Yes this is true, same thing here, but if you use the command you can't change the option from inside the game anymore, which breaks your game anyway but just want to let everyone know.
I have an old GPU GeForce GT 750m, and there is a visual bug that happens in game all the time, the main menu is fine.
The game looks like I'm on drugs, check the image below, maybe my GPU is too weak or old to be supported, I don't know.
Deleting the CFG folder (Game>citadel>CFG) after uninstalling fixed the problem, I didn't have to use the -dx11 command though it's possible it would have fixed the problem without having to reinstall the game.
Anyway to reset the video settings before launching the game? I changed to Vulkan and now I can't launch the game at all, I get the error
AppSystemDict: Error in Connect() of interface 'RenderDeviceMgr001'!
I already disable the cloud and reinstalled the game but that didn't work. Any launch...
