> The 60 fps mark isn't really latency related. Instead, at 60 fps animation without motion blur feels smooth. At 30 fps you need motion blur or it feels like it stutters (and in 24hz cinema the camera produces natural motion blur due to shutter time).

Really, this is related to the speed of motion. If everything is moving slowly, 30 fps is fine; if something is moving quickly enough, even 60 fps looks choppy. Try scrolling a long page really fast on your smartphone, for example.
