Gradually, more Windows titles with kernel-level anti-cheat protection are becoming compatible Steam Deck games. Umamusume: Pretty Derby may soon become verified for the handheld gaming PC. Aided by the Proton compatibility layer, the popularity of Linux gaming is on the rise.
One frustration Steam Deck owners face is with Windows-based games that use a kernel-level anti-cheat. Apex Legends, Fortnite, and EA Sports FC are just a few of the many popular titles unavailable to these gamers. However, recent developments have given Linux users hope for more compatible Steam Deck games. Umamusume: Pretty Derby is the latest title to feature anti-cheating technology that now works on the handheld.
GamingOnLinux recently tested Umamusume: Pretty Derby, which uses the CrackProof protection. The unusual Japanese-developed game involves training anime horse-racing jockeys. Now, the site confirmed that it runs without issues on the handheld gaming PC. While listed as Steam Deck playable, only some small fronts prevent a Steam Deck verified rating. GamingOnLinux also had success booting the game on a desktop Linux system with Kubuntu 25.04.
After its release in December 2024, Proton 9.0-4 has further boosted support for Windows games on SteamOS and Linux. Yet, many multiplayer and competitive titles with kernel-level anti-cheat remain unplayable. Developers may hesitate to add their protections to the OS, fearing potential vulnerabilities. Still, other critics accuse companies of simply not making the effort.
In the past, publishers argued that Linux gaming only represented a small market share. Still, support for the efficient open-source OS has been growing. The Steam Deck is major reason for this trend, powered by Valve’s prolific marketplace.
Demanding system requirements are another reason why some Windows titles aren’t verified Steam Deck games. On the other hand, SteamOS is now an option for handheld gaming PC alternatives, such as the Lenovo Legion Go S. Even if Valve doesn’t release a new machine, other manufacturers will likely debut powerful options. With anti-cheat measures now less of a factor, the future of Linux gaming looks brighter.
