Thank you all. ChromeStar the last available driver update was back in late 2016! Things move on so quickly! When we get this 'plague' sorted I hope to get a new machine. Even so my present computer renders pretty quickly . Compared to older versions of Poser ( I go back to 3) the speed, capacity and stability of 12 are all excellent. (I can render now without crossing my fingers or wondering what I could remove from a scene to have a chance of a complete render,) That said I hope it would not be too presumptuous to thank Larry Weinberg and and subsequent developers for the pleasure that Poser has given me, Seasons greetings!
