After I launched the game I tried changing the resolution from default to 1900x1080. I chose the option and nothing happened so I figured that I might need to restart the game for the changes to take effect. I go a weird error popup, which I decided to ignore for the time being and ran the game anyway. Now the game is still in the same resolution and I can't even change it in the options anymore.
I attach screenshots showing the issue.

Does anyone know how to fix that and how to run the game in 1080p on Win10?

Hi!

If you still have this problem, try to run the game without galaxy client (simply run DMCR.exe from its folder).
This one worked for me.
