Now the top of my paragraph is blurry, and the bottom is OK (!) I really don't know how to fix this, and would appreciate any help ! Thank you ! 回答1:

问题 I'm using SFML 1.6 to make a small game, and I need to display some text, so I use the sf::String class. The problem is, when I increase the size to 96pt, the edges appear a little blurry. When I increase the size of text in Microsoft Word though, it appears very clean and has crisp edges.
