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.
A lot of older games were bigger because of static assets. Riven (myst 2) was fucking huge because it was like 60,000 jpgs. It was on 5 discs. Later games running in a 3D engine just had texture files and small models, they were a lot smaller.
There’s that quake 2 clone that team did a while back that was only 92KB- it generated everything in memory on the fly. Krieger I think it was called?
