Valve’s made it clear that it wants every game on Steam to be playable on the Steam Deck at launch, and one of the few major obstacles to that goal has been anti-cheat technologies that only work on Windows. That problem has now been at least partially solved—Epic, which bought Easy Anti-Cheat back in 2018, announced on Thursday that it’s added support for both Linux and Mac OS.
And it gets better: Easy Anti-Cheat doesn’t just offer native Linux support now, but also support for Wine and Proton, the compatibility layers used to run Windows applications on Linux. Proton is what Valve is using to make the entire Steam library playable on the Steam Deck, even though relatively few games have native Linux ports.
“Starting with the latest SDK release, developers can activate anti-cheat support for Linux via Wine or Proton with just a few clicks in the Epic Online Services Developer Portal,” the update reads.
