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.
Probably this. Especially on low end hardware that doesn’t really have a lot of background resources to give.
Just open task manager and see all the shit windows thinks is essential to run all the time. Scanning the drive for viruses, downloading updates for shit you’ve never even looked at…
