I can't agree with this. I've been gaming at 60 FPS on PC for at least 10 years, but I can easily adjust to 30 FPS when playing console exclusives. I genuinely feel bad for people who can't adjust with ease.
I've always been fairly dubious of the people who claim to be "unable" to play games at 30fps, simply because they have experienced 60 to some greater or lesser degree.
I mean, is there any medical research into this syndrome they develop where 30fps makes them feel sick, uncomfortable, causes eye strain or makes the game unplayable for whatever reason?
We've all played games at 60fps, even on consoles, so why don't we all develop this syndrome?
How many hours, and what exposure does it take to develop the syndrome? How come many people who play almost exclusively on PC at 60fps don't develop the syndrome, while others do?
Is the syndrome permanent or temporary? How long does it last?
What is the physiological basis for the syndrome? Or is it purely psychosomatic?
Why does the syndrome not affect them whilst watching sub 60fps non-game content, like movies which are 24fps (and no, motion sickness doesn't count as it only applies to first person perspective, not 3rd person and many suffers attest it affects all games)?
Why are only PC users affected (from what I can see), while people who play primarily Nintendo console exclusive games are not affected despite both being 60fps? Or people who play 1000s of hours of 60fps beat 'em ups on console not affected while PC users are?
There's an interesting study in this...
