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.
And why would they? They’re printing so much money, this niche probably doesn’t make a dent.
It doesn’t matter if Windows is the best system for gaming. It just matters if people believe it is.
You can always justify using Windows. “How do I get Game Pass to work on my handheld?” is probably something people care about.
Granted this is an expensive way to lock customers into your platform, but they’re already doing it anyways, so no need to pour money into the OS experience when you can just sell services building on customer data.
