Since the release of the Steam Deck, Valve fans have gotten very familiar with the idea of the Proton compatibility layer that allows games written for Windows to run capably on the Linux-based SteamOS (though Valve's efforts in this realm date back further than that). To get more games running on the SteamOS-powered Steam Frame, though, Valve is relying on two additional compatibility layers that are new to the Steam architecture.

The first, FEX, is Valve's port of fex-emu, an open source project that emulates x86 processor instructions on an Arm chipset. Since 2018, what started as a small cross-platform emulation project has grown to include "an advanced binary recompiler that supports all modern extensions of the x86(-64) instruction set," according to the Fex website. The emulator can also make calls to graphics libraries like OpenGL and Vulkan to reduce overhead and uses "code caching to minimize stuttering as much as possible," according to Steam's own developer documentation.

While Proton was based on the pre-existing Wine conversion tool, Valve engineer Pierre-Loup Griffais told The Verge last year that the company has been funding Fex lead developer Ryan Houdek since the project was just a prototype. Back then, Valve was already anticipating that "close to a decade of work [would be] needed before [Fex-emu] would be robust enough people could rely on it for their libraries."

Valve's Steam Deck handheld has been largely unavailable to buy since mid-February, a victim of the RAM and storage shortages that have been driving up prices for most consumer tech since the fall of 2025. The good news is that the Deck is back in stock on Valve's site and ready to ship in three to five days; the bad news is that it appears to have returned because somebody wished for it on a monkey's paw.

The 512GB version of the OLED Steam Deck now sells for a whopping $789, $240 more than its previous $549 price. The 1TB version (which also includes an anti-glare screen coating, a slightly nicer case, and an "exclusive startup movie and keyboard theme") will now run you $949, a $300 increase from its old $649 price. The old $399 base model with 256GB of storage and the older LCD screen has been discontinued, though this had been announced well before these price increases took effect.

These prices are particularly hard to swallow for a nearly 3-year-old revision of an over-4-year-old handheld PC. If there's a saving grace for Valve, it's that most competing handhelds from the likes of Asus and Lenovo are also pushing or exceeding that $1,000 mark. Of the Deck's major competitors, only the $600 Asus ROG Xbox Ally (and its AMD Ryzen Z2 A processor, which is very similar to the Deck's semi-custom AMD chip) is significantly cheaper than the Steam Deck.
