Having gone through a load of work to get these games working perfectly under wine, I felt that I should write a (not so) quick wee guide so that others can quickly implement the workarounds and fixes required to get these games running under Proton / Wine. I did notice a seeming amount of additional ‘strangeness’ when playing the game under Linux, in terms of pathing and physics, although this is probably just Bethesda-ness.
All of the following was performed on a virtually stock version of KUbuntu 18.10, with a GTX 1080ti.
Before starting with an proton-specific tweaks, it is important to ensure you have the latest version of the drivers for your respective GPU, in the case of NVIDIA, you will need the 396.45 beta driver, and in the case of AMD, just a newish kernel, and the newest Mesa packages should be ideal. There are loads of tutorials elsewhere to do this, if you want let me know and I will link one.
Out of the box, these games work surprisingly well, for Skyrim everything is perfect except the audio, and Fallout has a similar situation, just with additional mouse issues. To begin with you will want to simply launch the game with steam, to create the necessary proton prefix.
For Fallout, to ensure the mouse functions correctly, you must first enable bBackgroundMouse=1 in your Fallout INI files. These are NOT located where you would first expect, being familiar with this game on Windows. To access these, you must navigate to:
steamapps/compatdata/[STEAM APPID]/pfx/drive_c/users/steamuser/My Documents/My Games/Fallout4,
Where STEAM APPID is the APPID for fallout 4 (377160),
From here, insert bBackgroundMouse=1 under [Controls] in Fallout4.ini, and in Fallout4Prefs.ini.
You will also likely need to keep the resolution of the game, the same as the resolution of your desktop.
Now, onto the fun part. Skyrim SE and Fallout 4 make use of a windows library called XAudio, and an audio codec called WMA, the current implementation of these audio features in wine is limited, and does not work properly in these games, luckily for us, there is a replacement in the works. FAudio, is currently being developed to fill this role, and works perfectly at the moment, however is as of now, not currently included in wine, or proton. If you do not want to wait for this to be implemented, the steps to use this are as follows:
First you must install the dependencies (there may be others, let me know if you get into issues).
You need to install wine. I am unsure of the current wine packages required, so if someone wants to correct me, feel free.
You will also need libavcodec-dev, for the WMA support.
You will also need git installed, if it isn’t already.
Finally you will need libsdl2-dev.
Next, hop on into your terminal. Make yourself a directory to work in, I like to do these sorts of things in ~/Documents/src, but that is purely preference.
Now, clone the FAudio repository using:
git clone https://github.com/FNA-XNA/FAudio.git
After a few moments the operation will be complete, and a new folder will appear in your current directory, named FAudio, use cd FAudio to select this folder and enter the following commands:
export FAUDIO_FFMPEG=1 export FAUDIO_FFMPEG_PREFIX=/usr make clean all
Now, there should be a libFAudio.so file in this directory, if there was an error, or this file is not present, let me know and i’ll try to assist.
Now we have the main library built, we need to compile the winedlls, to do this, use cd cpp to open the cpp folder.
Next, you will need to change the ’Makefile.wine’ file, to use the correct wine directory.
You can find the directory to use using:
sudo find / -name libwinecrt0.a
The wine directory will be the parent directory of the result showing /lib64/wine/
In the Makefile.wine file, change the line WINEDIR = /usr, to the directory discovered in the last step, in my case this is /opt/wine-stable and exit the file.
And wait for the process to complete. This will probably end in an error, but all the required files should be built.
cp ../libFAudio.so ./build_wine64/
To load the library into the correct folder.
Finally, we will need to actually load our libraries into the Proton folder, and FAudio provides us a handy way to do this, using the install_fake_dlls.sh script.
You will however have one final task to do, and this is to set the PROTONDIR for this script. The script has a default location which may be correct, however in my case was not. To find this directory use
sudo find / -name libwine*
And spot out the one which has a 'Proton’ in it.
You will next need to set this directory in the ./scripts/install_fake_dlls.sh script, by changing the line
export PROTONFOLDER="~/.steam/steam/compatibilitytools.d/flibitProton/dist"
To your correct directory. If the directory has a space in it, you may need to rename your proton folder for the time of the copy, as in my noobness, I don’t know how to use a space in bash!
bash ./scripts/install_fake_dlls.sh
This will probably end in an error, but as long as the error is something about build_wine32, you should be good to go.
Rename your original Proton folder if you changed it for your copy and…. phew. You should be good to go, so go enjoy, and report back with any issues you have!
PS: This is my first time doing something like this, so feel free to let me know how I could do better, and if you have any questions or run into any issues, feel free to ask!
