60fps isn't high enough for realistic motion. 60fps on a sample-and-hold display gives you obvious blur, and 60fps on a low persistence display gives you obvious flicker. It would be better to standardize on 120fps (as with Billy Lynn's Long Halftime Walk), because that gives acceptable motion quality even on a sample-and-hold display, and it's an integer multiple of common frame rates so it's backwards compatible with legacy equipment with minimum quality loss.
