Why SteamOS on the ROG Ally X Surpassed My Steam Deck Experience

As someone who jumped on the Steam Deck bandwagon early, I've always appreciated how SteamOS transformed my gaming habits—freeing me from my desk and offering a seamless, console-like interface for my PC library. But my love for the operating system led me to try it on other AMD-powered handhelds, only to be let down by missing features or poor performance. That all changed when I installed SteamOS on the ASUS ROG Ally X. Here’s my experience in Q&A form.

Why did you originally choose the Steam Deck over other handhelds?

I was an early adopter of the Steam Deck because it promised exactly what I wanted: a portable way to play my massive Steam library without the hassle of Windows. The tight integration between hardware and software made navigation fluid, and the quick resume feature was a game-changer. I loved being able to jump in and out of games instantly, and the trackpads offered precise control for strategy titles. At the time, no other handheld matched that polished experience, so I stuck with the Deck even as competitors launched.

Had you tried running SteamOS on other handhelds before the ROG Ally X?

Yes, several times. I experimented with installing SteamOS on other AMD-powered devices like the Aya Neo and OneXPlayer. Each attempt ended in disappointment. While the OS booted and games ran, critical features like audio output, sleep/wake states, or controller mapping either didn’t work properly or required manual tweaks that broke the intended plug-and-play experience. I always reverted to Windows, feeling that SteamOS wasn’t ready for non-Valve hardware.

What made the ROG Ally X different?

The ROG Ally X is built with better hardware integration and more compatible drivers. When I installed SteamOS on it, everything worked out of the box—audio, Wi-Fi, Bluetooth, and even the RGB lighting. The AMD Z1 Extreme chip is similar to the Deck’s custom APU, but with higher clock speeds and improved thermal management. This allowed SteamOS to leverage full hardware acceleration without any patches. The experience felt as native as on the Deck itself, but with noticeably faster load times and smoother frame rates.

How does SteamOS perform on the ROG Ally X versus the Steam Deck?

In my testing, games on the ROG Ally X ran at higher average FPS with less stuttering. For example, Cyberpunk 2077 hit 40–50 FPS on low settings, compared to 30–40 on the Deck. Even indie titles like Hades felt snappier. The battery life is also superior—the Ally X’s larger battery gives me about 2–3 extra hours of playtime. The only trade-off is the lack of trackpads, but I adapted using the thumbsticks and gyro aiming. Overall, SteamOS on the Ally X offers a more responsive and visually consistent experience.

Did you completely stop using your Steam Deck after this?

Yes. After a week of using SteamOS on the ROG Ally X, I packed away my Steam Deck and haven’t looked back. The combination of higher performance, better battery life, and the same beloved SteamOS interface made the Deck feel obsolete for my needs. While I still admire what Valve achieved, the ROG Ally X delivers that experience at a higher level. I now recommend it to anyone who wants SteamOS without settling for less power.

Will you continue using SteamOS on the ROG Ally X long-term?

Absolutely. As long as ASUS maintains driver support and the community continues to refine SteamOS for this hardware, I see no reason to switch back to Windows. The OS is constantly improving, and the Ally X gives me the freedom to explore Game Mode and Desktop Mode without compromises. It’s the handheld I always wanted—no tinkering required, just pure gaming.
