Banjo Tooies low inconsistent frame rate actually gave me trouble as a kid even. But really, the older I got, the more trouble I got with handling low framerates overall.
And overall 60 fps just looks better. Just look at nintendos WiiU games, like Bayonetta 2 and Mario Kart. 60fps just makes it look smoother!
My main problem is also the PC here, since I am pretty close to the screen, and low FPSes on a close screen are killing my head
