120 FPS support is still limited on Xbox Series X|S, and it does come with some caveats like downgraded resolution, lesser visual fidelity, 120 FPS being restricted to certain modes, differences between Xbox Series X and S, and specific hardware requirements like a high-end TV with HDMI 2.0 or 2.1. Still, 120 FPS support in console gaming is, well, a game-changer for a lot of players who seek the fastest performance they can.
