Change menu language in Red Dead Redemption 2
How can I set my menu language to english? I don't see any option ingame for changing the language. The language of the Rockstar launcher is already set to English. Adding the launcher argument '-uilanguage "american"' or '-uilanguage "english"' did not work, either.
Do I have to change the language of Windows?
According to this source, the game language can be changed in the Rockstar Launcher settings. Select settings and change the launcher language to your preferred language. You then need to restart the launcher and you may need to restart multiple times -- alternating between the current language and your preferred language. You should then be able to run the game with the correct language for the UI/subtitles.
If all this fails, you can also change the language set on your PC to the desired language and restart the launcher and game.
