EAC is a way for multiplayer games to protect their online experience, but it currently does not work with Proton as the service either fails to load or crashes games in progress before long.

@ysy95109 Hi, EAC already has EAC Linux Wine / Proton Support, as long as the game enables it.

I'm having the same issue, unfortunately. But for me the game starts, but then presents me with a black modal window and a blue button in the middle with the localized text "Verlassen" (Leave / Exit). I cannot get beyond this point. I'm using Proton 6.3 and Proton Experimental. I'm not sure if this is already EAC blocking me out, or if it is a rendering problem, but whatever it is, EAC will be the major hurdle I think.

Please consider enabling Linux support in EAC. I'd be such a shame to not be able to play the final product I've backed and waited for so long. :(

@holyfight6 where did you find that EAC log?

That is the EAC error window.

where did you find that EAC log?

It's in "your_steam_library_dir/componentdata/1810920/pfx/driver_c/users/steamuser/Application Data/Easy Anti Cheat".

For Developer: I found the main reason of EAC not working on proton. EAC actually working on Proton, but with a exception the url that provide to EAC cdn=https://modules-cdn.eac-prod.on.epicgames.com/builds/136/1992dddf-4269-4b28-b0a9-207a02c1a2a7/{{system}} The {{system}} in wine will pass wine64 which the full url is https://modules-cdn.eac-prod.on.epicgames.com/builds/136/1992dddf-4269-4b28-b0a9-207a02c1a2a7/wine64 but the EAC website is actually not accept wine64, It will return access denied. If I change {{system}} to wow64_win64 which is win10 EAC given to EAC, and it working. so....，EAC website is not actully complete support wine at all, it should pass windows version of {{system}} to EAC or the EAC should accept wine64

[holyfight6]

@l12436 Can confirm it works for me too.

If I change {{system}} to wow64_win64 which is win10 EAC given to EAC, and it working.

i'm a ubuntu noob, using whatever steam installed (proton)... how do i change {{system}}?

@johnathandarkly It's in the EAC config file shipped with the game, you can simply use the "Browse local files" option to open the path, the file is called "FallenDoll.exe.eac".

Wow, that is interesting that it indeed does work if you replace the placeholder {{system}} with wow64_win64.

I had the impression that the developer usually needs to also provide a binary for wine64 (probably by enabling a flag in the engine when compiling the game) - that was how it worked for a different game in the past for me. There was one military shooter that also used EAC and was one of the very very few games, that actually had provided an EAC binary for wine64 and it worked flawlessly out of the box. That was months ago, even before they said that proton compatibility for EAC can be enabled now - maybe it's just easier now to do so.

So, I'd say that is a nice workaround, but not sure if this is the proper solution. It won't work out of the box that way for sure, but it's at least something. :)

with 0.4.5 game drops out before title screen on my ubuntu machine. it lasts a little longer with the wow64_win64 edit, but it still can't quite make it.

[l12436]

yes, I can confirm, latest update break wine compatible.

[johnathandarkly]

still no luck with 0.4.7. could be related to my lockout from harem mode, but i can still no longer get to title screen with ubuntu/proton.

[johnathandarkly]

I thought there was a 0.4.7.1 patch that got Proton going again. This isn't obvious from 0.4.8... which still isnt working on my ubuntu build.
