Linux Heroic Launcher EAC Problem

[hallow mountain]

I tried to plan chivalry 2 with Linux and the heroic launcher but I cannot play because of the EAC warning. It’s the epic games version.

I tried every advice on Reddit etc but still not working.

Any tips or solutions?

[digital widget]

hi, im in the same boat

did you solve it?

[sonic plover]

ادخل علي طريقة الحل الي وجته في النت وستشتغل مثل ماشتغل معه هو

[sonic plover]

Enter the solution method I found on the internet and it will work just as it worked for him

[digital widget]

thanks for your reply, but even with the same screenshots, and all, i still get the message, and yeah I delete prefix folder everytime i try.

[sonic plover]

Try a different version of Proton, like he did.

[brazen gale]

linux
gaming

[somber hornet]

Did you figure out how to fix it? Also having problems with it lmao

[digital widget]

not yet, i was comparing the config with my friend with cachyOS and having the same configuration he can play without issues and I dont with Bazzite

[somber hornet]

I'm also using Bazzite! Probs the distro

[digital widget]

damn.. i updated last week just in case but didnt work for me. maybe i can try later at night if my daughter gives me some time 🤣

[somber hornet]

You mean update as in change the distro? Good luck anyway and if you find a solution for Bazzite, pls tell me!

[digital widget]

im pretty sure that the game in steam will run without problems, i think its something to do with heroic

[somber hornet]

the game's on sale on steam rn

Imma get it and tell you if it works then

[somber hornet]

@digital widget Still doesn't work. I think Bazzite has problems downloading/detecting/running the "Chivalry2-Win64-Shipping.exe" file

[digital widget]

in protondb people claim it works i saw some reports using bazzite i think

im not home, so i cannot do any research now

[somber hornet]

Oh yeah you're right. They use Proton Beta, but I have no idea how to do that

[digital widget]

in your steam library, right click in your game, properties, look for a section called COMPATIBILITY and select proton experimental (thats the last version of proton available)

[somber hornet]

Yup did that, also did not help

Unless I gotta delete the prefix folder beforehand again, although I don't know where it is lmao

[digital widget]

in steam in the cogs menu, there is a way to delete proton cache or something like that

this dude got it working 2 years ago with bazzite

[somber hornet]

Ye found this too, did it and didn't help

[digital widget]

sorry my friend, maybe you can still ask for a refund

thanks for trying though

[somber hornet]

Lmao, we did our best

[somber hornet]

didn't find that btw

[digital widget]

when you select the game in steam library, there is an icon ⚙️ on the right side, and there it should be a way to delete proton cache

[somber hornet]

Yeye but I didn't find any "delete cache" option

[digital widget]

maybe im wrong sorry 🥲

[somber hornet]

Lmao, maybe the last update to Chivalry broke Bazzite compatability, idk

[digital widget]

looks like it

i just created a post in bazzite's reddit

https://www.reddit.com/r/Bazzite/s/zBQKO1geLt

im in my phone so I dont have much details to share

[somber hornet]

I'll add to it later

[somber hornet]

@digital widget If you want an update on my Steam situation: I can't launch the game anymore :')

[digital widget]

really? how so?

[somber hornet]

No idea lmao

[digital widget]

i gave up and uninstalled from heroic the game

the developers, in general, are not interested in giving support to linux for anti cheat it seems. I hope the upcoming steam machine sells a lot that will make devs change their opinion.

[somber hornet]

Shame tho, it was a very fun game

I recommend you check kingdom come: delivarence out tho. It's singleplayer but has a similar combat system

[digital widget]

yeah i think my gf played it and she loved it... now that you mention it I really need to check that out.
thanks for the recommendation dude... that games looks like the new tv series of the games of thrones, the knight of the 7 kingdoms lol

[somber hornet]

Game of Thrones was never cup of tea, but trust me the game and it's sequel are really good! Especially if you know a bit of german ;)

The games take place in Böhmen, which is now a part of the czech republic but once was part of the holy roman empire!

[digital widget]

tbh they shit in got in this new series... literally in the first minutes of the show the protagonist who's a dumb as fuck peasant, takes a shit when the game of thrones song plays 🤣
it reminds me of fable, its got farts, blood, and jokes everywhere... so different from game of thrones

ill play both then when i got time 🥲

[vapid nexus]

any fix?

I was playing the game just fine few months ago, now It's not working

[potent meadow]

it works!
1st option: u need GE proton in your heroic launcher. u can install if with protonup-qt. might already be enough without anymore tinkering. stop here when it works.

2nd option: since i still got the EAC block messages i use a custom wine that hides wine from the game so EAC is less annoying.

the runner got vkd3d-proton compiled in so u can even play with directx12

[potent meadow]

use this precopmpiled runner https://codeberg.org/Vogelhaufen/chiv2-runner/src/branch/main/

extract and add /bin/wine as a custom wine runner

enable vkd3d for dx12

[potent meadow]

https://streamable.com/dkq3gu
this is the result

[potent meadow]

^ set new custom winerunner in the chiv2 options. done

[vapid nexus]

what version of proton GE you use?, and what's the version of heroic?

I still get kicked out even with GE

[potent meadow]

i used to tuse latest ge-proton (32) and Heroic-Version 2.20.1 - but as i already mentioned it didnt work for me but apparently for others. I use my linked #1468361815384653824 message wine runner to work around the EAC kick.

[potent meadow]

Btw the game defaults to DLSS version 2 but u can swap DLLs to use DLSS version 4 with the following env vars:

Only works with the modified runners.

PROTON_ENABLE_NGX_UPDATER="1" DXVK_NVAPI_DRS_NGX_DLSS_SR_OVERRIDE="on" DXVK_NVAPI_DRS_NGX_DLSS_RR_OVERRIDE="on" DXVK_NVAPI_DRS_NGX_DLSS_SR_OVERRIDE_RENDER_PRESET_SELECTION="RENDER_PRESET_K" DXVK_NVAPI_DRS_NGX_DLSS_RR_OVERRIDE_RENDER_PRESET_SELECTION="RENDER_PRESET_K"

They can be set in the heroic launcher game options > Advanced > env variables

as of now DLSS 4.5 doesnt work for (me) since its crasing the game.

v310.5.2 = DLSS 4.0
v310.5.3 = DLSS 4.5

[vapid nexus]

it's working again, thanks a lot!

[vapid nexus]

I have an rx460 so this won't do for me, the game is running fine however

[somber hornet]

I'm too dumb to understand that, can you walk me through the steps please?

Also, @digital widget

[digital widget]

wow you guys got it working!? thanks for the reply Yatashi. I read everything and I still not familiar with terms like "winerunner" and precompiled runners. So I frankly have no idea... yet

but maybe we can feed this to an AI 😁

[digital widget]

btw i tried the game, about 10hours in.. and I still don't know how to properly fight with a sword. got stuck in a sidequest using the girl from the mill, and lost interest quickly... had to uninstall. how come there is no way to get back to the original character? 🤨 and i also got mad with the UI and complex object grabbing system. it would have been much easier to just highlight the object that can be picked, or the box that can be openned. I guess i am too fed in modern standards like skyrim, witcher or cyberpunk. even if the game is not so old, it has the old rpg vibe, realistic but classic at the same time. sadly i think its not for me. not a bad game but if I had hundreds hours to play maybe i would enjoy it more.
buuut thanks for the commendation, maybe in future i would give it a second chance

[somber hornet]

To fight the best with a sword you gotta get the masterstrike ability from tomcat. Other than that, feinting is really important! Basically, just before attacking, change the direction of your strike. Lock on also helps!

[digital widget]

is the video down or.. is it just a screenshot?

[potent meadow]

It is down

Did u guys make it work?

[somber hornet]

It took about half an hour of trying to figure out what "extract file" meant, but then I got it working :3 I didn't have to enable vkd3d for dx12 tho, don't even know what that is

Do you think I can use that custom wine on steam?

[somber hornet]

@digital widget did you get it to work?

[digital widget]

thanks for checking it but i didnt try yet 🥲 last night when i finally had some time at midnight i completely forgot about it. maybe tonight

[somber hornet]

@potent meadow Do you think I can use that Winerunner for Steam as well?

[digital widget]

I'm installing it right now

aaand it works

🙂 thanks so much @potent meadow 👏👏👏👏👏 It really was as simple as downloading the file from the link, unzip, in Heroic Launcher Settings add the custom wine folder, and then in the Library, in Chivalry 2, settings, use the custom wine (instead of proton-ge select the custom, which will be available as the last item in the selector), and it works out of the box at first install. just awesome

I'm not smart enough but I BELIEVE, that with protonUP-QT program, you can add the same unzipped file directory of the custom wine, to be used for steam. Then you would open steam, and under compatibility it should be available... But i haven't tested it yet

[digital widget]

nah forget it, protonup-QT only allows you to add specific proton/wine runners, not custom ones.. or at least I didn't find a way to do it.
Sorry @somber hornet

[somber hornet]

Ah damn. We gotta play a round some time tho

[digital widget]

so you got it working in heroic?

[somber hornet]

Oh yeah like yesterday

I just wanted it to work in steam as well cuz I got the legendary edition there

[digital widget]

cool, one thing that bugs me in that in the menu the game is like 5 fps

but ingame is perfect

[somber hornet]

I don't have that problem

[digital widget]

maybe it's a setting, Idk

I don't care much for now, I'm gonna play now some rounds

since I have some free time now

[somber hornet]

Have fun, Imma sleep. Show those Mason heretics what true Agathian steel is!

[digital widget]

lmao looks like ally greta thumberg just killed me LOL XD

good night, and thanks for everything

[potent meadow]

i don't play on steam but some1 could build GE-Proton with my patches. i don't think u can use my wine runner out of the box on steam and i'm to lazy to do it 😄

maybe later when i'm in the mood, i got the game on steam too, don't ask why

happy its working for u guys

[potent meadow]

Update: i tried proton-experimental on steam and it just works

[somber hornet]

I tried a lot of stuff and nothing has worked so far, thanks for your efforts tho!

[somber hornet]

@hallow mountain

If you still have the problem, do what Vogelhaufen here describes #1468361815384653824 message

[somber hornet]

When using any Proton (Experimental or others) plus running "eval $(echo "%command%" | sed 's/Chivalry2Launcher.exe/TBL/Binaries/Win64/Chivalry2-Win64-Shipping.exe/')" , instead of the usual EAC error, this one shows:

[potent meadow]

yeah thats cause the eac is not used if u skip the launcher

[somber hornet]

If I don't use this command, the usual error shows

[potent meadow]

ha thats weird since its working for me on proton experimental

[potent meadow]

@somber hornet i build a proton version, it works for me, but this is the first time doing this, expect it not to work for u

uploading rn

[somber hornet]

Thanks for trying at all, seeing as how you have no obligation to do that :D

[potent meadow]

[potent meadow]

No worries im used to fix broken Games and I was mad when I noticed my favorite toxic slasher doesnt work anymore

if it still doesn't work u might to delete your EAC dir

[somber hornet]

Imma try it out in like an hour and report back to you

[somber hornet]

It did not work, same normal error

[potent meadow]

SteamLibrary/steamapps/compatdata/1824220/pfx/drive_c/users/steamuser/AppData/Roaming/EasyAntiCheat/ delete "EasyAnticheat"

its where your steamlibrary is installed

then try again

when it still doesn't work maybe verify files

also the contents of anticheatlauncher.log could be interesting. you can find it in SteamLibrary/steamapps/compatdata/1824220/pfx/drive_c/users/steamuser/AppData/Roaming/EasyAntiCheat/<some random name>/<some randomname>/anticheatlauncher.log

and the extact error u getting when starting the game

[somber hornet]

The error when just using your Proton runner

Error after deleting the "EasyAntiCheat" folder with your custom runner

Error after deleting the "EasyAntiCheat" folder with Proton Experimental

[potent meadow]

delete SteamLibrary/steamapps/common/Chivalry 2/EasyAntiCheat and try again. im out of ideas for now. maybe reinstalling in your case 😮

[somber hornet]

did that before reinstalling to try your stuff out lmao

[potent meadow]

the eac log is clean af

[somber hornet]

currently verifying the files, maybe that helps lmao

[somber hornet]

I deleted the game and reinstalled it before using your runner, since I deleted EAC from the path above

[somber hornet]

when doing that

Maybe the fact I'm using the Bazzite distro helps

Aside from that, I can still play on epic so it's not that bad, I just had some in game currency on steam that's all

[potent meadow]

u need to verify game files after deleting that

but yeah was worth a try

[somber hornet]

okay doing that now

[somber hornet]

same error

[digital widget]

guys I bought the game on steam

and it just works in proton experimental too

on first launch... no kidding

[digital widget]

me too man... me too

[somber hornet]

Fuck me then ig

[potent meadow]

nah Fuck eac

😄

[somber hornet]

I could try deleting the pfx folder before using experimental. First, Imma reinstall the game tho

[potent meadow]

Ye same here

Its just heroic That needs a custom runner now

[somber hornet]

fuck it I give up. I'll just play on epic

[potent meadow]

for now. u wil lbe restless and unsatysfied

😛

j/k .. eac is weird its not just linux

[digital widget]

dude lets try creatibg another folder for steam library

and install the game in the other folder
