment on what could be wrong. Voltages with a multimeter read normal from H/N and N/G and also H/G but then again theres more to electricity than just outlet readings.

Best you can try is turn off everything in the house. Connect the PC to the socket that is close to main panel. If that will help than you can decide if that 8k is worth it.

Go to a Gaming Cafe or Friends who play normal. I had exactly same symptons, same thinking like you and in the end i am causing this desync somehow with my body, eyes or whatever.

I went to 20+ Locations, invited talented Players to my House and they played like normal. They had so much time to react, while when i sit on the chair i have like 0,5 sec delay…
