Depends on the genre, input method (gamepad or mouse) and art style.
Many games are okay in locked 30 fps, even if I can see the difference to 60 fps. Some fast games on PC I play on my 120hz-display, because even 17 ms (60hz/fps) feel too unresponsive.
What I absolutely hate are 30fps-games with slowdowns to 20 - 25 fps.
