It's strange hearing reports of "scroll lag" in the other comments. It's possible I'm just lucky. Or there's a misconfiguration somewhere in their setup that Chrome somehow avoids.
It's true that I still mostly use Chrome for webdev - I've become more used to it's (excellent) dev tools, even though Firefox and Firebug started that whole trend. It feels very right to separate my "user browser" from my "dev browser" in this way!
Don't forget the other possibility: someone using Firefox having internalized this lag as "normal behavior".
Have some humility.
That said, there is something to be said for modern applications just running way below the limits of the refresh rate of our screens: https://twitter.com/jmmv/status/1671670996921896960
In the next tweet he compares it to a stock Surface Go 2 (quad-core i5 processor at 2.4GHz, 8GB RAM, SSD) and seems to be surprised that it performs like crap. His 600MHz CPU is sufficient to get decent input lag from NT 3.51 which lists a 25 MHz CPU as it's minimum spec just as my machines get decent input lag from Windows/macOS which list a 1.2 GHz CPU as the minimum spec.
I know clock speed is a bad metric, but you get the point. Your hardware needs to be well above the minimum spec by an order of magnitude if you want acceptable latency
