Quoting: Comandante ÑoñardoThere is not a config Proton tab or something like that...

SteamLibrary/steamapps/compatdata

Each proton game should have a folder named with the steam appid, they are the wine prefix's for the games. You should be able to modify them in order to apply custom fixes for games. What I'm wondering is what happens if you verify the game files, does it overwrite your changes. What would be great is if you could save custom prefix settings in steam like you do with save games so you can apply your customization's on other machines through steam.

I found the folder... what I need to know is how to manage the behaviour of Proton per game ( make it act as winXP or Win7) or configure the render per game: Vulkan this game, OpenGL this other..

I have these glitches in Still Life 1 and 2 and I don't know why.. I think prefixes must be tweaked by hand.

The idea of proton is: you click, the game just works.
If it is not the case, you can open an issue here:

Yesterday I tried to tweak Proton for Darksiders game.
Darksiders needs devenum, windows media player and quartz.
I did:
WINEPREFIX='/mnt/dd2/Steam/steamapps/compatdata/50620/pfx' winecfg
and I can see the Proton dll overrides...
you can try this too:
WINEPREFIX='/mnt/dd2/Steam/steamapps/compatdata/50620/pfx' winetricks

The issues with the Still Life games seem like an upstream bug. I don't think any amount of configuration will help here.

Winetricks works fine.

BTW, the default prefix path is "$HOME/.steam/steam/SteamApps/compatdata/<APPID>/pfx".

What is the console command if I want to install or uninstall an app or perform a Regedit?

For example:

$ WINEPREFIX="$HOME/USERNA_PROFILE_NAME/.steam/steam/SteamApps/compatdata/<APPID>/pfx" wine regedit

where I have to open the console?
I ask this because I type:
WINEPREFIX="$HOME/.steam/steam/SteamApps/compatdata/203730/pfx" winecfg
The game is Q.U.B.E

I got this error:
wine: chdir to /home/comandante/.steam/steam/SteamApps/compatdata/203730/pfx

1) you have to launch the game one time for Steam to create the Proton folder in compdata folder
2) if $HOME does not work, did you try with true folder path?
3) are you sure compdata folder are stored at "$HOME/.steam/steam/SteamApps/compatdata/?

1. I did
2. What do you mean with true folder path?

3. Yes.

Try without uppercase:
$HOME/.steam/steam/steamapps/common/
