What make and model is your graphics card? CL supports ATI and Nvida for sure. Other makes may not support OpenGL. (They all seem to think they have to do their own thing) P.S. In my town be have a store that specializes in used computer parts. I can get last years latest and greatest graphics card for about $25. If you are on a tight budget check for a computer recycler in your town. If you loaded with cash on the other hand, go buy the hottest ATI or Nvida card you can lay hands on. It really makes a difference to Poser now. Nerd3D
