From The Verge: "If you’ve noticed some issues with Fortnite on Xbox One today then Kinect could be to blame. Epic Games is encouraging Fortnite players to disconnect their Kinect camera due to “stability issues” when starting up Fortnite. The issues appear to have started happening today, just as the 10th season of Fortnite, dubbed season X, began. “We’re investigating a fix for this issue, but players can work around it in the meantime by disconnecting their Kinect,” says Epic Games on Twitter.
It’s not clear why Kinect is causing Fortnite issues, especially as it has been five years since Microsoft stopped reserving GPU resources for Kinect. Microsoft used to reserve 10 percent of GPU bandwidth for Kinect, before unlocking this for developers to use as they wish."
