Other commenter suggested using GoG version with an older version of proton, this worked for me with the heroic games launcher. I'm actually using Proton 7.0.0 because I happened to have it installed but seems to be working just fine. Using a modern wine version worked but was extremely slow, thankfully reverting to the older proton version made it much snappier and allowed me to switch windows without shrinking the resolution.

Fun trick: alt tab for a few hours and come back. A bunch of queued up sounds will play at once. 😨
Fullscreen crashes on screen transition, borderless/windowed is fine
Once you've installed UAP, go into "Arcanum/HighRes" and open "config.ini". There, set the width and height appropriately and change the windowed line to "Windowed = 1." Then, run "_install.bat" with your choice of compatibility layer. After you do this you should be good to go - but once the game is open you will want to use whatever key combination your window manager uses to enable borderless mode if you set the resolution to your monitor's own.
Proton versions later than the one used fail to load the game after the second post-character creation FMV.

Works better on Ubuntu 24.04 than on Windows 11
There is a video recording to showcase and give an idea how it works here: https://www.youtube.com/watch?v=AxipaTh11vM

I am playing the GOG version, which worked out of the box with Proton 7.01 on both Heroic and Steam for the vanillia game. The GOG version has some fixes already added to it (It's what they do) so if you have that version go for it, works great.
But I saw on here there was a Multiverse version that adds a bunch of cool mods (like widescreen) and some add-on stories, cheats and even more fixes and it also works just fine with Proton 7.01 on Heroic and Steam.
There is no "Arcanum" Sub-Folder to delete, just run the exe file through Bottles and I made it a sub-folder so it kept my orginial install. You only have to run the config.exe once unless you always want the launcher to start, if not just set the path back to arcanum.exe after setting it up.
Any Proton past 7.01 does not work, it will crash on the first map screen after a long load screen.

Game got stuck after alt-tabbing
Infinite loading with newer proton versions
- Use older Proton version(6 or 7 worked for me). New versions caused stuck in infinite loading screen (clock).
- Install UAP and HighRes patch. It is a mandatory mod anyway that improves game experience a lot. Need wine to install. https://steamcommunity.com/sharedfiles/filedetails/?id=3198444292
- You need to set config.ini of HighRes to your screens resolution to avoid alt-tab issues. Run _install.bat with wine after you change conifg.ini from the same folder.

WINEDLLOVERRIDES="ddraw.dll=n,b" %command%
I did try with UAP 2.0.2 w/ HighRes but it made game unplayable (ridiculously long loading, cursor issues). Cursor jitter if your session is Wayland - you may need to create a file like
~/.config/environment.d/50-kwin-sw.conf
and put:
KWIN_FORCE_SW_CURSOR=1
Funny tho I had the issue playing Arcanum on windows as well w/o HighRes. It looks like Wine's ddraw.dll is essential to be able to play original version.
Works ootb.

WINEDLLOVERRIDES="ddraw.dll=n,b" %command%
Extreme slowdowns are common under Proton/Linux. To solve them, right click in the game from the Steam library, then open "properties", and in "launch options" add the following:
WINEDLLOVERRIDES="ddraw.dll=n,b" %command%
Should work for the standard resolution. If you're using a wide screen monitor, the full screen mode might fail to cover the whole area, but slowdowns will be gone and the game will be playable with no other problems.
[Do it in the files themselves]
Do what this person did: https://steamcommunity.com/app/500810/discussions/0/343785380899864700/
Do these steps to remove lag from the game https://steamcommunity.com/app/500810/discussions/0/343785380899864700/
Input lag is a second or two by default.
-no3d -doublebuffer
fixed by uap
- atempt 1: on default proton version game was very laggy, changed to proton version 5, it fixed lags, but graphical glitches made it unplayapble, uap crashed with no error message
- atempt 2[successful]: uninstalled, removed leftowers in steamapps directory, installed again, added all permissions to Unofficial Arcanum Patch .exe file + execute permission, readded it to steam with default proton, this time it managed to run created a link to arcanum directory in home as uap doesn't see steam directory and pointed uap to that link, this time it managed to install
with patch installed both lags and glitches are gone

"-no3d -doublebuffer"
You either got two options. The first if you want the most original experience is to set launch options as "-no3d -doublebuffer" which result in the game playing normally with no lag. Or if you wanna get the better graphics option, you get the unofficial arcanum patch, but beware that the high res patch in itself deletes the multiplayer option, if you don't use it the game will be pretty much unplayable unless you do the other (first detailed) workaround.
Windowed mode is pretty much non-existent unless you start it on a virtual desktop on proton
input is laggy as hell if you dont change settings
The game is buggy and laggy if you not change launch options or install the patch
Installed UAP
Sometimes alt-tabbing results in a black screen. Hitting ESC and/or alt-tabbing again fixes this
Installed the Unofficial Arcanum Patch
Here is the fandom page for modding Arcanum: https://arcanum.fandom.com/wiki/Modding_and_Patches#Newest_Method_.28as_of_2020-09-17.29
Using the Launch Options "-no3d -doublebuffer" is neccesarry, as well as the mod "Arcanum Multiverse Edition".
If played with HiRes Patch, after Alt+Tab, the game is displaced (only half of the screen)
Arcanum Multiverse Edition (AME):
Delete game folder Arcanum “…/steamapps/common/Arcanum/Arcanum”

Proton-6.1-GE-2 GloriousEggroll
Scaling is stretched due to my widescreen, but that can be fixed with mods.

5.8-GE-2-MF GloriousEggroll
Loosely followed this guide: https://arcanum.fandom.com/wiki/Modding_and_Patches
My experience was:
- Run game once to set up prefix. Quit game.
- export WINEPREFIX=[path to SteamLibrary]/steamapps/compatdata/500810/pfx
- winetricks win7
- Download the required mods (*) listed on above site to a temp directory; cd to this directory.
- install each mod in turn using wine (or 'wine start' for batch files). All content should go in the [path to SteamLibrary]/steamapps/common/Arcanum/Arcanum directory, except as shown in Readme files.
- in the Arcanum/HighRes directory, edit the config.ini file and change the entries to suit your desktop resolution.
- Restart game through Steam and profit!
- The mods I installed were: Unofficial Arcanum Patch 2.0 (from here: http://terra-arcanum.com/drog/uap.html#download), High-quality Town Maps, High Resolution Patch 1.5, High-quality Music, ArcanumXNoNoise.dat, Arcanum Level Cap Changer.

Installed fine until the main game menu where the mouse cursor is slow
After follow this guide (http://roman-yagodin.github.io/guide/2019/11/12/arcanum-proton) by words and I've played it for a couple of hours already and everything works as far as I know.


Install game through steam-native-runtime. Proton 4.2-4.
In a Terminal run :-
"WINEPREFIX=$HOME/.steam/steam/steamapps/compatdata/500810/pfx/ winecfg"
Under the "Graphics" Tab tick/check "Emulate a virtual desktop" 800 x 600.
The game was now playable, with low res, the fix is easy.
Download the High Res patch from here :-( https://arcanum.fandom.com/wiki/Modding_and_Patches )
Unzip, copy Highres folder to:- $HOME/.steam/steam/steamapps/common/Arcanum/Arcanum/
open a Terminal inside Highres folder and run:- winefile
change Res' in the "config.ini" file and save, then install the "install.bat" done.
I am playing at 1920x1200 no issues. You can of course play at any Res' full screen now
simply run:- "WINEPREFIX=$HOME/.steam/steam/steamapps/compatdata/500810/pfx/ winecfg" again
and un-tick/check "Emulate a virtual desktop" after setting your chosen Res' in the "config.ini" file.


Working fine, but with major lag when doing anything and very long loading times.


Works with ddraw override, weird issues sometimes though. Alt-tabbing in/out causes a redraw delay (black screen for short periods), and sometimes esc doesn't open the menu. One thing to note, the Proton auto-detect thing is inaccurate. My system is Ubuntu 18.04 with nvidia 418 driver.


Unplayable. No cursor on main menu


no cursor on main menu (with dgvoodoo dll's)



Works fine so far, but require to override ddraw to wine version.


Copy dgvoodoo dlls found here: http://dege.fw.hu/temp/dgVoodooWIP53.zip to Arcanum/Arcanum/ then set winecfg ddraw override to native on the prefix. this translates dx7 to dx11, which then works with dxvk. game works flawlessly afterwards


Takes too long to load main menu, about 10 minutes to load game. Major issues with textures (many artifacts, invisible people, overlapping dialogs). Installing HD patch does not fix anything.



No cursor in the menu, or just the redraw problem worsened.



Performance/Can't start the game



Game starts, but menu is extremely laggy. Gets stuck in a loading screen upon trying to go ingame.



The menu redraws slowly, the map haven't finished loading in reasonable time. Worked perfectly in Wine with the Arcanum Multiverse patchset.
