Do you need to dynamically switch between PolygonMode LINE and FILL, or are you always doing LINEs? Because you could try using a Line Loop primitive instead of polygons. > Has anybody faced similar issue? Any help in this regard will be grateful. I have no experience with this. I know the Quadros have different line-drawing code in their driver, because line-drawing performance is one place where all the money you pay for a Quadro actually makes a big performance difference. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.
