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.
And it still gave me 800Mbps consistently right at launch time. Good servers.
Steam has some of the most consistent and high quality servers around. It’s quite rare to see them slow down or go down, at least in my experience.
And at best only during specific sales like the Steam deck their servers became unresponsive for a bit.
I wonder how much they paid for that launch bandwith.
