For the users: One good trick is to open Task Manager and look at how much memory the game exe is using. This value will slowly increase as the game loading progresses, and then you'll see the game window appear.- Initial load times are long, on some laptops.
This happens right after the Unity splash screen and before the "Profile manangement" screen.
It looks like it hangs, but given time (up to three minutes on the laptop I tested it on), it will kick into action.
Once inside the game should run smoothly.
If you see two or more entries for the game exe in task manager, see which one's memory usage is increasing and kill the others, or just kill them all and relaunch the game.
