FPS Boost is a clever technology that doubles, even quadruples the frame rate of existing Xbox One games for play on the Xbox Series X/S. It is applied at system level by the Xbox itself, so doesn't require a developer to change or remaster its game. This is different to some publisher rereleases or games "optimised for Xbox Series X/S". It is also only applicable on certain games announced as compatible. Most of the titles announced so far are now capable of running at a locked 60 frames per second - while they were originally locked at 30fps. One, New Super Lucky's Tale, even gets a boost up to 120fps. You will need a TV capable of 60Hz or 120Hz respectively, but you won't have to do anything in the settings of your Xbox to benefit. A game running with FPS Boost enabled will get a pop-up on screen as you start it - much like you do when Auto HDR or Quick Resume is enabled. From the spring, you will be able to manually switch FPS Boost (and Auto HDR) on or off in new compatibility options on the game management screen.
