Operating System: Windows 10 Pro (Insider Build #18963)
Game: Queen's Wish: The Conqueror
Vendor: Steam
Graphics: GTX 970, Nvidia 440.23 drivers
The game startup shows the configuration menu for monitor resolution & graphics quality. Any selection (I tried both 2560x1080 and 1900x1080), and all 3 graphics qualities results in a whitescreen after pressing "OK". Window and no-window mode also made no difference.
I tried verifying the game contents w/Steam, as well as uninstalling, re-installing, and rebooting windows. DXDiag output.
