I have just asked Peter for details, I am curious about his method. I am not sure if using Cairo will have a meaningful impact here. The bitmap font generator I use has also offers different ways of font smoothing. Perhaps there is something else that Peter has applied, but if it is Pango/Cairo combination then I would rather avoid it in OpenGL. Regards, Orson
