Additionally, 37 games are getting FPS Boost mode today. If you’re unclear on what this means, FPS Boost is simply a feature that employs a variety of methods that nearly double the original framerate on select titles. This results in higher, steadier framerates to make games visually smoother. To see if the game you’re playing is running FPS Boost or Auto HDR, you can 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. The following games recieve an FPS boost today:
