I think console players are catching up on the massive difference between 30 FPS and 60+ FPS in first person games where the camera can move quickly. As TVs have improved along with the consoles, and some titles are able to be played at 60+ FPS, people are noticing the difference compared to newer titles that aim for 30 FPS as a trade off for detailed graphics and motion blur.

Plus performance mode reduces the number of times a game might stutter or have short periods of time where the frames have a massive drop compared to their normal rate.
