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).

Microsoft even sees it as a big mistake. They're creating APIs that won't require anti-cheat to be in the kernel like that. There shouldn't be any reason it needs to be in the Linux kernel.

That said, "don't trust the client" is a nice thing to say, but it's basically impossible to make games work like that. There are certain protocol design considerations that are needed for fps games to work in multiplayer with somewhat laggy connections, and they're not completely compatible with "don't trust the client". If we all had the fiber optic connections and IPv6 that we were promised in the 90s, things would be different. The wack-a-mole game against cheaters is the best that can be done otherwise.

What on earth would ipv6 have to do with it?

It can be routed more efficiently and has generally lower latency. Though how much it matters in practice is debatable, and real world data has fluctuated.

One thing it definitely enables is easier setup of home servers for games without NAT nonsense.
