Epic Games is taking significant strides to improve the gaming experience on Windows-on-Arm devices by integrating support for its Easy Anti-Cheat (EAC) software. This development addresses a longstanding compatibility challenge, enabling popular titles like Fortnite to run natively on Arm-based systems.

Background: The Challenge of Anti-Cheat on Windows-on-Arm

Windows-on-Arm devices, powered by Qualcomm's Snapdragon processors, have faced compatibility issues with certain software, particularly kernel-level anti-cheat systems. These systems are essential for maintaining fair play in online gaming by preventing cheating and exploits. The lack of native support for such anti-cheat solutions on Arm architecture has limited the availability of many multiplayer games on these devices.

Epic Games' Initiative

In March 2025, Epic Games announced a collaboration with Qualcomm Technologies to bring EAC support to Windows-on-Arm devices. This partnership aims to make Fortnite available on Snapdragon-powered Windows 11 Arm devices later in the year. The integration of EAC is a crucial step, as it allows developers to implement anti-cheat measures on Arm-based systems, thereby expanding the range of multiplayer games accessible to Arm users.

Technical Details

The integration involves adapting EAC's kernel-level drivers to function on Arm architecture. This adaptation is facilitated by Qualcomm's Snapdragon X Series processors, which offer enhanced performance and efficiency for gaming applications. By updating the Epic Online Services SDK to include Arm support, Epic Games enables other developers to incorporate EAC into their games, promoting a broader adoption of anti-cheat solutions on Arm devices.

Implications and Impact

The addition of EAC support signifies a pivotal moment for Windows-on-Arm gaming. It not only enhances the security and integrity of online gaming on these devices but also opens the door for a wider array of multiplayer titles to become available. As more developers adopt this compatibility, Arm-based Windows devices are poised to become more attractive to gamers seeking portability without compromising on performance or security.

Looking Ahead

While the initial focus is on Fortnite, the successful implementation of EAC on Arm devices is expected to encourage other game developers to follow suit. This momentum could lead to a more vibrant gaming ecosystem on Windows-on-Arm platforms, benefiting both developers and players.
