like Fallout 4 that has Dynamic resolution, better draw distance and god rays on the One X.
or Middle-Earth: Shadow of war that has dynamic resolution scaling, increased draw distances, better texture detail, better shadows and lighting, more vegetation.
Itll have all the One S enhancements, seems alot of ppl dont realize the One S actually did enhance games lol See below
Any enhancements the Xbox One S does, the Series S will also do, but a bit better, so lets say the One S boosted a dynamic res game to 1080p, but it would sometimes dip to 720p in intensive areas of the game, the series S will boost it to 1080p more consistently, an probably will be locked to 1080p in comparison, same with the framerate of games, if a game was dipping below 30 on One S, it'll probably locked to 30 on series s. Enhancements like that, the One X was boosting games to 4k though, thats really the only major difference.
