Answer 1

Older game engines may not have the concept of multithreading, or using multiple CPU cores at once. Games that can utilize multiple cores will often load faster and run faster than games that can only use one, because they can execute code faster. As far as I’m aware, multithreading didn’t work its way into most video game engines until 2010, or a little before.
