Make Fonts "Sharper"

I play on a 1920x1080 monitor, and some of the fonts look quite blurry. As if it was resized, rather than having text made for that size. It ends up being quite hard on the eyes. In the attached image, you can see how blurry the bold "Controls" text looks at the top. Versus the sharper non bold text below. That blurry text shows up in a lot of places in the game and I think the game would be improved a lot if there wasn't blurry text all around the game.
