Loding time faster on mobile then on gtx powered PC?

You should look into the puzzle dealing with turning on and off rendering.
Turn it off before anything.
Then when a variable saying all loaded is true, turn back on.

Desktops have higher resolutions to render the viewport on, so that can be exponentially larger rendering computation while loading occurs.

I think I’m partially correct on this.
Going to experiment with it now also.

To control the order of puzzles loading, put your puzzles in “procedure” puzzles then right click turn to get a small tag puzzle that is used to “call” them.. Then put only your main procedure that calls the others’ tag on the background. It will go first.

So you’d make your first procedure that’s called, from the main one, be stop rendering.

Kind of like the structure I have here (but this didn’t have rendering involved)…
