How to play PC Games on Xbox Series S

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?

But in all other write ups the game is listed as complete

I have several disc games for my Xbox One, i am buying a Series S, but how will i pay them on it?

You wouldnt. Xbox Series S can only play digital games so if you want to play them on Series S you would have to repurchase them digitally.

It's not possible to install on xbox one s only pc series s or x

Xbox one games are xbox one not s or x

.also should.be noted you can play msfs only in cloud on xbox one

To answer your question, you can stream any game in your library. However, as other's have already stated, this is purely a video feed from the console to your PC. None of your PC hardware will be used. Cyberpunk runs pretty bad on Xbox One hardware and it won't play any better by streaming it.

If Cyberpunk is the game you want to play then you'll ideally need a Series X or a Series S console. The Series S version has recently been given a 60fps patch. If you want to play it on a PC, you'll need a suitable gaming PC.
