Rumor: Mario Kart World will have a 120 FPS Mode.

From my own experience (Pennys Big Escape on PS5) I couldn't tell it was 120fps. Just felt like 60 so definitely does vary by person. 

I can definitely tell there's a difference at 120fps. But going from 30 to 60 is like witnessing the birth of your firstborn child. 60 to 120 is like finding out they gave you a free extra chicken wing. Outside of a game like overwatch (with mouse) I've never really cared much about FPS above 60.

120 is nice but I don't think there's ever going to be a time when I boot a game and go "gross it's only 60fps".
