Is it just downloading it? (Ps4 per fortnite)?

See image. Never had a ps4. Now want to switch from Nintendo Switch to ps4 and know me can't stand it.

Jo does it, but looks like it's about 2%

Yes, loads (although I would not recommend Fortnite)

Yes, it loads, but it will take even longer to load. This is what you see in this bar under the name of the game.
