Running games through Steam's Proton is great. But what if there is a secondary exe or configuration application bundled with the game? How can you launch it if Steam itself only launches the game?
Simply run this command in a terminal:
cd /path/to/steam/steamapps/compatdata/20920/pfx
STEAM_COMPAT_DATA_PATH="/path/to/steam/steamapps/compatdata/20920" WINEPREFIX=$PWD \
"$HOME/.steam/root/steamapps/common/Proton 5.0/proton" run ./drive_c/path/to/custom_application.exe
Where 20920
is the game id.
First you cd
(change directory) to the proton prefix in question. If you don't have any custom steam libraries it likely will all be within your home directory. To find it easier you may run find . | grep compatdata
from ~/
and when you find it, cd
to it.
Real world example:
cd /media/michael/SSDGAMES/steam/steamapps/compatdata/20920/pfx
STEAM_COMPAT_DATA_PATH="/media/michael/SSDGAMES/steam/steamapps/compatdata/20920" WINEPREFIX=$PWD \
"/home/michael/.steam/root/steamapps/common/Proton 5.0/proton" run \
./drive_c/flawless/FlawlessWidescreen.exe
Someone in the comments below created a bash script that makes this easier: https://gist.github.com/michaelbutler/f364276f4030c5f449252f2c4d960bd2?permalink_comment_id=3921629#gistcomment-3921629
Dude, this is GREAT!
Finally maybe an option to use Proton for STALKER Lost Alpha?
However STALKER Lost Alpha is not a Steam game, I have to add it as a non steam game, is there a way to do this for non steam games as well?
I've tried to use Lutris, and while it works, the performance was horrible sadly.
