For the Steam Machine to change PC gaming, Valve must solve Linux's anti-cheat problem

Following months of rumors, Valve finally announced the new Steam Machine earlier this week. And while I might question the company's decision to ship a system with only 8GB of VRAM in 2026, I believe the "Gabecube" will do more for PC gaming than anything Microsoft has done in the last decade.

With SteamOS and Linux, Valve has polished away many of the things that make PC gaming unapproachable to some people. Want to set a frame limit to extend your Steam Deck's battery life? It's an easy-to-find option in the Performance overlay, not something you need to dig through multiple menus to find. Want to suspend a game? That's possible on SteamOS.

And now with the Steam Machine, Valve is poised to bring the fun of PC gaming to an entirely new audience: home console gamers. Even though I don't plan to buy one, selfishly I hope it's a runaway success. Like a lot of PC gamers I imagine, I'm ready to leave Windows behind. Over the last few years, Microsoft has proven to be a poor steward of the platform. The company seems more interested in pushing AI features few care for, rather than solving the issues that have plagued Windows for years. After all, it was only recently that Microsoft said it would tackle shader stutter, a problem that has plagued many recent AAA games. Worse yet, that solution may take years to fully implement.

I want the Steam Machine to be the revolution that brings SteamOS to desktop PCs, but before that can happen, Valve must solve Linux's cheating problem. Right now, the Steam Deck covers two of the three pillars of PC gaming: indies and singleplayer AAA games. For some people, that's enough, but it leaves out a huge section of the PC market. Nearly four years after its release, you can't play some of the most popular competitive games, and it's all because of how easy it is to make cheating software for Linux-based operating systems.

In a 2024 interview with The Verge, Riot's Phillip Koskinas summarized the issue concisely. "You can freely manipulate the kernel, and there’s no user mode calls to attest that it’s even genuine," he told the outlet. "You could make a Linux distribution that’s purpose-built for cheating and we’d be smoked."

When Valve released the Steam Deck at the start of 2022, there was some hope games like Fortnite and Rainbow Six Siege would eventually be playable on the handheld, and for a while things looked positive. Toward the end of 2021, Valve announced Proton compatibility with BattlEye. A few months later, the company did the same for Epic's Easy Anti-Cheat. There's also Valve's in-house solution, VAC, which is fully supported and means the company's own games, including Counter-Strike 2 and Dota 2, are playable on Steam Deck.

However, despite Valve's support for some of the most popular anti-cheat solutions on the market, many studios chose not to bring their competitive games to SteamOS, citing cheating concerns. Some notable examples include Fortnite, Valorant and PUBG. Those games have never been playable on Steam Deck. In fact, last fall EA withdrew Linux and Steam Deck support for Apex Legends, one of the few competitive shooters you could play on Valve's handheld.
