Microsoft highlighted all the way back in May that it was working on "new classes of innovations including the ability to double the frame rate of a select set of titles" with backwards compatibility on Xbox Series X|S, and it has now confirmed that the first of those games is Bethesda's Fallout 4.

As you can see in the video above, the game now runs at 60fps on both the Xbox Series X and Xbox Series S, which is a big improvement over the 30fps max frame rate on the Xbox One X version.

"While not applicable for many titles due to the game’s original physics or animations, these new techniques the team has developed 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. Fallout 4 framerate is effectively doubled from 30fps to 60fps on Xbox Series S, delivering a new way to preserve and enjoy this legendary title."

This will only apply to select games, of course, but the vast majority of backwards compatible titles will also take advantage of Auto HDR, 16x anisotropic filtering and significantly faster load times, and early previews have noted how some back compat games run considerably better on the Xbox Series X without any optimisation as well.
