Then etymologically.
Anyway, to answer your question, probably only to blind people 30fps and 60fs are the same
What do you mean with "60hz precision gameplay"?
Input lag is reduce at 60fps but AFAIK 60fps don't make controls more precise/accurate.
AFAIK dead-zone in the controller don't change at 30fps or 60fps.
Correct me if I am wrong of course.
The study i posted in this thread found that you are more accurate at higher frame rates.
