Hi heres a TLDR of my problem

New computer build
Mysterious input lag / screen tear every few seconds at stable 240 fps
It gets worst if i have youtube playing on the 2nd monitor (feels like 40-60 fps)
Tried multiple nvidia firmware and DDU
Tried to disable OC and running on stock freq
Tried different cables / adapter eg (hdmi to display port)
Tried multiple windows reinstall
Tried running on one screen
Tried upgrading to the newest windows
Tried using game optimizer provided by MSI / Gigabyte

I am at my wits end. Can my Crucial P1 1TB nvme be the source of this issue? This is my first time using something like this as I have always gone for the Samsung Evo 860, never had a problem then. Or can it be the new OS? Are there anyway to obtain a 2018 version of Windows 10 before the major update?
