Valve hopes the Steam Machine will make devs pay more attention to Linux anti-cheat support (www.pcguide.com)

Steam Machine’s upcoming release means more people will be playing games on Linux, specifically SteamOS. The idea of ditching Windows for gaming is becoming more attractive, as the Steam Machine is first-party desktop-level hardware that’s optimized for Linux-based SteamOS. The biggest hurdle for Linux gamers right now is a lack of support for many anti-cheats – particular those that require kernel-level access. But with the release of the Machine, Valve hopes game devs take notice.

Steam Machine seems to getting the most attention out of Valve’s latest hardware launches. The Steam creators announced the new console-like mini PC alongside the Steam Frame VR headset and new Steam Controller. Even the Frame runs on SteamOS, which means Valve now has a trio of first-party hardware on Linux (including the Steam Deck handheld).

We have memory security, virtualization and antitampering features

As someone who games entirely on Linux and wants multiplayer to work out, the features you're referring to are for keeping the application contained by the kernel, not the other way around. On a system where the user has full autonomy, no application should be able to know what is going on outside of its user space, and I don't want it to.

It'd be nice if it was a solved problem, but it's not. From consoles to phones to windows, currently the industry relies on you not having autonomy over your device for anti-cheat to work. Every other solution is either expensive (obfuscation arms race), or untenable (real time, high resolution server side validation of every property of every player).
