Again, these people are only the minority hardcore gamers.
The casual majority gamers don't care for framerate or resolution and use 1080p 60hz screens
Yeah. Most wont even know what fps is.
The older I get the less I care about fps. Once it gets beyond 60 my eyes are more than happy.
I never cared. As long as it feels smooth enough, I am happy. Never played competitively to care. Most people that care are usually into some kind of first person shooter like COD, Battlefield, Counter Strike, PUBG, Overwatch etc.
I enjoy single player story games mainly, together with strategy games. For that 60fps is more than enough. So rest of the grunt I like to stick into image quality, aka 4K goodness
Over the years what do people buy new consoles or graphics cards for mainly? Graphics. That is what I like and 4K offers better graphics than 1440p. If it did not believe me I would much rather a lower resolution as it would mean I can get away with spending less on GPU’s.
