Input lag desync PC and console

[bluca9211]

Hi guys, I’ve been dealing with these issues—desync and input lag—for about 3 years now, across both console and PC.
I’ve gone through 3 brand-new PCs and 3 monitors (two Samsung Odyssey G4s and an MSI G274QPX, all 240Hz), along with countless keyboards, mice, and mousepads. I even bought an Xbox Series X, but I experience the exact same sense of lag that I’ve always had on my PC.
Every mouse I’ve tried exhibits the same freezing, both on the desktop and in-game. In games, the sensitivity feels completely off; it’s as if there’s some kind of "gravity" affecting recoil control in FPS titles—making it impossible to adjust—which is something I never experienced before this problem started.
I’ve run various tests, though I’m not sure how clear it is in the videos I’ve posted: https://youtube.com/@salvocovato5309?si ... ceZD0bdH2u

Only thing that worked for me was lifep04 battery, too much work trying to move house and hopefully find a place without the dirty electricity issue
