Today 2.01 got released. It (somehwat) fixes the blurry font on my 1440p screen, however not before I actually started the game, the initial menus remain blurry.
Now that I see the UI for the first time how's it's meant to be, I still think the font rendering of their engine is awful. Maybe The font itself is not ideal.
I really wish the UI wouldn't upscale on higher resolutions. I can somewhat handle the blurry icons, but the blurry text is horrible to read, esp. in a game that's all about reading dialogue.
