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.
Exactly my case, downloaded yesterday so I can play all weekend. Don't have but an hour to play during the work week. Definitely not starting this game with just an hour.
Keep in mind that the game has been in Early Access for almost three years. Anybody who played the game in that span but hasn't launched it since yesterday is going to push that percentage down.
i think thats a display bug. if i hover over my own "descent from avernus" it also shows me .1%, however if i hover over one of my coop partners it shows as 40%
