I can personally confirm Electromagnetic Interference (EMI) can sometimes be a source of lag/stutters -- it's also frustratingly wild goose chases for red herring very often -- but we've seen another forum member successfully fix things by fixing EMI.

Actual Success Story Reply by Chief Blur Buster
NOTE: EMI is a very rare cause of lag/stutters. Literally like 1 in 100 chance type cause. But cause exists. We've seen forum members fix lag via EMI fixes. It is very hard to troubleshoot, requires expert-league troubleshooting skills. However we've had actual confirmations of fixing EMI to fix stutters/lag. The short story is that computers are now full of error correction behaviours, and electromagnetic interference can slow down many electronics via error floods that is continually corrected by error correction, slowing things down. This includes SATA buses, PCI buses, M.2 buses, Ethernet cables, ECC RAM, and lots of other error correcting layers. Massive EMI can slow down a computer noticeably enough to create EMI-related latency.

so if you have a timer (frequency generator) fucked up, what the computer records in terms of the duration of each frame is not what you see on the screen
you have 100 frames going, each one is 5ms exactly, but because the timer is not stable, 1 intra-computer ms can last 15 real physical ms for several of these 100 frames - 5, 5, 5, 15, 5, 5 , 5...
for you it will be a stater, and it won't show up on the video, so it won't show up in the afterburner and so on
there is a tool from mikrosoft for deep trabshooting these things, it can show you on a micro level what's going on in the system
each sub process how many nanoseconds it took in which process, all the connections between drivers, software and everything in the system
and there are such voids in the events. milliseconds when time stops for the computer, but the computer does not understand that this gap existed
at these moments the mouse does not move
it's a tool for developers of drivers and firmware for hardware, mostly
there are a couple of people who know how to use it, but the results themselves do not explain the causes
the tool can directly look at mouse data and see how it is intermittent if you have an intuition. but in reality, the mouse is running fine, but the computer time is stopped at ms or ms, and the user suffers because of the pause
the point is that the computer does not understand that the logical time is paused / unstable, for him everything goes on continuously
