is to have all threads know how to sync with whichever other thread they need to sync with, whenever they need to. This way tends to be more difficult (and I am yet to think of a use case and application methodology for this method).

Now usually you make sure not to have any blocking function (large calculation or file R/W requiring HDD fetching) on the main thread. Maybe they made some mistakes in this regard in their previous games and did better this time.

From what I see, it seems like they didn't use the graphics API (seems to be Vulkan) properly enough, for which I can't do anything, given my lack of exp with it. Perhaps a god time for me to delve into Vulkan.
