The most common reason so many people have input lag problems these days.

I'll keep it as simple as I can.
The reason most of you have input lag is due to a high number of reasons all related to emi, the most common is electrical interference due to poor power factor/high harmonics and grounding.
A common problem people are having is harmonic distortion on their electrical system. Harmonics=elevated electrical and magnetic fields that interact each other, causing eddy currents which increases the resistance of the grounding system which then can cause looping currents within the system. This effect causes common mode and differential mode noise in the electrical system. Which then causes elevated electric and magnetic fields, or simply put, emi. It's an issue in almost every home.
Computers use smps (switch mode power supplies), which rely on capacitors to reduce common mode electrical noise. They work by shunting the noise from hot and neutral to the ground wire. The problem with this is, when you have high resistance on your grounding system the electrical noise shunted by those capacitors no longer travel down the ground wire, they travel through the shields of your cables, your computer case, your floor, ceiling, furnace duct, the air etc etc.. any and all paths of least resistance back to the source.
The effect is ground fault currents, which means elevated electrical fields, that further interact with the magnetic fields that further increases the problem.
This is the reason so many mention their PC running great for the first few minutes to then have the input lag suddenly return. It's the noise from the computer looping through the electrical system, increasing and increasing the electrical noise.
All devices in the electrical system are effected from the effects of this interaction which all further aggravate the situation by dumping their noise in the system.
Not everyones situation is going to be exactly as explained, and not every emi problem is as complicated. But they are almost all related to electrical noise in your electrical system or circuit, and all have solutions.
There is no 1 fix solution, but there is easy, simple things you all can do to improve the problem if not, fix it completely.
Attacking the source of emi instead of trying to mitigate the symptoms is how to properly do it. And it's not as hard as you might think.
There is a lot of solutions to mitigate emi if anyone has any questions.
I can answer a lot of questions and sort any emi problem. I can explain simple tricks to easily identify sources of emi and how you can easily reduce or remove them.
