A spokesperson for Microsoft products confirmed that Xbox series s, the budget version of the new generation of consoles, does not support backward compatible titles of Xbox One X. Xbox Series S only supports Xbox One S and Xbox 360 video games, with HDR, shorter loading times, and a more consistent framerate.
Xbox Series S was designed to be the cheapest next-generation console and run next-generation video games at 1440P at 60fps. To deliver the highest quality experience compatible with backwards compatible versions in line with the developer's original intent, Xbox Series S runs the Xbox One S version of legacy compatible titles by applying an improved texture filter, higher frame rates. higher and more consistent, faster load times and automatic HDR.
Digital Foundry has taken for granted that Xbox S Series, having less RAM than Xbox Series X, does not support the same functions as One X: “Xbox One X has 9GB of system memory available for titles. Series S has 8 and I've read some reports that point out 7.5GB. In any case, it is less and less than Xbox One X, so it was practically assumed that backwards compatibility veered towards the Xbox One S versions, rather than Xbox One X ».
