I got the game with the X-mas sale! Thanks for that deal, very nice. It had already been on my wishlist for quite a while.
I am trying to run the game on a 43" 4K monitor. The maps are vector graphics, so that shouldn't be too much of a problem, and I prevent scaling to keep the text dialogs intact.
It effectively gives me a really big desktop space to work with in CO2, however there is one big problem:
The biggest problem is that all zoom scales work EXCEPT for the most zoomed-in scale. This will tear the map image apart and units, orders and crossing icons are keeping their distance in relation from their unit, but don't scale properly anymore on the map.
The map itself is also skewed and broken up with big grey rectangles. Scrolling the map doesn't work anymore either at this zoom level.
Apart from this I haven't experienced any other issues yet, but I would really appreciate a fix for the highest zoom level.
All the best and happy holidays for everyone!
