When starting, it shows loading screen, and then it's just a black screen.

Protontricks to install DirectPlay for Multiplayer
Flashing screen when running open source Nvidia drivers, using proprietary drivers fixed it.
Alt + Tab or others methods to change windows make the game unplayable
=> Protontricks
=> Protontricks

Pretty much everything works as intended, you just cant alt tab. If you attempt to do so to, lets say, message someone on discord real quick and then go back to the game, you'll be met with a black screen with the audio still playing.
freeze/crash at alt-tab

Alt tabbing gives black screen (the game, not whole) and sound plays but cant play the game itself
Dont alt tab

Use protontricks to install DirectPlay dll for multiplayer. Also recomend virtual dekstop (via winecfg) because the game goes black when you alt tab out.
as mentioned alt tabbing out of the game resoults in a black screen
as mentioned DirectPlay is needed. (Also on Windows Clients! -> Install via Windows-Features)
Old classic working great.
Runs perfectly fine without any tinkering

Works great and smoothly on the steamdeck. You need to choose a community layout for the best experience, because this game was made for keyboard / mouse.

Singleplayer is working without any problems / stability issues

no sound at all
everythings works except sound
Installed, launched, worked fine, no tweaking needed.

Tinkering is required for LAN Multiplayer to work.
You need to enable DirectPlay for the Multiplayer menu to work. You can do this in desktop mode using Protontricks.
Fantastic game. I hope Stronghold Definitive Edition will be good since Firefly Studios haven't had much luck in their last 10 years of game development.
Only works in local network or with port forwarding due to GameSpy being shutdown
Nach Alt-Tab blieb der Bildschirm schwarz.

run this 1 line:
env WINEPREFIX=~/.local/share/Steam/steamapps/compatdata/40970/pfx winecfg
# if steam is installed in a different location, change the path
This will open a window. Cancel the "mono installer" dialog.
In the window, go to the graphics tab and check the box for the "mouse capture" and "create a virtual desktop" with your screen resolution. On my system, this resulted in a blinking blue screen at startup, but enabled "Alt-Tab" functionality.
Start the game with Proton 5.0 and close it. Then, use the following command after you installed "protontricks" for your distribution:
protontricks 40970 directplay
After directplay is installed, you can change back to the default Proton version. I got permission errors, when trying to install directplay with higher Proton versions.
It works right out of the box.
Alt-Tabbing won't let you return to the game.
Perfect. Thanks to Gamescope, problems with Alt+Tab and artifacts while creating a screenshot fully disappeared. Runs better than on Windows
gamescope -e -f -- env ENABLE_VKBASALT=1 MESA_LOADER_DRIVER_OVERRIDE=zink %command%

(GOG version) Works good
Played GOG version with Proton 7.0-1.

You can even patch the game with UCP if you feel the need.
In my case i had to use winetrix to install the UCP but i think protontrix works to
I don't know why but actually its nocht playable on proton 7.0.1 so fare it looks like som system component broke it from working
Alt tabbing doesn't work might as well be bronze rated
Alt tab would mean game breaks and you can't save. Not strictly a game saving issue, but still.
Alt Tab causes the game to be blank.
Works perfectly fine!
Alt-Tabbing worked fine after enabling the virtual desktop using winecfg!

Just don't alt+tab.
Works great, just don't alt-tab
Game goes black when loses focus
Works flawlessly
Proton-6.8-GE-1
Game switches to Blackscreen after tabbing out
Fixed alt tab by enabling virtual desktop in winecfg: WINEPREFIX=
Fixed permission in prefix folder to be able to install directplay: sudo chmod 766
Installed directplay to enable multiplayer WINEPREFIX=
proton version: 6.3-2
Fixed alt tab by enabling virtual desktop in winecfg: WINEPREFIX=
Fixed permission in prefix folder to be able to install directplay: sudo chmod 766
Installed directplay WINEPREFIX=
Just install and play.
Runs perfectly out of the box
Sometimes I had to schange the resolution to show everything properly in fullscreen
It's only working with proton 5.0-10
Alt-Tab does not work. When game window loses focus all is lost. Game does not have autosave, so requires manual saving to not lose too much progress.
Winetricks did not help me resolve this.
1st step: Install wine. Type WINEPREFIX=/path to your steamapps/steamapps/compatdata/40970/pfx/ winecfg in terminal the like comrades advised in the comments below.
2nd step: Graphics tab > check "capture the mouse" and "emulate a virtual desktop". You may need that to freely switch windows by pressing alt+tab.
3d step: install protontricks (pip install protontricks). Install directplay (protontricks 40970 directplay). That is multiplayer fix.
