If a decade-old Nintendo Switch can run PC games, your next handheld doesn’t need to be x86

Arm chips have traditionally excelled in Android gaming and emulation, while x86 architecture has dominated serious PC gaming. A modder successfully ran Steam on the original Nintendo Switch, which features an Nvidia Tegra chip, due to the introduction of Arm support in Proton 11's beta version. This achievement indicates that PC gaming on handheld devices may not be limited to x86 architecture. However, running Steam on the Switch requires complex workarounds, resulting in low frame rates and various limitations. The process involved using Box64 and community-developed projects to facilitate the installation, as the Switch's outdated kernel posed challenges. Despite the limitations, the ability to run x86 games on an Arm chip suggests that hardware constraints, rather than translation feasibility, are the main obstacles. Modern Arm chips have shown the capability to run PC games, with driver issues being a significant challenge for non-gaming devices. Valve is developing the Steam Frame, a VR headset powered by Snapdragon 8 Gen 3, which runs SteamOS natively on Arm and utilizes FEX for x86 game compatibility. Early benchmarks indicate promising performance on Arm devices, suggesting a potential shift in the handheld gaming landscape. While x86 remains the safer choice currently, the barriers for Arm-based handhelds are gradually diminishing, indicating a future with more options beyond x86 architecture.

This Android gaming app might kill handheld PCs

GameNative allows users to play PC games on Android devices without an internet connection, supporting Steam titles, Epic Games Store, Good Old Games (GOG), and standalone game files. It features a known configs capability that optimizes game settings for better performance. The app's creator, Utkarsh Dalal, aims for GameNative to replace handheld PCs within two years, despite challenges related to compatibility with ARM-based chips. The Snapdragon 8 Elite and 8 Elite Gen 5 processors promise significant enhancements, and the release of Turnip drivers in early 2026 has improved gaming experiences on these devices. GameNative is free and open-source, with a monetization strategy focused on partnerships with game stores. It has recently added support for the Pixel 10 family, which uses an Imagination PowerVR GPU. The app collects user feedback to refine game configurations and plans to improve compatibility and support for third-party launchers.

Testing PC games using FEX on a high-end Android tablet can yield playable results — but the early tech is still not ready for prime time

FEX or FEX-Emu translates raw x86 instructions into ARM64 instructions, allowing Arm-based chips to run many full-fat games from the Steam Library. However, complex graphical pipelines in modern titles like Cyberpunk 2077 and Clair Obscur can cause issues with rendering geometry correctly due to community-developed graphics drivers like Turnip. Qualcomm's mobile chips were not originally designed to support desktop-level Vulkan instructions, so widespread support for mainstream games may be limited. The FEX project is ongoing, but more maturation of applications and community-made drivers is needed before FEX can be considered a feature in mainstream products.
