Have you found yourself wondering why some of your favorite multiplayer games are missing from the Steam Deck? You're not alone. A significant factor contributing to this issue is the reliance on Windows-specific kernel-level anti-cheats, which are unfortunately incompatible with the Steam Deck's Linux-based operating system.

Kernel-level anti-cheat software is designed to be thorough in its effort to detect cheaters by having deep access to system resources, but it comes with its own risks. This type of software can potentially compromise system security because it can interact with sensitive areas of your computer.

In a recent interview with AUTOMATON, Valve's Steam Deck designer Lawrence Yang and programmer Pierre-Loup Griffais acknowledged the compatibility challenge and stated that Valve is actively keeping an eye on the growing trend of games utilizing kernel-level access. In a bid to curb this issue, Valve has previously collaborated with anti-cheat giants like Easy Anti-Cheat and BattlEye to make the integration process smoother for game developers looking to support the Steam Deck.

Unfortunately, this situation means that several notable titles, including EA's popular Apex Legends, recently removed support for the Steam Deck. EA expressed concerns that Linux could create pathways for various exploits and cheating, leading to their decision.

On a positive note, Valve is working to keep players informed; Steam now provides warnings for games that utilize kernel-level anti-cheat systems, giving gamers an indication of the potential risks involved with running those titles on the Steam Deck.

This ongoing discourse highlights not only compatibility issues but also raises critical questions surrounding security and the future landscape of gaming on Linux-based platforms. As gaming technology evolves, it will be interesting to see how Valve and other developers navigate these challenges.
