I get very bored with these debates, and usually skip over them.

Whisper paraphrases well here:

Might help with your understanding of the whole fps issue. 220fps+ is detectable by the human eye. Personally, I used to be able to tell 85 from 100 easily enough. Maybe not so much now, as I'm older and no longer have the kit to do it with.
Cheers.
