Running the game under Linux with Proton-GE

Proton-GE 8.3 and later, combined with its updated protonfixes, seems to run Assetto Corsa just fine. With some tweaks you can also get Content Manager and CSP working. Most of the instructions spread about the Internet did not work for me, including downgrading to Proton 5.x.

Note that the install script that GE uses runs some commands using Proton 5.0 as of this writing, so you need that installed via Steam. You don't need it to run the game and you can delete it after you get Assetto Corsa working.

Install Assetto Corsa

Install Proton 5.0; and Proton-GE 8.3 or greater, either through ProtonUp-Qt[davidotek.github.io] or manually[github.com].
Delete WINE prefix from /path/to/SteamLibrary/steamapps/compatdata/244210 if already present, installed Mono and .NET from other Proton versions and protonfixes can cause problems with GE's protonfixes.
Close Steam if it was running, then launch it again.
Ensure the GE-Proton version you downloaded is selected in Steam > Assetto Corsa > Properties > Compatibility.
Start AC, and wait. protonfixes is installing multiple versions of .NET, I guess the shotgun approach was used since I doubt all of that is really necessary, but it does work, as AC should open, eventually. If you launch Steam from terminal before launching AC, you can see what GE is doing.

That's it. You shouldn't need to do anything else and the game should just run.

Install Content Manager

Copy Content Manager.exe to your /path/to/SteamLibrary/steamapps/common/assettocorsa directory. You can open this directory from Steam by right clicking Assetto Corsa and navigating to Properties > Installed Files > Browse...
Rename the file to Content Manger Safe.exe to disable hardware acceleration in CEF, which does not work and will give you black windows.
To launch CM instead of the vanilla launcher, set your launch options from Steam by right clicking Assetto Corsa and setting to Properties > General > Launch Options to:
c="%command%";sh -c "${c::-17}Content Manager Safe.exe'"
Create a softlink to loginusers.vdf in the WINE prefix so CM can find your Steam user information:
ln -s "$HOME/.steam/root/config/loginusers.vdf" '/path/to/SteamLibrary/steamapps/compatdata/244210/pfx/drive_c/Program Files (x86)/Steam/config/loginusers.vdf'
Launch CM and configure it.

Warnings

Do not create a shortcut when CM gives the option, it will crash WINE as it uses an unimplemented function, and will continue to crash every time you start CM. Delete the shortcut from /path/to/SteamLibrary/steamapps/compatdata/244210/pfx/drive_c/users/steamuser/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Content Manager.lnk and delete your Content Manager configuration files from /path/to/SteamLibrary/steamapps/compatdata/244210/pfx/drive_c/users/steamuser/AppData/Local/AcTools Content Manager to stop this from happening.
Do not use native Linux paths in the installer, without prefixing it with Z:. If you do, image previews and other features of CM will not work or cause CM to crash. For example, Steam Deck users should put Z:\home\deck\.steam\steam\steamapps\common\assettocorsa as the path to AC when CM asks for it.

Custom Shaders Patch

Install Protontricks[github.com].
Run this command:
protontricks 244210 winecfg
In the window that opens, navigate to the Libraries tab, and add a new Native (Windows) override for dwrite.

Note that depending on which version of CSP you are running and which features you have enabled, you may need to install additional fonts:

Download this file[files.acstuff.ru] and copy the system directory to /path/to/SteamLibrary/steamapps/common/assettocorsa/content/fonts/.
Run this command:
protontricks 244210 corefonts

Do note that CSP versions between 0.1.79-preview5 to 0.1.80-preview108 do not work under WINE. You must use a version before 0.1.79-preview5 or after 0.1.80-preview108 or else CSP will fail to load. I can confirm CSP 0.1.80-preview218 (latest preview as of this writing) does work.

Works with Proton-GE 8-11 and 1.74 on Fedora. Mate, thank you because I had come up with my own way to do this but was missing the dwrite before the CSP install and you helped me get mine running after 6 attempts.

Dead Set CHAMPION!

Now the question is why we get black boxes in CM when using above 1.75?

Unsuccessful. :<

Proton-GE 8-11 with dotnet48, d3d11 and vcrun2015 installed on top wasn't sufficient to get the game to run.

Maybe it makes a difference I am using an AMD GPU.

Edit: With 8-3, the game is stuck and there is no window to be seen.

Also, discard and ignore the guide you linked, it appears to be an unauthorised web scrape that's also out of date.

did you rename the executable? it must be Content Manager Safe to disable hardware acceleration.

I have not had any problems with two different AMD GPUs.
You don't need to install anything using the latest Proton-GE. it should just work.

@sev The intital steps is accurate if the person already has Proton 5 installed. The install hangs and says:

Fix would be to simply run AssettoCorsa with *Proton 5.0* from the Compatibility settings for the game and then switch back to GE-Proton-xx

You only need it installed, you don't need to create the prefix with it.

I'm using proton GE 8-20 and its working but i think i got a problem with Wine. CM is not showing any preview images and sometimes it crashes. Seems like Wine cant have total access of AC folder so it cant load the images, idk, help! :D

Edit: i was right, so i create a link to AC inside a folder that wine have access and fix the images problem.

I don't really understand what you mean, and I can only imagine you are somehow running the game after having installed it from Windows or something. make sure you are mounting the drive with AC on it so that your user has full permissions, as that's what Windows expects. if necessary, chmod your AC folder to your user.

chmod -R you:you /your/ac/folder

In my case and i don't no why, in content manager, all seems to work but the images does not appear.
In CM when you want to launch a race, the car image and the track image appear on the top left and you can choose another car or track. These 2 boxes don't show anything, just the image broken icon

did you install the game under Windows? or perhaps did you copy your existing CM data into the proton prefix?

I have a fresh install
Pop-OS
steam "deb"
protonup-QT
ProtonGE-8.25 (same issue with other version)

The game is install on windows too but the drive is not mount on my linux

this command doesn't work for me

c="%command%";sh -c "${c::-17}Content Manager Safe.exe'"

I have to use this one instead

/home/cyrille/.steam/debian-installation/compatibilitytools.d/GE-Proton8-25/proton waitforexitandrun /mnt/Data/SteamLibrary/steamapps/common/assettocorsa/'Content Manager Safe.exe'; echo %command%

I have some error during the launch

it should work under all bourne shells including bash, unless Valve changed the layout of the command. still works for me as well.

none of those are particularly meaningful and won't impact your experience.

I don't use Debian/derivatives but it doesn't matter much because the ProtonGE container uses a Debian image under the hood anyway. I believe this is more about file permissions/your game file structure than it is necessarily about your configuration or setup. perhaps if radz had been more eloquent we would have an answer for you.

are you perhaps using Steam native and not the Steam Ubuntu runtime? your command makes it look like you are. can you try with the runtime? I have never tried native with AC and there may be a package incompatibility that is causing issues.
