I beelieve there is a certain limit to how high of an FPS your eyes can see in.
I haven't really cared for HD or 60 FPS. The most I turn the quality on YouTube vids is 720 (I believe that's what it is).
My vision has gotten progressively worse. I can't see people's faces clearly from beyond about 10 feet away from me. Everything eventually turns into a blur. I think it's interesting that I need intervention to help see things the way everybody else does. I see my world differently than many people without glasses. It is more blurry. The slight details get erased when I take off my glasses.
One time I was over at my friends house. They were watching a show, and two characters were lying in a meadow. After focusing on them, the camera switched to include the landscape. It was freaking beautiful... but at first I didn't even believe what I was seeing. Granted, it was probably the work of some movie magic, but I bet you somebody else wouldn't have doubted its beauty.
Now, I find it a bit weird that we can make more things beautiful than nature itself, although I do know that sometimes things are untouched and I'm just seeing it in a better quality. But hey, what am I gonna do. Sorry this post is kind of long, just wanted to share my thoughts.
