Series X enhanced games installing twice

This is an incorrect assumption. You can insert an xbox one disc and download updates that may improve visuals and frame rates on Xbox Series X/S but in order to play you still need the disc unless you own the digital version of it.

Xbox Series X will utilize the Xbox One X version of enhancements while Xbox series S will use the Xbox One S enhancements.

You will not get a free game by borrowing or renting a physical version of a game and installing it on Xbox Series X/S.

Hi,

Your drive will work the same on Series X as it does on Xbox One and you won't need to format it.

However, Series X games or Xbox One games with Series X enhancements will not run from that drive and will either need to be installed internally or to an external SSD designed for Series X/S.

Your hard drive will be too slow for Series X games. They can be stored there, but not run from there.

Microsoft introduces "Smart Delivery" with the Xbox Series X, which means, that if you own an existing game (like Minecraft in your example, or Gears 5) or a new game comes out for Xbox One and Xbox Series X with improved graphics on Series X, you won't
have to buy the game twice.

With Smart Delivery you will play the "enhanced" version on Series X, and the "normal" version on Xbox One.

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.

I know that Series S can't use the XIX enhancements. I'm asking if the Series X
will be using the XIX Enhancements. Thank you for taking the time to respond however.

Yes, why wouldn't it be? Faster processor, graphics and more RAM (16 GB). I did already state in my previous reply that Series X will play X1X enhanced titles.

Digital Foundry (a popular YouTube tech channel) have shown a video of Gears 5 running on Series X.

Not only was Series X running the X1X Gears game, the developer has enhanced it again for Series X.
