Anyone that has done mushrooms can tell you that seeing the world at the frame rate that the brain is capable of processing is a load of fun. I have no idea how psilocybin affects the visual processing center of the brain -- or hell, it may affect the eye itself, what I do know is stepping out into a room and looking around without the brain discarding the frames that it doesn't feel like processing is amazing. However, it does look completely fake. It is too clear / crisp. Our brains aren't used to seeing every little change -- they discard information. So, if you are watching a movie at 48 or 60fps, it looks fake is the best way I can describe it. That is because when you are looking at the screen, you have a central place to focus, and my guess is the brain doesn't discard information if you aren't moving.
Again, this is just my guess, but I think the reason video games look much better at high frame rates is the fact that they already don't look realistic. We are expecting really crisp, sharp, fast graphics. Literally -- it is all in your mind.
As a test, pan your head from left to right and notice the "jumpiness" that is reality. Now, eat about a half gram of shrooms, and do the same thing. It is no longer jumpy, and you get a REAL smooth pan.
