I haven’t noticed too much menu performance weirdness, but I do kinda agree that they’re weird.
They started it with Battlefront, and from a design standpoint I love them. They’re super modern and super clean and sexy, but they just don’t fit the spirit of the games. It feels a bit like Assassin’s Creed where you’re (spoilers?) playing a game set in a certain time period through a futuristic modern real-world interface, and that just rubs me wrong, gives it a kinda clinical “you’re playing a game” feel, and takes me out of it immersion-wise. I’d prefer if the menus fit the game.
