Xbox Series X will be backwards compatible with "thousands of games" at launch

By Sean Carey,
The Xbox Series X will not only be backwards compatible with thousands of games at launch, but some will also perform better by making use of the next-gen console's hardware. The new Quick Resume feature will also work with backwards compatible titles, and the Series X can automatically add HDR support to older games including Xbox 360, and original Xbox titles with zero impact to performance.

Xbox Series X backwards comptability

A post over on Xbox Wire from the director of program management for Xbox Series X, Jason Ronald, says, that more than "100,000 hours of playtesting has already been completed" and "thousands of games are already playable on Xbox Series X today". This includes some of the "biggest games and cult classics". Ronald continues, "Many of us in Team Xbox play on the Xbox Series X daily as our primary console and switching between generations is seamless."

Backwards compatible games will run natively on the Xbox Series X hardware making full use of the new CPU, GPU and SSD. There is no boost mode or downclocking, meaning that each backwards compatible title will use the full power of the Xbox Series X. Because of this, some games will see a performance boost with higher and more reliable frame rates. Ronald says, "The compatibility team has invented brand new techniques that enable even more titles to run at higher resolutions and image quality. We are also creating whole new classes of innovations including the ability to double the frame rate of a select set of titles from 30 fps to 60 fps or 60 fps to 120 fps." Games will also be rendered at the maximum resolution and will see a reduction in load times thanks to the new NVME SSD.

The Xbox Series X will also deliver a new "HDR reconstruction technique" that will automatically add HDR support to older games, including Xbox 360 and original Xbox titles. The technique is "handled by the platform itself" and adds HDR with zero impact to the game's performance.

The new Quick Resume feature for the Series X will also work with backwards compatible titles, and allows the player to pick up where they left off across several different games.

We expect to hear more on the Xbox Series X and backwards compatibility in the run-up to the launch of the console this Holiday.
