In a not-so-scientific benchmark conducted by YouTuber Cyber Dopamine, the Rog Xbox Ally managed to perform better without Windows, the operating system it ships with out of the box. Cyber installed Bazzite, a popular Linux distro for handhelds built specifically to offer that console-esque, seamless experience. Visually, Bazzite looks identical to SteamOS because it uses Steam’s Big Picture Mode as its main launcher. It also behaves similarly, but has its own custom menus and settings for customizing things like power profiles (which override Asus’ built-in ones).
When testing Kingdom Come: Deliverance 2, Cyber noticed a shockingly significant jump in FPS, with Linux generating ~32% more FPS compared to Windows. This trend follows at lower wattages, albeit with less noticeable differences, and the delta actually plateaus in Hogwarts Legacy to the point that both Bazzite and the Xbox FSE offer the same FPS at 13W. That being said, those frame rates are much more consistent on Linux, according to Cyber, who shows that the FPS graph on Windows fluctuates regularly, while staying mostly flat on Bazzite.
Pretty hilarious if after years of being the scourge of Linux and FOSS advocates, complaining how they could never leave Windows because they need it to play, gamers become our greatest allies, switching in droves to get more out of their hardware and games.
Really, this isn’t entirely new, I remember some games were known to run better on Wine than Windows years ago already (Soldier of Fortune comes to mind).
