It may come as no surprise that Valve has invested in emulation tech for Arm-based hardware, having just announced its first device running an Arm chip. But beyond its own hardware, Valve’s support of open-source emulation projects may have laid the groundwork for playing your favorite PC games on Arm devices like mobiles and tablets–no ports necessary.
Valve’s upcoming Steam Frame headset is the company’s first Arm-based device, making use of the open-source FEX emulator to run Windows-native games. As it turns out, Valve has had more of a hand in FEX’s development than it initially appeared. In an interview with The Verge, Valve engineer Pierre-Loup Griffais revealed that Valve actually initiated the FEX project, and has been largely responsible for its development.
