People seemingly care more about fps this generation than prior ones. When my 8 y/o nephew refuses to play horizon forbidden west at 30 fps because performance mode is smoother it says a lot. And it's his friends as well. Though that could be because their parents are possibly gaming enthusiasts so those kids they're more exposed. But still, hearing kids talk about performance mode being best tells me fps matter to them more than the shiny graphics.
It may be that 1% are the most vocal. They're also highly influential in getting others to take care and notice. Maybe not all others but enough to warrant us having this discussion on the forum.
I think the opportunity to directly compare 30 vs 60 has a lot to do with it. Classic case of you didn’t know what you were missing before. A lot more game let you play in both modes now so it’s easier to notice how much 30 sucks.
