We have failed in our neglect to follow BASIC Computer Building standards. No one cares about properly grounding the INSIDE of their PC; The critical issue is that there is nowhere for RF and leak voltage to return to the ground/return of the power supply, without forcing back through the entire motherboard, then up to the 24 pin and 4+4 pin/video card 6+2pin. This could be why your 5000$ RTX 4090 i9 Ryzen 7950 X3D PC cannot beat a potato office PC that someone put a GTX 1060 in per input lag. In this how to tutorial, we will reduce that.
This then ends up in your mouse and keyboard input lines, your GPU data lines, errors in the data busses resulting in resends; resulting in extra desync and input lag where it should have none at all. I propose that this is the reason why changing some random load lines and voltages in bios, can sometimes drastically temporarily change the input lag of a pc, or where changing the ram timings can work for around 2-3 boots before going back to the…
