I do notice the increase in FPS passively in the 24-40 range. Anything above that, I only notice it if I acually play the game, so most comparison videos do little to nothing for me. Especially if the comparison runs at a stable 30FPS the differences are not really visually noticeable to me. I do 'feel' the difference while playing though.
Curiously a higher FPS count in movies and 60 FPS streams with real life footage have a tendency to make me nauseous. I don't get it in games, only video footage.
That being said, as long as the performance is at least a stable 30 FPS I'm not too bothered. Not every game needs 60 FPS imo, certain genres benefit from it immensely, others, not so much.
