I've been playing CS2 since its release. Everything was fine, my aim was perfect, the mouse felt like an extension of my hand. 10,000 hours, 4,000 ELO. Then I moved to a new apartment and things started to go wrong. My game level dropped, something was off, and I thought maybe I was sitting in an unusual position. I brought back an old chair and table, but something was still wrong. The mouse was a ♥♥♥♥♥♥♥ piece of junk, so heavy I couldn't hit anything. I started looking into the issue and realized I had input lag. I optimized Windows, updated the BIOS, tried different settings, etc., but nothing helped. I spent days trying to figure it out, and my wife was already asking, "What's wrong with you?" I said, "I have input lag. I'm splitting the video card and the USB port on the mouse into different processor cores." She was wary. Then I started spending my entire salary on various mouse pads, mice, keyboards, power cords, outlets, UPSs, and even changed the wiring and the electrical panel. It didn't help. One day, my wife comes home and I'm playing with the iron on. She asks, "Why didn't you turn it off?" I tell her there's no input lag with my iron. She says I'm completely nuts. Then I bought a generator and installed it outside, everything is superb. There's no input lag. I played like that for a few days and was convinced he wouldn't come back. The neighbors looked at me askance, my wife was getting a divorce, and one neighbor even called the police. I decided to move. I'm going to take out a mortgage. I had to search for a long time, playing around with my computer and monitor, connecting and checking everything, and the realtors were incredulous. I found one that was perfectly fine. When I arrived to sign the contract, I immediately ordered it to be illuminated, and then the thought occurred to me: could the apartment be infected with input lag from the computer? I called a friend to clarify the issue. My wife and the realtor quietly called the madhouse, and they took me away. I've messed up my phone here, writing a comment. By the way, there are a lot of input lags here, all the guys are fine, only one duplicitous devil backed up, said there was no input lag, and they let him go.
