7/11
A handful of them were fairly hard for me to pinpoint - and even 2 of the 7 I got correct it took me a couple plays of the video to finally notice it.
I mean, I can notice the difference in general, but then I wonder when playing games: Do I notice the difference when I don't have 60fps as an option?
As an example, I really am enjoying Shadow of Mordor on my Xbox One. I know in the back of my head it's running at 30fps and that I could have had 60 fps on my gaming PC, but when I don't actually have the option on the platform I am playing on, I practically forget about it.
I wonder if this is why 30 FPS doesn't bother me on home consoles. When you don't have the 60 FPS option, there is nothing jarring about it. IT's only jarring when moving from the same game at 60fps on your PC. As in, if I had been playing SoM on my PC first, then on a friends console, I would notice a difference.
This is where I begin to draw the line in the sand: Yes, 60 fps is better than 30 fps. There is no doubt in this - even for the people that can't see it, it still improves the experience for them even if they can't tell. Would love for it to be standard.
However, when the only option on the platform you play on is 30 fps, does it end up bothering you, even if you prefer 60 fps? I don't think it does. It certainly doesn't for me, and when I had resolution whores (some of my PC gaming buddies) over to see the game - they couldn't tell it was running at 30fps. It's one of those: When you can't see the better version, it doesn't bother you.
As an example, because 60 fps is the standard on Mario Kart 8, I do notice the difference between 1 and 2 players... and 3 and 4 (when it drops to 30fps). It's still playable, sure, but not quite as smooth.
