I really appreciate you trying to help but I hate to say it but you are wrong and that would not be a valid answer for my solution I am trying to achieve. If you are referring to the flip book to play out like a video would at lets say a constant frame rate like 30fps, then unfortunately that would be a very inefficient way of doing things and I can almost guarantee that no ones does that simply due to the added processing of not using a video codec along with any additional compression you would be foregoing not too mention the additional cost in memory and storage space on a per frame basis. Also, to sync up the frames would be a nightmare to ensure they are delivered at a constant rate. Now, if you wanted to do something akin to Metal Gear Solid: Ground Zeros where you have a loading screen and can advance, their case pages of text but that’s not what I am trying to achieve.
The way it works is that most games nowadays are multi-threaded. You could lets say have your Rendering Thread execute in parallel to the thread that is responsible for File I/O which would in turn allow you to continue to run while loading doesn’t have any effect or in the case that they describe in the release notes, “make your screen hang”. Because they said that it is there to alleviate “Blocking Loads” gives me the impression that it is exactly what I am looking for and not specific to just Persistent Levels. I’ll have to wait to see what they say on that one or test it myself once I get past a couple bugs.
Also, in most games, they play a movie while loading is executing. A couple great examples of this are the Mass Effect 2 or 3 and Halo 4 loading screens. This stated as documented for Xbox One but I am also curious if this is easily achieved at the moment on PCs.
