I want to improve the quality of the tabs on the left (army, inventory, abilities) and the quality of the pupil in the spellbook.
I increased the resolution by a factor of two and noted the new size in the xdb file. But in the end, this led to incorrect display, much larger than the actual size in the interface.
Post some improved texture here (army, inventory, or abilities) and a screenshot of what's wrong with yours, I want to check it out myself.
