A YouTuber claims that Windows was actively causing handhelds to run poorly, at least versus SteamOS
Windows? Causing performance issues? Say it ain't so.

As Valve rolls out official support for handheld consoles outside of the Steam Deck, we're seeing people compare Windows versus SteamOS performance on the same hardware. After all, if swapping operating systems scores you better framerates and less power drain, jumping ship for the performance gains alone would make a ton of sense.
