Steam play with non steam games


Has anyone managed to run a non steam game with steam play on NixOS yet? I tried a Windows only game I had bought on GOG with no luck. Haven’t had a chance to dig in yet to figure out the issue, but was curious if anyone had any success yet?


I have run the Windows version of Sonic Mania using Steam Play on NixOS. Worked great.


I got the GoG version of No Man’s Sky to work perfectly with this:

export STEAM_COMPAT_DATA_PATH=~/.steam/steam/steamapps/compatdata/
cd ~/.steam/steam/steamapps/common/Proton\ 3.7
steam-run ./proton run ~/Downloads/setup_no_mans_sky_44233_main_(25842).exe
steam-run ./proton run ~/.local/share/Steam/steamapps/compatdata/pfx/drive_c/GOG\ Games/No\ Man\'s\ Sky/Binaries/NMS.exe

No luck adding it to the steam launcher yet, but just made a script that does that for me.
