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.
Is this the highest it’s ever been? Pretty nuts.
I’d be curious to know that too but I can’t find any info on it. I mean it must surely be a contender because other huge releases typically have preload.
