So could u still play a game on a old gen if it says optimized for Xbox series x/s

You would have to check if the game was released on older gen or not. If it says it's only for Series S/X, then no. If it says it'll work on both the One and Series S/X, then yes.

A game can be optimized for the Series S/X but still work on both, but not always.

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?

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!

Keep in mind you need a series x or s to play ir

Xbox one's arent compatible since they are over 10 years old and this include xbox one x

When xbox one games are made thwy just say xbox one not s or x

However for next gen games it's series s or x or both for digital releases only

Hi CarGuyB3N.

Cyberpunk 2077 will download the Series X updated version free via. Smart Delivery, but
note that COD: Cold War will not if you have the Standard Edition, but you will still be able to play it without the Series X upgrade. You either have to buy a digital upgrade or purchase the Cross-Gen or Ultimate edition of the disc release,
to be able to access the Series X upgrade download.
