I have the blurry font problem too (1440p screen, release build). Really annoying. Reducing UI scaling from 100 to 70 or 80 reduces the problem, but it is still quite a pain for my eyes. I will try running the game in 1080p (my screen might do a better upscale !), but I might as well wait for a patch to have the best possible experience with the game, as it is otherwise really cool !
