Steam Deck support

It loads up, but fails with EAC. You cannot continue or multiplayer. Singleplayer works.

Thanks, but EAC is supported by Proton now. Scum just needs to be updated by Dev though.

Proton Anti-Cheat Support

Proton supports some common anti-cheat middleware, including Easy Anti-Cheat and BattlEye.

Easy Anti-Cheat
Proton supports Easy Anti-Cheat without requiring any recompilation, but it does require you to manually enable support for your build. For the Epic Online Services version of EAC, see instructions here. For the Kamu version of EAC, follow these steps in order:
Go into the SDK Configuration settings menu on the EAC partner site and enable Linux as a client platform.
Go into the Client Module Releases menu on the EAC partner site, choose the Unix platform, and activate a module. If you cannot find the Linux module in the status dashboards, please contact EAC support.
Once that's done, download the EAC SDK and find the Linux library (\Client\Assets\Plugins\x86_64\libeasyanticheat.so) for the SDK version integrated with your game, rename it to easyanticheat_x64.so, and add it to your depot next to the Windows library (EasyAntiCheat_x64.dll).
Lastly, on the Steamworks site, publish a new build of your game containing the new depot contents. (You don't have to make any changes to the game executable, just include the new files in the depot contents.)

Known Proton Issues

Below are a few recommendations around areas that have been known to be Proton compatibility issues and likely to induce delays in Proton fully supporting a given title after it launches on Steam:

.NET / WPF: Our recommendation is to use standalone technologies like Qt for launchers instead of OS-dependent frameworks like .NET / WPF. For best results, skip separate launchers altogether and integrate their functionality into the game client UI instead, where controller support is likely better.
Media Foundation: To save additional bandwidth and disk use, we recommend using standalone codecs like VP9.
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. Kernel-space solutions are not currently supported and are not recommended. Note: we have been working with most anti-cheat technology providers to provide Proton compatibility. If your solution currently isn't working, please reach out to both your vendor and Valve for support.
Anti-tamper / DRM: In general we don't recommend use of such solutions across any PC platforms, as they may impact disk usage and overall performance. Getting them fully functional in the Wine environment can take some time and add significant latency to getting your title supported.

This has been discussed a couple of times. It's not as simple as people think. And it isn't the game they need to upgrade. They would need to upgrade the SDK of EAC that the game is using, which isn't an easy task. Epic only added Proton support for the EOS version of EAC.

they just need to add wine64 eac libraries, and if they really have old eac version why even have it in first place?
