and 40fps feels like it’s a lot closer to 60fps than it really is.

Counter-intuitively, 40fps, not 45fps, is the mid point between 30fps and 60fps, so it really is closer than what a lot of people think.

On the surface that seems impossible, but looking at frame times tells the story.

Let’s divide 1 second by 30, 40, and 60:

• 1 / 30 = 0.033s per frame

• 1 / 40 = 0.025s per frame (0.08s less time per frame than 30fps)

• 1 / 60 = 0.017s per frame (0.08s less time per frame than 40fps)
