Windows Was The Problem All Along - Dave2D
We could obviously compare performance between windows and steamOS before on the steam deck, or between windows and Bazzite on other handhelds. But this is the first time we have had official windows and SteamOS builds for the same hardware.
Why? Isn’t SteamOS a stripped down version of Linux?
SteamOS is a full Linux build, it’s just a different distro like Fedora, Ubuntu, mint, etc, etc
Like a distro with certain bloat disabled to optimize for gaming?
SteamOS is purpose built for gaming. Windows LTSC is specifically not for gaming, but many shoehorn it into it.
