Train Sim World 2 operates with an unlocked framerate, which means it runs as well as the hardware allows it. If you connect a keyboard to your console then it's possible to display a framerate counter in the top right corner (I don't know the exact shortcut, though). The base Xbox One runs the game mostly around 25-30 fps but it's not constant. Xbox One X around 25-40 fps at 1080p and somewhat lower at 4K. The Xbox Series X|S consoles run it at an almost stable 60 fps with occasional dips.
