The local caching works in the background.

After saving a project, you can continue to work on the project while it is synchronizing your changes with the server. When you save the project, it synchronizes the changes, similar to the check-in process. While working on a checked-out project, you may want to occasionally save the project to Project Server without checking it back in. When you check the project back in to Project Server, only those changes that were made while the project was checked out are synchronized to the server version of the project. As you make changes to the checked-out project, those changes are saved to the local version of the project. When you check out a project, the local version is updated with changes made to the server version. The local cache helps you work more efficiently by synchronizing a local version of your project with the version stored on Project Server.

You can adjust the cache size and location, and select specific projects to remove from the cache. Project uses a local cache to let you work with projects as if they were stored locally, making the Save and Open operations much faster than in previous versions.
