At Xbox, we're all about giving you the choice in how you want to play your favorite games, whether in its original form or with FPS Boost and/or Auto HDR. As we also detailed a few weeks back and included as part of our March Platform Update, you can now go into the "Manage Game" section for any enhanced title, where you'll see the new "Compatibility Options" button that will allow you to toggle FPS Boost and Auto HDR "on" or "off."
To see if the game you're playing is running FPS Boost or Auto HDR, you can also now just tap the Xbox Button on your controller while in the game and you'll see a Guide overlay indicator in the upper right corner if the features are enabled or not. To experience FPS Boost for these iconic Bethesda titles, and to be able to toggle the feature on and off, make sure your console has taken the latest update and you've rebooted your console. After that, you're good to go.
