Valve's Steam Machine limited by Linux anti-cheat compatibility

13. November 2025

Valve has announced the Steam Machine, a compact console-like PC running Linux-based SteamOS, set for launch in early 2026. While it targets 4K gaming at 60FPS and supports many titles, it cannot run popular multiplayer games requiring unsupported kernel-level anti-cheat systems. Developers may need to expand Linux support for broader compatibility.

Valve announced the Steam Machine on November 13, 2025, as a dedicated gaming rig resembling a compact console for living room use on TVs or monitors. The device runs SteamOS, a Linux-based operating system derived from the Steam Deck, and aims for 4K resolution at 60 frames per second in most games. It plays existing Steam library titles but faces limitations with modern multiplayer games that mandate kernel-level anti-cheat software incompatible with Linux.

Supported anti-cheat systems include BattlEye, used in PUBG, Rainbow Six Siege, and Destiny 2; Easy Anti-Cheat, employed by Rust and Fall Guys; and Valve Anti-Cheat for titles like Counter-Strike 2 and Dota 2. However, RICOCHET, required for Call of Duty: Black Ops 7, lacks Linux support, as does Riot's Vanguard for Valorant and League of Legends, and EA's Javelin Anti-Cheat for Battlefield 6 and EA Sports franchises. One source claims Fortnite, which uses Easy Anti-Cheat, will not run, while another indicates Easy Anti-Cheat supports Linux, highlighting a potential discrepancy in current implementations.

Valve also unveiled a second-generation Steam controller and the Steam Frame VR headset, both integrating with SteamOS, which is expanding to ARM architecture. No pricing details were provided, but the launch is slated for early 2026. Users can install Windows as a workaround, though this may reduce performance and disrupt the console-like experience. Valve may introduce a verification program similar to the Steam Deck's, and workarounds could emerge to verify Steam Machine integrity without full Linux support for anti-cheat. The success of SteamOS depends on developers pushing for broader compatibility, potentially challenging Windows dominance in gaming.

Was die Leute sagen

Reactions on X to Valve's Steam Machine announcement focus on its Linux-based SteamOS incompatibility with kernel-level anti-cheat systems, preventing popular multiplayer titles like Battlefield 6, Call of Duty, Fortnite, and Apex Legends from running. Negative sentiments dominate, with users calling it a major limitation that undermines the console's appeal for online gaming. Skeptical voices question its market success given weaker hardware and persistent compatibility issues, while optimistic opinions suggest it could pressure developers to improve Linux support or reduce reliance on invasive anti-cheat. Neutral discussions note that as a PC, users can install Windows for broader compatibility, though this defeats the plug-and-play purpose.

See this is what I'm trying to tell everyone who's excited for steam machine, half of the steam library will not work at all, because linux doesn't support anti cheat system. So no battlefield, no cod, no fortnite and all other online games

The issue is that the worst multiplayer slop has invasive Windows-only anti-cheat, and the Steam Machines are running Linux, with Proton/Wine as a compatibility layer for running Windows games.

It works for basically everything except games deliberately modified to not work.

No, the real struggle is actually the lack of anti-cheat support for Linux, meaning stuff like Valorant and Apex can't run on SteamOS. CS2 works, but FaceIt matches are a no go.

Basically, if a game requires you to use a kernel-level AC, you're SOL.

Steam OS uses Linux as its base. Anti cheat has been an issue for Linux forever

The devs for those multiplayer games use kernel level anti cheat that won’t run on Linux

Average gamer isn’t going to know how to change OS when they buy PCs with windows already preloaded

Funny enough it will actually not play quite a few of these titles simply because it cannot.

Thanks to anti-cheat built into them and Linux not supporting it.

This is a huge issue for these devices running steamOS as a vast majority of online multiplayer games today require…

Did you read the article? It's not about getting kernel level anti-cheat to work on Linux, it's Valve discussing why they think the Steam Machine will discourage developers from using kernel level anti-cheats at all.

Kernal level anti cheat doesn't work on linux distros so you can't play games like BF6. And on top of that its linux. Most games run through windows emulation like wine, and a lot of steam games either don't work on steam os or are not optimized for it and are buggy.

Can't play Anti Cheat games... like Call of Duty,Fortnite,Battlefield 6, Destiny and so on is the biggest weakness of the Linux Steam OS

— BTMaverick707 (@BTMaverick707) 13 नवंबर 2025

You're just coming out of the closet as a retard, dang!

No one in their right mind will buy Steam Machine over a PC or whatever the next Xbox PC/Console hybrid is

SteamOS can't even play loads of games due to anti-cheat

Will Battlefield 6 Work On Steam Machine? Valve Hopes Its New Hardware Will Prompt a Fresh Discussion With Developers Over Kernel-Level Anti-Cheathttps://t.co/oZH4utmEv7#steammachine #steamos #battlefield6 #videogames #gaming

The Steam Machine has one obstacle to get mainstream audiences.

Valve needs to find a way to get Fortnite, Battlefield, or COD to work on it. SteamOS, which is Linux, means many games using kernel level anti-cheat won't work.

If they can get around that, watch out.

Valve has to solve the Linux multiplayer issues that exist to this day or you will not buy a Steam Machine or Gabecube for multiplayer as it won't work for those type games due to anti-cheat software.

Battlefield 6 und Kernel-Level Anti-Cheat: Auswirkungen auf SteamOS, SteamDeck und Steam Machine #Battlefield6 #Battlefieldhttps://t.co/xSYZ3VdIrZ

Valve has been trying for a while to get kernel-level anti-cheat support for SteamOS. Devs have been more inclined to include official Linux support since the Deck launched, if the Steam Machine takes off I think it’s a safe bet that they’ll have more incentive to make it work.

People saying Steam Machine can't play certain games due to anti cheat not currently supported by SteamOS are ignoring the fact it's a PC and you can install whatever OS you want including the ability to dual boot whichever OS you need

Welcome to PC

the problem rn is that with steam machine using SteamOS (hence, using Linux) idk if you could play games like Fortnite right out of the gate, cause the whole anti cheat being kernel level and stuff

— Seihn (@seihn18614) 13 नवंबर 2025

Battlefield 6 gilt wegen Kernel-Anti-Cheat als SteamOS-Problemtitel. Valve sieht mit der Steam Machine neue Chancen.https://t.co/IJuZVmoLGi
