I'm trying Kingdom Come Deliverance for the first time. First it didn't start because my GPU (RTX 4070) was unsupported. Switching from Wine-GE-Proton8-9 to Wine 10.7 (staging) fixed that and the game starts.
During the intro video, I see weird codes in the subtitles all starting with @. Then in the menu everything starts with @ui_. I suspect translation texts are missing, switch to German, and indeed nothing changes.
So why are these labels missing, and how do I fix this?
