Smooth loading of non-preloaded assets

If we have a project where nothing is preloaded, there will be a long period when first starting the app where it freezes and stutters. It's not a pleasant experience for the user who thinks the application has loaded, but can't interact with it.

Try running this scene, and move the camera. I'm measuring around 5-10 seconds of freezing and stuttering after the application has loaded. Also, if you let the application load for a while, then move the camera around, you'll get stutters and freezing when new objects come into view. This is a quite small application, just imagine a large game world having this issue.

Is there a way to smooth out these loading times?

Start by running the linked scene and profiling startup plus camera movement as new objects enter view. Compare the freeze and stutter during initial and visibility-triggered asset loading, then identify a feasible way to smooth those loading periods. Done means the scene remains responsive while non-preloaded assets load.
