No, I didnt. I've just loaded the font with its default CharSize and then changed it within the string.. I've set both to 13 now, but its not much better.. Its really looking grainy.
MyFont.LoadFromFile("C:\\Windows\\Fonts\\Verdana.ttf");
sf::String MyString;
MyString.SetFont (MyFont);
MyString.SetText ( "test 1 2 3 4 5" );
App.draw (MyString);
