It could still theoretically be that our reality is some kind of entertainment. For example, people enjoy playing The Sims. There are still active communities for the older versions even though there are newer, more engaging games out there. And more generally, some people prefer old games even though their computers have like 1000x the processing power needed to run it.
If the reality we experience is a simulation, it could be for similar motivations, the hardware would be sophisticated but still a user will run whatever they prefer on it.
