Ever looked at a CRT monitor with a scan rate of 60Hz? I don't know about you, but I end up wanting to stab my eyes out.
75Hz or higher and everything is cool.
CRT scan has an obnoxious flicker, so animation frames don't need to be as fast to look good, but sub-60 frames are noticeable for a lot of us. Things are pretty tolerable down to 30, but go much past that and your experience will suffer substantially.
I generally consider frame rate to be more important than any other visual attribute. If I'm not getting 30-60 frames, I'll reduce whatever settings I can to get it.
