Its because Poser does all its renders using the cpu in software, not on the card. All its needs from the card is some way to write and read pixels. The card is nothing more than a pixel pusher to Poser. Hopefully the newer version of Poser will have cool support (DX or OpenGL). Besides, its not like Poser is doing anything spectacular with renders. It doesn't ray trace, only smooth shaded, z-buffered, textured, perspective correct polygons with alpha, bump and reflection capability. Nothing you can't do in DX 6 or 7 today. Of course with seperate hardware your mileage may vary. Some cards may handle the stencil buffers, bump maps and reflection maps differently. Then again, going tpo DX or Opengl could open a lot of doors to new features like Light maps, much higher poly counts and so forth.
