As spotted by reports from RespawnFirst and testing shared on X by user @girlglock_, the updated Steam client now completes a cold boot in just 5.23 seconds on comparable test hardware. That shaves nearly five seconds off the previous figure Epic used in its comparison charts, and edges past the 5.47-second benchmark set by Epic’s new AI-assisted preview build.
They both still start too slowly, 5s to open an application on SSD is slow.
Steam has been working on start up time for a while now, in September they started updating it for the Seam Machine and Big Picture mode, but the whole thing got faster. I'm pretty sure this has been in the beta client for a month, so it seems stupid that Epic would go with such a strong marketing push about how slow steam is on something steam is actively improving.
My best guess is they thought they could put this out while technically true and look good, and nobody would notice when Steam shipped this? Just weird marketing.
