Wouldn't it feel like 10fps for 0.1s only? I agree it's a good thing to measure, I think it's called "stutter" usually, but I'm not sure you can say "it feels like 10 fps" since its for such a small moment.
Yes, you are right. The word I was looking for is smoothness: the game won't feel like a stable 10fps, but it would feel as _smooth_ as a 10fps game, or even worse actually, because it's less predictable, and our brains can adapt to stable latency relatively well
