Changes zoom levels in RA so that the game can be displayed in 1:1 scale (and its multiples) on 1080p, 1440p and 4K. Also allows you to zoom out much further (depending on the map).
Tested with the September 2020 update.
Note: half of the zoom levels will look jagged, which is a side effect of the mod being compatible with multiples of 1080p, as well as 1440p.
Note2: the first few campaign missions won't allow you to zoom out very far, because the maps are tiny.
