From Steam’s self-published stats.
Baldur’s Gate 3 could not be preloaded and weighed in at 125 gigabytes on disk, so when the game left Early Access at 11am US Eastern yesterday, Steam’s bandwidth utilization shot up 8x over a span of 30 minutes. I know personally, I saw my download hit over 600 Mbps across a 1 Gbps fiber connection.
Kudos to the system engineers at Valve. It is mind-boggling that they have built infrastructure that robust.
Off the top of my head, I know Windows Update and the Battle.net launcher both do this
And on Windows it’s so poorly implemented they had to reserve 20% of bandwidth for updates being uploaded and downloaded and you don’t get a choice on that. So when Windows is sharing its updates your internet access suffers.
Jokes on windows, my WiFi is just funky enough that transfers between devices on LAN run like dogshit so it gives up before it even starts!
…I really need to invest the time into finding & implementing a better network solution
Do you have any source or article about this? I’d love to hear more about this.
Microsoft’s implementation of the feature is called Windows Update Delivery Optimization.
Here’s a short optimisation guide: https://www.ctrl.blog/entry/windows-delivery-optimization.html
Fundamentally it’s not like the Bittorrent protocol, even though there are similar behaviours and the result is the same. Microsoft retains the ability to stop the network from seeding updates and has ways of only targeting specific supported configurations to receive new updates.
