If the font is not a pixel font, it will render differently depending on your settings and the choices of the rendering engine. Subpixel rendering for the different LCD-screens, aliasing for the pixels to look smooth on low res screens, hinting for those small details to be visible in vector fonts. Vector fonts are made of lines that can sometimes be smaller than a pixel wide. Font engines solves this in different ways. It both depend on the quality of the font and the settings of the engine. (I'm no font expert though so names might be off. But I have been playing on and off with pixel fonts and vector graphics since 30 years)
