Quote: “We are aware of performance issues in a handful of optimized titles on Xbox Series X|S and are actively working with our partners to identify and resolve the issues to ensure an optimal experience,” says a Microsoft spokesperson in a statement to The Verge. “As we begin a new console generation, our partners are just now scratching the surface of what next-gen consoles can do and minor bug fixes are expected as they learn how to take full advantage of our new platform. We are eager to continue working with developers to further explore the capability of Xbox Series X|S in the future.”
So MS doesn't confirm or deny any cause for the issues, it just acknowledge there is one and that it will improve with time and devs leaning more about how to develop for the system.
