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
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
RenderHeight are what you want to change to your custom resolution. The example shown above is for a 1920x1080 resolution.
