Short Question

If my application is already rendering at 60fps, is there any additional benefit (from perspective of human perception) to render additional frames on state changes?

Long question

I’m writing an interactive application in OpenGL, something like:

while(true) {
  render a frame;
  sleep right amount of time to hit 60fps
}

Now, in the MVC model, I would fire off a repaint on every state changes.

My question:

Given that I’m already rendering at 60fps from the model, is there any benefit to fire off a new repaint at every state change? Can humans actually perceive the slight difference in 33 milliseconds?

    Yes they can, especially elite FPS gamers. You could set up a fixed time step system or some similar system to render as fast as possible and use interpolation during your extra frames to smooth animation. This can definitely make a difference, but then again time-resources-cost, maybe you have no need to have super smooth rendering.
