enlace simbolico de $HOME/.steam/root/userdata a donde tengo instalado el juego /SteamLibtary-------> ejemplo :
ln -s "$HOME/.steam/root/userdata" /run/media/manuel/almacen/SteamLibrary/steamapps/compatdata/754530/pfx/drive_c/Program\ Files\ (x86)/Steam/

problem of windiows management makes it very user unfriendly, unless the pop out window issue can be solved.
as indicated by Mars Rover, need to do the following: cd /home/USERNAME/.steam/debian-installation/steamapps/compatdata/754530/pfx/drive_c/Program Files (x86)/Steam
open terminal and type:
ln -s /home/USERNAME/.steam/steam/userdata userdata
I still have some small issues:
- minor: an intro video windows that stays around, but i can get rid of it after a while -minor: the menu screen is not full screen and partly hidden (i've tried pseudo and full screen),but once i launch (with keyboard !) a training/ single mission, everything turns to normal :)
-i've disabled steam imput as found by Mars Rover
-The game now takes imput from joystick in the control/ axis menu: It's a bit tricky since the popup windows actually pops "down" under the main screen: i needed to set axis blind : the solution is to press change, set the key (for example fire button of joystick, then press enter from num pad), otherwise, the Alt Key will invite itself.
- the pop out issue makes it almost impossible to change the airplane in free flight missions: need to make Alt tab several times, but i did not really figure out how to select the plane (succeded only once).
Overall, performance is excellent, but ruined by the graphical interface issues :( Campaign can be started, but only the 1st one out of 3.
performance seems excellent !
(Reported experimental version: 6.3-6 or Experimental)
Symlink to a) the steam userdata folder in pfx/drive_c/Program Files x86/Steam, and symlinks to all the dlls in parts/core in the game root folder.
I got my CH Pro Pedals USB to work, but only when running the game via wine outside of Steam.
I documented the fixes on github: https://github.com/coljac/cod-proton
Using Proton Experimental (wine mono 6.3) and PROTON_USE_WINED3D, the game works and performance seems acceptable.
Couldn't get past menu without this.
A symlink seemed to be required as follows: ln -s $HOME/.steam/root/userdata /path/to/steam/steamapps/compatdata/754530/pfx/drive_c/Program Files (x86)/Steam/userdata
Using CH Pro Pedals, not detected. Joystick works.
Won't launch - nothing visible. Proton 6.5-3 and Experimental both.
Does not run in Proton 6.3 or Proton Experimental.
It does not run
Can reach menu, with graphic glitches
The game need for now heavy work to arrive there :
- With vanilla proton, dll in part/core are not loaded, linking them in the main directory is necessary
- .Net is necessary, dotnet472 did not work for me, but dotnet461 is ok
With that, the game is loading and you can see the loading screen. Next it crashes on a video (ASF format) unreadable by GStreamer. Installing wmp11 with protontricks allowed me to reach the menu.
For now I have heavy graphical glitches, I keep digging.
Refused to start, no error message or notification
