Newer hotfix patch fixed the issue

I had to use Proton GE for the game to boot up versus using experimental like I usually do

Marche très bien le bug de la maj du 03/04/2025 sur l'anticheat (Tavern.exe) semble résolu ! :)

LD_PRELOAD="" STEAMDECK=1 %command%
Contacted Ironmace directly informing them that all Linux compatibility was broken and had a conversation back and forth. Info was provided as requested and today this morning I was informed that the game would have a patch released that would solve the Linux launch problems.
Dark and Darker now works again out of the box (07/04/2025) using Proton and some launch options. Additionally another bug that made the game hard to launch was squashed as well.

Ne se lance plus depuis la maj du 03/04/2025
Marchait parfaitement jusque là :(

3 April 2025 Build 17966455 Game is Borked. On Launch steam shows running but no window opens. Eventually returns error code 16.
I only recently started playing and prior to this the game ran perfectly on proton 8.0-5. as of April 3rd the game would not launch. Kudos to Mr. Jericho here and on a reddit thread that helped point out what was most likely broken. At this time we are only able to wait on the devs.
Latest update killed launching the game on Ubuntu Noble / 24.04 April 2025 update

Broken on 04/03/2025, was running and playable before 04/03/2025
STEAMDECK=1 gamemoderun %command%
Does not run currently due to a game or anti-cheat update. Not happy with the devs for the constant back and forth on game working vs game not working when I would like to enjoy the game and support their work.
Tried forcing proton Experimental and using proton GE 9-26 and 9-27 used various launch options with proton 5.13-6 and was still unable to launch it (it was running but the game won't launch) but did receive error code 16

Game broke yet again with the "3 April 2025 -- 08:05:08 UTC" update.
LD_PRELOAD="" STEAMDECK=1 %command%
After the latest version came out the game has all but completely broke. Cannot launch on my system any longer. Tried both on my Nvidia system and AMD. Tried Steam Deck as well with no luck. Found several posts across different forums that all report the same problem and on Windows as well.

I have start the game for the 1st on Linux time yesterday, playing during a good hour with a least 10% more perf than windows. But sadly today after a unexpected patch the game won't start again.
That seams to be the case at each update.

Any proton version except 8.0-5 fails to launch.

LD_PRELOAD="" STEAMDECK=1 %command%
Had to mess with different combinations of versions and launch options before it started working.

STEAMDECK=1 gamemoderun %command% -ngxdisableota -DX11
running game on patch #79 results with game not starting and error code 21 is shown in system dialog menu. Had to just switch to proton 8.0-5 and it helped.

The game worked as expected after I set the launch options and used GE. I would recommend not touching anything until the game starts, tho.

All steam proton versions don't seem to work, I even tried experimental bleeding edge.

Could not get to run on Debian12

STEAMDECK=1 gamemoderun %command% -ngxdisableota
Inconsistent lag in Stash and Merchant screens, smooth gameplay though, in fact I perceive better performance on exact same hardware on this Linux setup than I did under Windows.
Game did not run without tinkering. Initially I could not get the game to load, it would just be a black screen, spin one CPU core at 100% and never load. Then I installed Lutris, switched Steam to use Proton Experimental and adjusted my launch options. Then the game ran beautifully on max graphics settings. I've made it to level 8 with no bugs or glitches. I read others posting that team play performance was not good but I have only played solo.
I really like this game and I'm glad with minor effort I got it running on Linux.

Solo play is fine, it's duos and trios where you have about 30-40 FPS consistently, UNLESS, you're party members perish and leave or you go into spectator mode because you all died.
GE-Proton9-23 should be releasing hopefully soon. Maybe then it'll address the problems with FPS drops in duos and trios.

Working out of the box
I just tried it bc I was bored, I saw others reported that tha game is not working after an update and I gave a shot and played few a matches with a friend. (Probably patched the december crash bug, tested on 12-22-2024)

STEAMDECK=1 gamemoderun %command% -ngxdisableota
I'm surprised. I thought the sorcer patch introduced some form of change to their in house anti-cheat and that would be the end for us. The devs on discord actually responded when asked about this and fixed it the following patch.

Lo tengo por heroic y lo añado a Steam, después del Wipe de la season 5 me estaba fallando al terminar el "Conecting" y veo que es un error generalizado. Pero lo que he hecho ha sido forzar la actualización en Heroic y volver a iniciarlo como lo hacía antes.
Añadir desde Heroic a Steam e iniciarlo desde Steam como juego externo. Pongo el proton 8.0 en Heroic.que es el más estable que conozco para este juego.

Previous update broke the game, it was something related to audio issues. With Early Access Hotfix #74 the game is back and running again.
LD_PRELOAD="" STEAMDECK=1 %command%
If you want to copy my launch settings keep in mind gamemoderun or similar is recommended to disable desktop composition for performance. I just have it completely disabled on this PC for convenience.
Launch option: LD_PRELOAD="" - fixxed some weird lag bomb in previous update, not sure if it's still necessary.

After the new patch game crashes every time it tries to connect to the server on startup.
Previously I used GE-Proton 9.7 and it was all great, 30 hours of gameplay 0 issues. Now not a single proton version works. Tried versions from 7 to 9.21, but no luck. I tried proton experimental, but no luck.
Verifying file integrity didn't fix this issue as well.

Early Access Season #5 broke all Linux support.
STEAMDECK=1 gamemoderun %command%
Since the latest season dropped (18/12/2024) all Linux support has now stopped working. The game will launch perfectly fine but once you get to the part where the game client has to connect to the Dark and Darker servers you will instantly crash to desktop.
I've tried every combination of proton version and launch commands I personally know. ProtonGE, Proton9,8,7 and so on. With and without launch commands. I've tried setting up a bottle but no luck.
Game is from the looks of it currently completely broken.

New Sorcerer patch borked on Linux
Crashes in "Connecting" window after starting the game

Don't work with MX Linux 23.4 and Linux Mint 22. I can start the game and see the main menu, but all online servers are unavailable.
The online game server is always down. I also have this problem with Dead by Daylight and Hunt Showdown.

For some reason the game stops launching after a few successful startups and game sessions.
This was the case for the previous update (Hotfix #72) and is the case for this update (Hotfix #73). The game started a few times for me on the previous update and then stopped working. After a patch it started working correctly again, I was able to launch it 2 or 3 times throughout several hours, but then after half a day it stopped working again. I tried different proton versions, GE and not GE, they all don't change anything. I'm not sure what is the cause of that. Verifying integrity of game files doesn't help either.

Stability feels better than on Windows on the older maps, completely playable VOIP and all so still going to be incredibly fun.

Glass/Transparent Bottles (Potions) will be floating liquid, not a big problem.
The "Ruins" map has severely poor performance compared to any other map (Likely just an optimization issue and not Proton), you will get normal performance after taking a red stair to "Crypt" or playing on other maps.
Wayland Drivers seem to work with no issues (as well as better mouse capture on launch i.e clicking on the "OK" button at the start), if you prefer running that over XWayland.

Lots of stutters; low fps in general compared to other games

gamemoderun %command%
The first startup was very slow. There was a black screen for a good minute or two before I reached the loading screen, that also took a while. After that everything was good. The game starts up quick, runs good.

Game runs smooth and with 9-19 seems it went from 80 fps max 60 lows on max settings to 100 fps max 75 lows.
STEAMDECK=1 gamemoderun %command% -ngxdisableota
Was stuck playing with proton 9-2 / 9.7 GE before but seems 9-19 GE proton made it work again without the tavern error.
The tavern breaks without proton-ge, so until the devs fix this bug, it is only playable on 9-7
