Microsoft revealed at its Gamescom press event today that the company has more than 100 games ready and enhanced for the upcoming Xbox One X console. The enhancements will include 4K and HDR support in many cases, and mean that a game has been updated to support the new power inside the Xbox One X. Sony had more than 45 games enhanced for the PS4 Pro during its launch period last year.

While game makers can’t create titles only for the Xbox One X, they can provide more assets, a higher resolution, and better frame rates on the console. All of these optimizations fall under a new “Xbox One X Enhanced” program. The optimizations might not always be clear, but Microsoft is using three logos in total for new Xbox One games. There’s an enhanced logo to indicate a game has been updated for the Xbox One X, and a 4K and HDR logo to note specific support.
