Steam release of the game
Played some hours and not noticed issues within the game play
What does not
Game startup in black screen
DX11 is not available
1. The mentioned issue with the black screen. It was required to copy the DX dlls. See Howto below in order to fix
2. Installation of recent DXVK to avoid low FPS and graphical artifacts.
What was not tested
Everything within a few hours of playtime seems to be okay
By just using wine the game is basically starting with workarrounds but does have an extremly poor performance (15-20FPS) and lots of graphical artifacts. By using DXVK with latest wine and vulkan, it is working very nice with nearly stable 60 FPS. I don't have a windows system as reference, but the loading time between scenes seems sometimes slower than I might expect them. However, they are not blocking the game and I would call it overall absolutely playable. Thus there is a lot of manual work required as workarounds, I would give it max a silver rating at the moment.

Black screen issue
If your game starts into a black screen, go to the game's folder and copy over the DLLs (or override them) d3dcompiler_46.dll and d3dcompiler_47.dll:
- Source: drive_c/Program Files/Steam/steamapps/common/KingdomComeDeliverance/Bin/Win64Shared/
- Destination: drive_c/Program Files/Steam/steamapps/common/KingdomComeDeliverance/Bin/Win64/
If you see floating graphical artifacts in the game, they most likely come from water bodys anywhere. Set your water quality in the advanced graphics to at least "Very High", this will make it disappear.
Poor performance, low FPS
For now you should stick with the latest wine-staging (at the time writing this is 2.21), as non-staging gives very poor performance even on good machines (currently only nvidia tested). Hopefully a new maintainer for staging is soon to be found, as the staging patches drastically increase performance for KC:D.
Most likely the path to your "Windows Documents folder" just changed in your WINE configuration. Open winecfg in your KC:D wine prefix and double-check, if you set a Documents folder. I set mine simply to my ~/Documents, which is a convenient option if you want to have fast access to files like your savegames or your player's profile (settings and stuff). Helpful pic
