Valve has announced today that BattlEye support on Linux with Steam Play Proton has expanded, with new titles available.

As previously announced, currently all developers need to do to make it work is to email BattlEye. That's it. However, developers will still of course want time to test, so it's not exactly an instant thing. Still, it's fantastic progress and now even more games can be enjoyed.

The current list of support titles has expanded and is now:

  • Mount & Blade II: Bannerlord
  • ARK: Survival Evolved
  • Arma 3
  • DayZ (avoid the launcher, use the second option Steam gives)
    • DayZ also needs a higher max_map_count, you can up it temporarily by doing:
      ​sudo sysctl -w vm.max_map_count=1048576
      And permanently:
      echo 'vm.max_map_count=1048576' | sudo tee /etc/sysctl.d/vm.max_map_count.conf
  • Unturned
  • Planetside 2 (use "--disable-gpu" as a launch option, otherwise launcher is blank)

Hopefully by the time the Linux-powered handheld Steam Deck starts shipping in February 2022, that list will expand. I'm still personally hopeful we can see the likes of PUBG working.

You should no longer need Proton Experimental either, since Proton 6.3-8 released back in late November pulled in the BattlEye support.

In related news, Proton Experimental itself was also upgraded recently making Final Fantasy XIV playable, there's a fix for Marvel's Avengers showing prompt about outdated drivers on launch, a fix for eFootball PES 2021 and 2022 crashing on launch, a fix for audio in Mass Effect 1 from Mass Effect Legendary Edition and also improved compatibility with binary Nvidia drivers.

Regarding the comments on the official linux port of Arma 3 - that's long dead. They were having the porting done by a third party, it became too expensive* to pay that company to keep updating when they were releasing updates every couple of months and so they paused work on port updates. Then Proton came along, the game was working on linux under Proton and was costing BI nothing so they officially killed work on the port.

* Confirmed unofficially and in private by a friendly BI dev that they were being charged eye-watering amounts to keep the port updated.

I found this while searching around and it may help you so I figured I would share.

"I was able to get it working by running this command:
​sudo sysctl -w vm.max_map_count=1048576

To make it permanent:
echo 'vm.max_map_count=1048576' | sudo tee /etc/sysctl.d/vm.max_map_count.conf

Game now loads and plays fine when started with the second launch option."

Let's guess which game will get anti cheat enabled this month. Surely at least one may be enabled. Glory, fishes and a trip to north pole for the winner. One guess only! Feel free to elaborate on game you guessed.

My guess is Rainbow Six Siege. Ubisoft likes money, asking to have BattlEye enabled seems like a easy way to make money for them.

Wow that is a lot of memory mappings. I assume that Windows doesn't limit this or have a higher default, the default on Linux is 65535.

I just asked "ArmA 3 Unix Launcher" author, for adding support for DayZ into arma3-unix-launcher.

He not have time ATM, but created this issue https://github.com/muttleyxd/arma3-unix-launcher/issues/180 maybe someone convert this tool for DayZ. :D

A lot is relative. For Star Citizen the value is upped to 16 million.

Honestly, it feels a lot like the max open files where the default remained extremely low even though it was completely not necessary for current generation computers.

Well there are a lot of default limits in Linux to prevent things like fork bombing, comes from being a multi-user system at heart.

I've added the DayZ fix to the article, although for me no matter what I only get a black screen - no loading screen. Sadly this means there will be no testing or videos from me.

DayZ Launcher from https://dayzmagiclauncher.com/ its kinda working under proton (launch game not working), but you can check servers for mods and subscribe and manage them.
(all subscribed mod list available)

Maybe someone can fix it, to work under proton?

EDIT:
Looks like its broken on Windows too, i have the same error...

Hello guys,

I need help here, I can't play multiplayer on Bannerlord. The game is launching but there is any server, when I try to search a party I've got a message "Not all players are running the game with Anti-cheat".
I tried everything, Steam beta client, beta version of Bannerlord, Experimental Proton, nothing ! I have Proton BattlEye Runtime of course, I tried to check the files it's ok but I don't know why I can't uninstall it ? I have this message "An unexpected error occurred while uninstalling this application".

Help ! :-)

Thanks ;-)
