Xbox FPS Boost allows select backward-compatible Xbox games to run at double or even quadruple the original framerate without any developer input. So games you remember running at 30fps can now hit the heady heights of 60fps or even 120fps to make for an even better experience.
This feature is only available on Xbox Series X and Xbox Series S, so if you're still using a last-gen console, we've got bad news, just because it requires the vastly increased CPU power of these newer platforms to run the games at a higher framerate.
We've assembled the complete list of titles applicable to this feature and details on what framerate the games used to run at, how they run now, and any other particulars worth noting. It's worth noting that some Xbox FPS Boost games are considered some of the best Xbox Game Pass games, so it's worth taking a look.

List of Xbox FPS Boost games
Xbox FPS Boost doesn't require any developer input but it is subject to certain restrictions. Some games might only be patched on one platform since a backward compatible Xbox One X version could already be running a game at 60fps. Other games might be very demanding and require the settings to drop down to the Xbox One or Xbox One S version of a game before increasing the framerate.
Just be aware that Microsoft has now finished updating older games through FPS Boost, so don't expect any further additions to this list. Still, if you've ever wanted to revisit a game but couldn't bear to play it at 30fps, then, check out the full list of FPS Boost-supported games below.
How do I use Xbox FPS Boost?
In order to take advantage of this framerate-boosting feature, you'll just need to play the games on your Xbox Series X or Xbox Series S. It'll automatically be enabled as long as your console has the latest updates.
To verify a game is running with FPS Boost, you can press the Xbox button on your controller to check for the FPS Boost and/or Auto HDR labels. Some games have FPS Boost turned off by default, but it can be easily turned on under the Compatibility Options in the Manage game and add-ons setting.
Do note that in order to enjoy a game at 120 FPS on Xbox Series X or S, you'll want to make sure you have one of the best 120Hz TVs available. You'll also need to enable 120Hz on Xbox Series X and Xbox Series S.
