Xbox Series X tags in the new Microsoft store appear for games that will be optimised for...

Hi,

Series X|S optimised games can only run on either the internal storage or expansion card. You can 'store' Series X|S on a USB hard drive/SSD for later but you can't play them from these drives as they're not fast enough.

Xbox One games that are not optimised for Series X|S can be run from USB Storage.

Hi

Forza Horizon 4 is now an Series X|S Optimised Xbox One game. Optimised games can only be run from either internal storage or the optional expansion card. If you move an Optimised or Series X|S game to an external hard drive it can no longer run from this type of drive, it can only be stored there. That's what the two apposing arrows represent.

Hi,

Both Series X/S games and Xbox One games that been optimised (I'm British) for Series X/S must be installed on either the internal storage or the expansion card. They can not be run from a USB connected storage device. My optimised Series X/S Xbox One games
were moved to my Expansion card during their update.

Hi,

Red Dead Redemption 2 on Xbox was only optimised for Xbox One X it hasn't been optimised for the Series S or X hardware. On the Series S it runs in Xbox One Backwards compatibility mode. As such, it runs at around 900P (around 1600x900). This means it will look quite soft looking on a 4K display, although it should not affect the colours or the contrast.

Unfortunately, RDR2 is not great on the Series S, especially on a 4K display. FIFA 23 is Series S|X optimised, which is why this game looks a lot better.

Yeah I understand this, but like I said before...all the games are in the external, but for whatever reason is upgrading and updating to the internal.

This behaviour only occurs on Series X|S optimised games and only on the series X|S console.

Basically, if you have an Series X and your Xbox One game has been optimised for the system it will be moved to the faster storage during the update.
