Works reasonably well after heavy tinkering. The game itself crashes on Windows too, so there's not much you can do about that
DXVK_FRAME_RATE=75 %command%
engine.ini - Disable fullscreen and increase windowed resolution (fixes alt tab crash), change near and far clip plane, set FPS limit to a very high value (ingame limiter has bad frametimes so I used DXVK's framerate limiter instead) A big portion of the game is uncompiled C code, which allows you to change and mod the game yourself with little effort. What was mostly essential for me was to change the camera FOV at sea, officer salary and enable cheats/dev mode
Winetricks: change Windows version from 7 to 10 or below and try and see if that lowers the crashing frequency
Sometimes map textures would go missing, this got fixed either by lowering Proton/wine version or by using OpenGL instead of DXVK
Game crashes if you alt tab out of fullscreen. Change to windowed mode by tweaking with engine.ini and set the window resolution, or keep it at fullscreen but launch wine/proton under a virtual window
Very rarely the input would stop fully working until I either disabled KDE Plasma's compositor or restarted the game
Proton 7 and higher has awful framerates on some islands and cities, while Proton 6 and below don't have that problem
Ingame framerate limiter has bad frametimes. Set the framerate limit on engine.ini to something as high as 150 or 300 or use DXVK or libstrangle framerate limiters
Crashes very frequently. Lower this crash rate by lowering proton version and setting the game as Windows 10 or below 7 on winetricks/protontricks. Disabling DXVK and Fsync seem to also help
Wine 7.15 and Wine/Proton versions 5 and below crash at sea, so use Wine/Proton 6
Video playback does not work. I fixed this by launching the game on Lutris and enabling Lutris runtime
In a nutshell: change engine.ini, disable fullscreen or emulate a window, change the game's code to your liking as it is mostly uncompiled, lower Proton version to 6, change Windows version to 10 or below 7 in winetricks/protontricks, optionally disable DXVK and Fsync to see if the game crashes less, try using dgvoodoo2 (didn't do anything for me), use Lutris runtime to fix video playback
Works very well except for the crashes. This game needs mostly the same tweaking as it would need on Windows

Very very rarely you might not see textures on a character or the ground (most likely fixed by using OpenGL or dgvoodoo2)
Alt tabbing from fullscreen crashes the game (happens on Windows too). Disable fullscreen and set the window resolution in engine.ini
Extremely rare chance of crashing during saving and corrupting that save point. Happens on Windows too
Performance is slightly worse than on windows. I didn't manage to find a way to fix this, and it's not a hardware problem either
Crashes at an annoying frequency when loading a different scene/place/room, more than on Windows Proton's DXVK works, but DXVK on regular wine doesn't
It unfortunately doesn't run perfectly out of the box, but with dgVoodoo and Proton-GE it runs great. Enjoy :)

Using Proton-GE seems to fix the intro videos, which weren't playing properly for me. You probably don't need an as recent version as I tried, but it's the version I had on hand.
Installed dgVoodoo by placing its 32-bit DLLs in the game directory, and set the launch options to WINEDLLOVERRIDES="ddraw=n,b;d3d9=n,b;d3d8=n,b" %command%. Gamemode and Mangohud both work with this game, in case you want to rely on those tools.
I don't think overriding d3d9/d3d8 is strictly necessary as the game seems to use directdraw, but I wanted to play it safe and fully rely on dgVoodoo.
The game does boot up and gets ingame without dgVoodoo, but it showed very weird frame doubling issues and it wasn't smooth, with the game even showing previous frames sort of blink back in view, it's not pleasant. dgVoodoo seems to fix everything, and the game ran very consistently at a matched framerate with my monitor's refresh rate.
