Would you install a custom operating system to improve performance on your handheld gaming device?
SteamOS 3.9 is now compatible with Intel Arc G3 series handhelds, allowing users to run popular titles with significant frame rates. While the operating system functions on this hardware, users currently need specific tweaks to maintain peak CPU clock speeds.
Why it matters
This development brings Valve's gaming interface to a broader range of handheld devices beyond its original hardware. It marks a shift in Linux-based gaming compatibility, though the platform currently lacks full, native optimization for Intel architecture.
The Arc G3 Extreme relies on the B390 iGPU, which lacks XMX engine support and instead utilizes the DP4a version of XeSS. Users must install the SimpleDeckyTDP modification to maintain high CPU clock speeds on the handheld.
The players
Intel
Intel is a multinational corporation and technology company that designs the Arc G3 system-on-a-chip hardware.
Valve
Valve is a video game developer and digital distribution company that maintains SteamOS.
The details
SteamOS 3.9 allows titles like Silksong and Spider-Man 2 to reach impressive frame rates exceeding 110 FPS and 100 FPS respectively. While the software boots without workarounds, performance on the Arc G3 Extreme depends on third-party software like SimpleDeckyTDP for consistent CPU output.

The Tech Race
This development follows the pattern set by the Steam Deck hardware ecosystem by bringing a standardized Linux-based gaming experience to alternative mobile chipsets. It signals a move toward hardware-agnostic handheld gaming as developers look to replicate the console experience on diverse architectures.
Users can now leverage SteamOS to play high-performance games like Hogwarts Legacy on non-native hardware. However, gamers must be prepared to manually install the SimpleDeckyTDP utility to ensure the device maintains the necessary CPU clock speeds for a smooth experience.
The takeaway
The arrival of SteamOS on Intel Arc G3 devices expands the viability of Linux as a portable gaming platform. Enthusiasts should note that current performance requires manual modifications to keep hardware running at peak capacity.
