Confused on Steam Play and Proton? Be sure to check out our guide.

Today, Easy Anti-Cheat from Epic Games / Epic Online Services has officially announced a full expansion for Linux including native builds and Wine + Proton. This is big for Linux Gaming and the Steam Deck.

For those who don't know, Epic Games owns Easy Anti-Cheat and earlier this year they made it free for all developers making Windows games. Today this has been expanded to fully support developers doing native Linux games (and macOS too).

Not only that, this is the big one we've been waiting for — they've also expanded Easy Anti-Cheat support officially for the Wine and Steam Play Proton compatibility layers.

Earlier this year, Easy Anti-Cheat for Windows games was made available to all developers, for free. Today, we extend support to Linux and Mac for developers who maintain full native builds of their games for these platforms.

To make it easy for developers to ship their games across PC platforms, support for the Wine and Proton compatibility layers on Linux is included. Starting with the latest SDK release, developers can activate anti-cheat support for Linux via Wine or Proton with just a few clicks in the Epic Online Services Developer Portal.

Sadly it's not an automatic thing for Wine and Proton, as developers do need to actively go and do those "few clicks" but it's a huge step. In the documentation, it says how developers need to "test and activate client module updates for Linux regularly in addition to Windows". Hopefully many developers will go and do it, since it sounds like very little effort on their part. Considering just how many of the most popular games use Easy Anti-Cheat, this is the start of something massive.

Have a favourite Windows game that doesn't work on Linux currently with Proton or Wine? Looks like it's time to politely ask them to hook it up. Just a few of those that would hopefully work if developers update include:

  • Apex Legends
  • Dead by Daylight
  • Fall Guys
  • Halo: The Master Chief Collection
  • Rust

A good time to remind game developers and readers to ensure you email us news tips, especially if a game enables this to start working so we don't miss it.

It's a step in the right direction. I didn't expect EA to ever go that way.

EAC is a concern on a lot of games, and it takes the pressure off EA and puts it on the devs to activate it. Remember, even New World uses EAC. Ashes of Creation uses it too I think.

It's used a lot across the board, and now the pressure is on to the devs.
Just one thing to mention.

Wonder if Microsoft will show how much they love Linux when Halo:infinite drops... Assuming it uses EAC, pretty sure MC:C did.

So, what do we have here? Do we have a kernel module distributed with a shim wrapper?

Indeed. The only reason why keep my windows partition is so I can play, maybe, three games. And those won't work because of EAC. If I can get Division 2 to work, I'm nuking my Windows partition. The thing doesn't even want to upgrade anymore. Leave it to Rob Us Blind Microsoft to design an overpriced OS that tells you to simply reinstall.

Quoting: SalvatosNot just for Linux, but seemingly for Valve's sole benefit when it comes to supporting Wine and Proton specifically. What's going on at Epic? Maybe they intend to add Proton to their own launcher and profit from Valve's work...

I don't think it's necessarily Valve's sole benefit. Getting it to work in wine (and therefore proton) is probably more beneficial short term. You get more games working on Linux faster as opposed to trying to port to native (even if EAC now works on native).

I think this benefits every store that sells games with EAC. Valve had the biggest store and stand to gain the most through sales, some may argue they are too big. That's neither her nor there, but think of all the Steam Decks and Linux/proton installs are suddenly working; That can suddenly engage in micro transactions, etc.

I think there are a lot of benefits for everyone. I also share the idea (or hope?) that this might be the first steps to better Linux support from Epic's store.

That Halo collection works flawlessly in Proton, at least when I tested it last. I don't know if they really have much of a choice. If they create something that tries to detect Wine use, the coders will work out a way to hide it...

It still remains as a per-game opt in.

This means that every EAC game has to individually enable support for Proton/Wine. Yes, it's just a few clicks, but that means that there will absolutely be devs that refuse or just won't bother, and those games will not work.

EAC on Windows has kernel-level components, if it turns out the Linux version only runs in userspace, like VAC, then it will be much easier for cheat developers to get around. In that case it's a trade-off where enabling Linux support opens a backdoor for cheaters to more easily evade detection.

QuoteValve says kernel-level is not needed: "Anti-cheat: We recommend using user-space anti-cheat components for best results, as they can typically run in the Wine environment and provide the same level of functionality."

However, their userspace-only VAC is widely regarded as an absolute joke which is utterly trivial to bypass. Practically every anti-cheat besides VAC uses a kernel module, and nobody besides Valve uses VAC anymore despite it being offered for free to any game on Steam.

Quoting: rustybroomhandleWe're about to find out how little some of these publishers/developers actually care about Linux. "just a few clicks", can they be bothered?

Some devs might look at Proton as another thing they have to provide support for and think "It's too much effort, screw it."
