Was going to echo this. From all of the flights I can recall I don’t think I ever actually ‘saw people’. You’re moving so quickly and are focusing on certain things as you pass by that people don’t register. If there would be anything like how they are depicted from GSX or airports, I’ll pass.
Also to add a side blurb, people having as many performance issues across the board as they are and yet we’re still asking to add things that would affect performance. Smart thing to do would to be eliminate issues and work on performance until everyone has 30 FPS minimum across the board and THEN talk about adding wishlists or features.
