People have made posts about this before from a few years ago, but I feel like I need to make another. Scaling in DoW 1 and 2 is pretty awful. Playing at 1440p, the mouse cursor is a bit too small and gets easily lost in all the on-screen clutter. 4K makes matters even worse, where the mouse cursor is barely even legible on screen. On top of this, the menu text size gets extremely hard to read, and you can't even see blips on the mini-map at 4K. If you hear an audio que that you're under attack, and look at the minimap to see from where, you're screwed because nothing shows up on the minimap. If I recall correctly, the hud in DoW 2 also doesn't scale very well, making it harder to read.
We really need to have some official updates that fix these issues, as finding fixes via Google doesn't produce many results.
