That may be an issue of going from a CRT tv to an LCD tv. As far as I am aware there was no software manipulation of the video input on a CRT. It just took the input and displayed it on the screen in the only way it could. Newer tvs have all kinds of settings to alter the video which takes processing time. They also typically have a game mode to turn off as much of it as it will allow.

Why should the user care whether the lag is introduced by the software in the controller, or the software in the gaming console, or the software in the tv.

The lag is due to some software. So the problem is with how software engineering as a field functions.

I hear it claimed that you're only supposed to enable game mode for competitive multiplayer games -- but I've found that many single player games like Sword Art Online: Fatal Bullet are unplayable without game mode enabled.

It could be my unusual nervous system. I'm really good at rhythm games, often clearing a level on my first try and amazing friends who can beat me at other genres. But when I was playing League of Legends, which isn't very twitchy, it seemed like I would just get hit and there was nothing I could do about it when I played on a "gaming" laptop but found I could succeed at the game when I hooked up an external monitor. I ran a clock and took pictures showing that the external monitor was 30ms faster than the built-in monitor.

It’s not just the software, the analog electronics of LCD/LED screens are inherently laggy and have motion blur: https://en.wikipedia.org/wiki/Sample_and_hold
