Rocket League doesn't respect my language when added to Steam and launched from there

I have tried different methods of setting the language for the game, but I couldn't figure it out. It should be set to German, which works from within Heroic, but launching it from Steam, it doesn't respect that preference and runs in English. Could someone help me with this?

Did you found a solution? Got exactly the same

in heroic, in the game settings go to advanced > Game arguments > set the value -language=XYZ-language=XYZ replacing XYZXYZ with the 3 letters code for your desired language from that support page

Global Setting in heroic an Game argument changed to de/deu. In Desktop Mode it works.In Game Mode it is eng again. Have to say it is on steam deck. If i launch the game through steam on desktop mode it works too. Only on deck mode it will use english.

can you share a game log with the argument set?

then-purple•12/30/23, 8:28 PM

I will try to Share it, have too look how to log it in game mode

then-purple•12/30/23, 8:31 PM

Need a few minutes

awake-maroon•12/30/23, 8:39 PM

you can run in game mode then go back to desktop mode and that should be log you see in settings > logs > rocket league

then-purple•12/30/23, 8:46 PM

I will try Environment Variables now with LANG=de_DE.UTF-8

then-purple•12/30/23, 8:50 PM

Perhaps it will do

then-purple•12/30/23, 8:53 PM

This works, thx for your Support

awake-maroon•12/30/23, 9:00 PM

you are setting the preferred languagepreferred language configuration, you are not adding a -language=DEU-language=DEU Game Argument

awake-maroon•12/30/23, 9:01 PM

do exactly this:

game settings
advanced
in Game Arguments put -language=DEU-language=DEU
clear the Prefered languagePrefered language setting

then-purple•12/30/23, 9:10 PM

I will try it also

awake-maroon•12/30/23, 9:11 PM

if it still doesn't work share a new log

awake-maroon•12/30/23, 9:11 PM

(share a game log, not a heroic log though)

then-purple•12/30/23, 9:11 PM

IEnvironment Variables with LANG=de_DE.UTF-8 works

then-purple•12/30/23, 9:12 PM

I try now your Suggestion also

awake-maroon•12/30/23, 9:13 PM

the option with the game argument is the official way to do that based on the epic support, the other one might works but it's not the best option since it's not the documented way

then-purple•12/30/23, 9:14 PM

Ok i give it a try

then-purple•12/30/23, 9:15 PM

Works also thx a lot, But where was it documented? Do you have a link for me?

then-purple•12/30/23, 9:16 PM

You mean the reference by epic?

awake-maroon•12/30/23, 9:18 PM

yes, the epic link

then-purple•12/30/23, 9:18 PM

I dont know why i missed that

then-purple•12/30/23, 9:19 PM

I thought i tried it

awake-maroon•12/30/23, 9:20 PM

it's kinda hard to find though, they didn't do a good job with that (it should just be a game configuration, but I guess they were lazy haha)

then-purple•12/30/23, 9:20 PM

True
