The Xbox backwards compatibility team developed this function to employ a variety of techniques for nearly doubling frame rates on games, many of which will be available on Xbox Game Pass.
With the increased CPU, GPU and memory from the new Xbox Series X|S console, all of your existing games look and play better. With certain titles, we can make the experience even better, all with no work required by the developer, and no update needed by the gamer. To that end, the backward compatibility team has developed FPS Boost, which employs a variety of new methods for nearly doubling (and in a few instances, quadrupling) the original framerate on select titles. Higher, steadier framerates make games visually smoother, resulting in more immersive gameplay. We partnered closely with developers to enhance the experience while maintaining the game’s original intent.
And while not applicable to all games, these new techniques can push game engines to render more quickly for a buttery smooth experience beyond what the original game might have delivered due to the capabilities of the hardware at the time.
Today, Microsoft announced that over 70 titles, includes games such as DiRT 4, Wasteland 3 and Watch Dogs, are receiving updates to enable FPS Boost on Xbox Series X|S with support up to 120hz.
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.
This update brings the total titles boosted to 97; here's the full list to date:
In some instances, because there are higher graphics requirements to enable FPS Boost technology, we’ve had to reduce a game’s resolution to ensure it both runs smoothly and plays great. In those select cases, FPS Boost is not automatically enabled for Xbox Series X gamers, but can easily be turned on under the Compatibility Options in the Manage game and add-ons setting.
To experience FPS Boost 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.
Many of the games supporting FPS Boost are available in Xbox Game Pass and EA Play (included with an Xbox Game Pass Ultimate subscription). See the full list of Xbox Game Pass and EA Play games at the official website.
