With more than 600 games from previous generations working on Xbox One, as well as the massive library of games released for Xbox One available, the Xbox Series X will have thousands of compatible games at launch. This feat required Microsoft to clear major hurdles when it comes to system and chip architecture to allow games from multiple generations to be played on the newest hardware. In addition, Microsoft has put in more than 100,000 hours of playtesting to make sure that Series X is not only compatible with your current libraries, but also delivering an optimal performance in ways past systems couldn’t.
According to Xbox, all backwards compatible games run natively on Xbox Series X hardware, utilizing the full power of the CPU, GPU, and SSD. This enables older games to achieve performance that is at least what was delivered on the game’s original system, while sometimes performing in ways that were impossible on lesser hardware. Some backwards compatible games running on Xbox Series X could see improvements in higher and more steady framerates, higher maximum resolution, better visual quality, and shorter load times. Xbox Series X also uses new technology to automatically add HDR support to games with no impact to that game’s performance. Additionally, the new Quick Resume feature of Xbox Series X, which allows you to jump right back in to a game where you left off across multiple titles, works with backwards compatible games as well.
On top of that, Xbox is working on methods to deliver new innovations to a small list of older games to update them to modern standards of image quality, resolution, and performance while still respecting the original artistic intent. For example, a method the team is using allows them to update older games to 4K resolution, or even double framerates from 30 fps to 60 fps or from 60 fps to 120 fps.
Microsoft also mentions achievements, game progress, and friends lists carrying forward. We’ll continue to learn more about Xbox Series X, its capabilities, and its games in the coming months ahead of its holiday 2020 launch.
