I bought the Ultimate Digital edition yesterday to make sure I can start playing as fast as possible. Now 12 hours later I am still at "Installing… 2%) When I look at the bandwidth usage it’s barely using any network. I trying installing another game, Tomb Raider for instance and I was downloading it at 122 Mbps and it did the installation in about 5 minutes. The issue is clearly on Turn10 side. I did contact Microsoft support but after we cleared out that the issue is not on my side or my ISP (Bell Canada 1 Gbps) they told me they couldn’t do more and suggested contacting the game developer.
You are not alone… I bought the game on the 18th and when I got up on the 19th, after over 10 hours downloading, it was still at 62%. So I waited a couple of hours and it was still at 62% so I took my console to work, as they have a 100Mb connection, and installed it there… and it still took over 5 hours.
So yep I would guess server bandwidth is being limited.
Do NOT interrupt the download, and don’t do other things on the console as it is downloading or installing. Wait until it has finished 100% before attempt to play, too.
Any other activities on the console will suspend/delay any downloads because the Xbox One attempts to assign priorities to activities, i.e., live gaming is more important than a download.
