ELI5: When the black loading screen of a video-game is happening, what is actually going on 'behind it'?
gpt
When you want to paint a picture you need all sorts of things. You need clean brushes, the right paints for the job and new clean pieces of paper. 


While the game is loading. It's clearing away anything it doesn't need and getting the graphics card ready to draw a new picture. It's cleaning off your paint brushes. It's also getting you a new clean section if memory to remember everything you're about to do. So clearing off the desk of old stuff and pulling out a new piece of paper. 


It's loading in the things you need from storage like a harddrive and putting it somewhere quick and convenient to access from like RAM. So pulling out your paints and pencils and reference sketches from a drawer and moving them to your desk.
