So the problem for us was coming from a change that power company made it in 2016 in our houses.. they have changed our electric meter from inside house to outside wall with a newer one.The problem was this new electric meter transforms the electricity into some frequency that can be readed by the processor they have..because of the mount position on the wall of this meter that frequency enter into electric wires that are in the wall, but not only that its also in the air affecting.To resolve this problem we called our company power and asked them to move this thing away, they put it into my yard 10 meters away, thats it! never felt this good gaming experience at my home since good old days.
Why is this desynchronization better at night? and the problem seems to be diminishing?
The fact is that at night, the amount of electricity consumed is much lower than during the day, so that power plants can afford to supply electricity at a lower price. This trend is also taken into account by an electricity meter so this mean less frequency.
