You probably know this 100ms = 10 FPS. What kind of display shows video at less than 10fps? Game engines aren't always synced to frame rates, particularly simulations. But a simulation that updates every 0.1s isn't great for fidelity.

A 30 fps game could go through a complete loop, updating everything: object positions, inputs in 33ms. At 60 fps assuming everything is synced to frame rate that would 16 ms.

I was asking for the commenter's source of information so I didn't have to guess what he or she meant. It's possible to make a game that doesn't respond a user's input in less than 200ms, but why would you? You don't need to be making a technical tour de force to respond in 16-33ms.
