Some games, like Metroid Prime 3, have lag issues when Enable Speaker Data is enabled on some systems. Hi I just received my very first PC today, and one of the first things I wanted to do was play some emulated games. If you need help, or want game-specific configurations, see the forums. This has great use for Hotkey and Tool-Assisted Speedrun users, and it is required for Free Look (if enabled under Utility section in Options > Graphics Settings > 'Advanced' tab) and a way to exit Fullscreen.
