Proton, Linux and empty launcher window
I must confess that Black Desert Online (BDO) runs better on my Ryzen 5 5600 and GTX 1060 PC (with more stable FPS and no sudden crashes, provided the network is stable) than it did on Windows 11. When installing the non-Steam client via Lutris, you can use practically any Proton version. However, with most of them, you will see a black or white launcher after installation. As I found out (thanks to a helpful tip from someone), this can be fixed by locating the GameOptionLauncher.txt file stored in the emulated My Documents folder at /home/USER/Games/black-desert/drive_c/users/USER/My Documents/Black Desert/GameOptionLauncher.txt (find out where is your game folder and who is USER) and changing the last option to:
LauncherResourceType = 5
webvLanguage = 0
launcherRetain = 0
launcherMiniMode = 0
launcherGpu = 1
launcherOffScreen = 0
