Microsoft Corp. this month confirmed the Xbox Series X hardware will be backwards compatible with thousands of Xbox games at launch.

The company said it has spent more than 100,000 hours testing game titles from the Xbox One, Xbox 360, and the Xbox.

The Xbox Series X is said to include performance twice that of the Xbox One X and eight times that of the Xbox One.

As a result, the hardware will support up to 120 frames-per-second graphics fidelity.

A new feature called Smart Delivery will optimize performance of prior generation titles from Xbox to the Xbox One for the Xbox Series X.

Dynamic Latency Input will allow input synchronization for more precise and responsive controls.

Finally, Quick Resume will allow users to continue multiple games from a suspended state without long load times.

Graphics fidelity includes 4K at 60FPS, Variable Refresh Rate, Variable Rate Shading, 8K functionality. The hardware itself can be placed in vertical or horizontal orientation.

Final specifications include a next-generation SSD, Auto Low Latency Mode, and Dynamic Latency Input to limit latency.

In addition, the Xbox Wireless Controller has been refined to include a new Share button and an advanced d-pad from the Xbox Elite Series 2 Wireless Controller. It will be compatible with Xbox One and Windows PCs.
