In Civilization V, there is a file in the user documents that you can change to set a custom resolution, but the file no longer exists in Civilization VI. Is there a way I can set a custom resolution in Civilization VI?

The file in which you can change your resolution still exists, just under a different name.

Documents > My Games > Sid Meier's Civilization VI > AppOptions.txt

After opening that file in a text editor, scroll to the [Video] section, and find the RenderWidth and RenderHeight variables. That part of the file will look like this:

;Render width in pixels.
RenderWidth 1920

;Render height in pixels.
RenderHeight 1080

The numbers that come after RenderWidth and RenderHeight are what you want to change to your custom resolution. The example shown above is for a 1920x1080 resolution.

  • When installed on linux through steam running the windows version with ProtonGE, I found the AppOptions-file here: ~/.local/share/Steam/steamapps/compatdata/289070/pfx/drive_c/users/steamuser/AppData/Local/Firaxis Games/Sid Meier's Civilization VI/AppOptions.txt Note the 289070/ folder in the steamapps/compatdata/ directory, as far as I saw there seems to be one such virtual virtual windows disk per game besides the install files. I saw no pattern to the naming, so might be that it could change with updates, but I doubt it as it would break the players saved preferences over time.
