Hello!
I had this issue with the graphics being blurry in general. The text was fine, but the game textures were all fuzzy and annoying even in max graphic settings.
Today I wanna show you my easy fix!
Here’s how it works:
While in game, please go into Settings → Visuals → Scroll down to Dynamic Resolution Scaling → Turn it off
Another thing to consider checking is your resolution, mine is personally at Fullscreen → 1920 x 1080. (This can also be found in Settings - Visuals)
I hope this will help you!
