How much did Roman culture actually change following the beginnings of the imperial system?

It wasn't very different in the 2nd century AD from the 1st century BC. The Crisis of the Third Century is where things massively shifted. A Roman of the 2nd century meeting one from the late 4th would be very surprised. He would be a Christian, trouser wearing, hat wearing person.
At the very very start? Not much really.
