Hi, I just switched to a high-end monitor and I’m now running the game at the highest resolution of 3840x2160. It looks amazing! However, the UI scaling in the options menu only appears to affect the skill bar and pause menu. Everything else is tiny, including the main menu UI, loading screen texts, and the cursor. With a lot of effects on the screen, the cursor is nearly invisible, making gameplay difficult.
Edit to add that dialogue screens and the skill window are scaling properly.
