I had ever-worsening input lag issues on my daily-driver ubuntu-based laptop for a couple of years. I tried a bunch of finnicky things, with very little benefit. Then I switched to xanmod kernel. It was like I had an entirely new machine. It's remarkable. I kind of wish most newbie-friendly desktop environments recommended installing it on setup (it's easy to do via package manager.)
