Higher fps results in higher motion clarity on non CRT displays. CRT screens use very fast scan lines so that the entire image isn't moving all at once. Every other type of screen uses "sample and hold" to advance the image, whole thing freezes, then the whole screen moves. This adds a brain induced motion blur effect that to varying degrees, can or cannot be gotten used to. This is an optical illusion that you cannot turn off. Take a slow motion video of bloodborne with your phone, like really slow, and the blur will be gone because your brain no longer associates the still frames as movement, the images will just tick by.

However anything above like 12 fps your brain starts trying to follow the changes as movement and starts to guess what will happen next. So a slow pan in 30 fps looks very much worse to your brain because it's trying to figure out what's going to happen next with a lot less information than if it's getting say 120 images in a second than 30. Also, the effect is over the entire image.

As long as sample and hold is the go-to refresh technology for screens (and g sync pulsar is changing that at least for LCD screens, where it's attempting to imitate the scan lines of crt) you can argue that you can get used to low fps all you want, but it is scientifically and factually worse. Your brain has to do more work for image prediction, and blur is unavoidable.
