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.
"We worked hard on trying to convince these guys to start the project, and have been funding them ever since.".
This is backed up by FEX's Ryan Houdek, who thanked Valve in a recent anniversary post for "being here from the start" on the seven-year project.
While Valve has only just revealed its first Arm-based device, the company started thinking about developing for Arm as early as 2016.
By investing in technology like Proton and FEX, Valve aims to save developers from having to put in time and resources on ports. »
