Are Xbox Series X|S optimized games even slightly enhanced for the Xbox One X?

Thanks. I know what you are meaning, but that's the list of the optimized games for this Series X/S gen. The Orange Box is a 360 game, optimized for Xbox One X (Xbox One X Enhanced), so backwards compatible, a game from previous generation (X360) playable on the Xone and also on the actual generation of console, thanks to the BC program of Microsoft. The game is not optimized for Series X/S, it would have to X/S logo like other games i own (Subnautica, We happy few etc). The only problem with this game is with the purchase from the Marketplace!

I would presume that if a game is Xbox One X Enhanced, those benefits will also appear when the game is played on Xbox Series X, along with any Optimized for Xbox Series X benefits that same game might receive through future updates. I doubt seriously it
would be a step backward when played on the superior hardware.

Keep in mind the Smart Delivery feature, which will enable Xbox Live to send the best possible version of the game to Xbox Series X automatically. So that may be the Xbox One X Enhanced version, or (if the developer makes such an update possible) the Optimized
for Xbox Series X version. Given the choice, I'd want the Optimized version.

Because on my Xbox series x, it only shows 'Optimized for series x/s' but if a xbox series x version of a game is NOT 'optimized' how would i know if I'm playing a series x/s version of a game?

HI,

This an Xbox One X enhanced game. But to get the enhancement you'll need either a Xbox One X or either one of the newer Series X|S machines. The Series S is a digital only console though.

On an original Xbox One or One S, it will be the BC 360 game with no enhanced graphics.

You'll get access to an enhanced version regardless of disc or digital, but you need the right console to be able play the enhanced version.

Xbox one isn't xbox one s or x compatible they are all compatible it's only the x that has some enhancements but generally the game will download on any xbox one

Series x is just xbox series s or x

Not xbox one s
