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.
makes a lot of sense honestly. I never knew the numbers behind it (tks for sharing). when I was ripping witcher 3 on nobara and then changed my OS back to Windows due to work related issues, I felt a SIGNIFICANT performance drop. the game became laggy, when it used to run top on Linux with the same settings. good share - the time for Linux gaming is now.
