One thing you won’t be doing when you play the beta is doing it at 60 frames per second. This is because while that is technically possible, the team decided to cap it at 30 fps as a trade-off. “Could we make a Destiny game that ran at 60 fps?” Bungie said in Edge magazine this month. “Yes, but the space would be smaller, it would be less cooperative, and there’d be fewer monsters to shoot. That’s not the game we want to make.”
