In a groundbreaking leap for open-source computing, the experimental felix86 emulator has achieved what many deemed impossible: running Steam and demanding AAA games natively on RISC-V processors. This milestone, confirmed by developers and early testers this week, signals a potential revolution for the burgeoning RISC-V ecosystem—long constrained by limited gaming support.
The Emulation Breakthrough
Felix86, a Linux-based dynamic binary translator, now seamlessly executes x86/x86-64 applications on RISC-V architectures. After months of optimizations targeting Vulkan API compatibility and CPU instruction translation, the emulator successfully booted Steam and ran titles like Cyberpunk 2077, Elden Ring, and Baldur’s Gate 3 at playable frame rates on SiFive’s high-end RISC-V development boards.
"Our goal was never just compatibility—it was performance," lead developer Lin Wei told GamingOnLinux. "By reworking memory handling and GPU passthrough, we’ve reduced overhead to 15-20% versus native x86 systems. That’s unheard of for architecture translation."

Why It Matters
RISC-V—a royalty-free, open-source instruction set—has gained traction in embedded devices and supercomputers but struggled to penetrate mainstream consumer markets due to software gaps, especially in gaming. Felix86’s acceleration layer bridges this chasm, potentially enabling future RISC-V laptops and handhelds to tap into Steam’s 50,000+ game library.
Early adopters report success running Proton-enabled titles via Steam, with lighter games like Hades and Stardew Valley performing flawlessly. Even heavier AAA titles now hit 30-45 FPS at 720p/1080p on flagship RISC-V hardware.

The Road Ahead
While hurdles remain—like DRM compatibility and ray tracing support—felix86’s rapid progress hints at a near future where RISC-V devices compete with x86 in gaming. "This isn’t just an emulator; it’s an emancipation tool for open hardware," said open-source advocate Maria Chen. "Imagine a Steam Deck successor running RISC-V silicon. That’s now plausible."
The project’s code will go public on GitHub next month, inviting developers to refine what could become gaming’s most disruptive open-source tool since Proton itself.
