FPS in Level Sequence

What does the FPS in the Level Sequence actually mean.

  • Will actually play back ONLY at that FPS on a device?
  • If we set it to 5FPS would the animation actually only update every 5 frames?
  • If we have it set to 30fps would it look slightly out of sync on a device playing at 180fps?
  • If we want it smooth all the time should it be set to 240 all the time?
  • Are there issues with setting it high, such as performance?
  • What happens when the device can’t play at that fast of a fps?
  • Is the FPS setting only for picking a setting to assist in animation timing? and doesn’t actually affect playback? (I think this might be the answer, but I’m not sure)
