Is there a theory that says the universe has a limited 'processing power'?

If the universe is viewed to work in a similar way as a computer, wouldn't it have a maximum number of events that it could process at once? For example, could time possibly exist because the universe is 'lagging' because it cannot handle all of the reactions occurring throughout it in the past, present and future simultaneously?

There is a maximum processing power theoretically possible,  yes. It's called Bremermann's limit, and it's about 10^50 bits per second per kilogram of matter.

But your second question doesn't really make sense. The concepts of "at once", "simultaneously", and processing power all assume the existence of time, so time can't exist *because* of them.
