Reminds me I was playing games at 320x240 and then going to 1024x768 resolution. Suddenly everything started looking "basic", whereas at lower resolution, brain could somewhat "fill in the blanks" so to speak so it felt better.
I guess it is similar for higher frame rates - it just shows the shortcomings.
I think if the film industry committed to higher frame rates we would have seen massive improvements over the years.
I think 48 fps gains more detail but makes things look cheaper. The Hobbit looked like a BBC TV show compared to LOTR. That said, I don't pay enough attention to film these days so maybe people have gotten better at it and I'm watching 48 fps all the time.
