I got 535 megabits per second out of a launch edition xbone after I wired my master bedroom with ethernet while downloading a system update. Games typically do 280-350 megabits per second for me. it might depend on what part of the country you live in. I live in AR ffs and saw almost double what you do once.The one problem with the Xbox and the Windows Games store is this: They cap the speed at which you can download games. The best I get is about 280Mbps on my Xbox One X or through the Windows XBox app and this is on a Gigabit Internet connection. And nope, the problem is not on my end, unfortunately.
