The OS/Browser don't matter. I disabled font smoothing and anyone who has that on on any software/hardware combination will be subjected to output like in my screenshot. To explain this a tiny bit further: Fully developed and professional fonts will have had attention put into them to ensure that they will look perfect in pixel-exact representation at any font size. The font you chose had that kind of work only put in for up to font size 8 or thereabouts and thus looks terrible.
