This YouTuber hacked SteamOS onto a ROG Ally handheld

">a popular SteamOS derivative that can do this to some extent already. This is unmodified SteamOS code, hot out of Valve’s open-source oven.

That being the case, there are still a lot of issues. It’s technically up and running on the Ally—which uses an AMD chip that’s different-but-similar to the Steam Deck’s Ryzen APU—but runs into problems and anomalies arising from its faster, higher-res screen, lack of touchpads, slightly different control layout, etc.

The Phawx says that SteamOS recognizes the Ally’s input as an “Atari Xbox 360” controller, presumably using some generic driver. The back keys aren’t working quite right, ditto for some of the extra control buttons. SteamOS recognizes the 120Hz refresh rate on the screen as well as its VRR capability, but the TDP setting (which is also fairly similar to the Steam Deck) is locked at 15 watts, which means it’ll burn through far more battery than it should on low-power 2D games.

But despite these problems, the performance for most games is about where you’d expect. Older and lower-power games work great, easily hitting 120Hz, though some newer games like Cyberpunk 2077 are obviously struggling with a lack of optimization. The Ally with its more powerful Ryzen Z1 Extreme APU seems to have measurably more power than the equivalent Steam Deck, though perhaps not with a performance delta that you might hope for on the same OS.

Overall, it’s a promising preview of how SteamOS is going to perform on non-Steam Deck devices, especially considering that the release version for the Legion Go S should end up being a lot more polished. Since Valve is working directly with Lenovo here, I’d expect to see even better results, especially with the more expensive Z1 Extreme version of that handheld. It’s scheduled to go on sale in May, though we still don’t have confirmation of when (or if) a SteamOS build will be available for Asus’ gaming handhelds.
