60 and 120 are worlds apart, especially in VR. I would be shocked if many people with healthy mind and vision couldn't see the difference after having the basic idea explained to them. In VR some people might even physically feel the difference. Doubtless there is some refresh rate where it ceases to matter, but the point here is that we're still struggling to push an acceptable frame rate in VR (and 4k, and other high resolution "formats") without making significant sacrifices in other aspects of the video quality. Assuming that image quality and available processing power both continue to increase, it will continue to be important to include framerate in the balance, i.e. we want to draw enough but not be wasteful.
