Proton 11 ARM beta on Ayn Odin 2: Hollow Knight exceeds 100 FPS and sparks the debate on ARM handhelds

Proton 11 ARM beta running on the Ayn Odin 2 shows Hollow Knight: Silksong over 100 FPS; other titles and storage issues indicate the path for future ARM handhelds.

A new beta of Valve's Proton 11 ARM is beginning to show its potential on the Ayn Odin 2 Portal. By upgrading Rocknix to internal storage, the experience proves to be snappy, with the Steam client running as a native ARM Linux binary.

Even though the games still rely on the Proton + FEX stack, lighter titles respond well to this configuration.

Performance in key games

• Hollow Knight: Silksong exceeded 100 FPS on the 120 Hz panel, with the frame limiter disabled.
• Cuphead stayed between 60 and 70 FPS.
• Half-Life 2 reached over 120 FPS.

Storage and installation

Devices like the Ayaneo Pocket S2 and the Konkr Pocket Fit were observed running Rocknix from a microSD card, as the installation path to internal memory is not yet fully supported. This resulted in significantly slower downloads and installations.

Compatibility notes

According to ETA Prime, there are still a few issues: Witcher 3: Wild Hunt did not relaunch after the first session, and Half-Life 2 required a USB keyboard and mouse, as the built-in controller did not bind in-game. Random black screens and crashes were also observed during the tests.

What is missing for ARM to become a stable alternative

The issue of ARM kernel anti-cheat remains open, as translation layers have not yet completely solved the problem. For now, the ecosystem seems more geared towards enthusiasts than actually replacing the Steam Deck, but the foundation for a new generation of ARM-based handhelds has already been laid.
