I just reinstalled Poser6 after many months of a previous setup, and only just realised there was an OpenGL feature. :-D

Maybe I saw it on the last install and have since forgotten, but this time a dialog came up offering the option. Perhaps the difference is that between then and now I have installed a GeForce* in my PC that can actually do OpenGL.

(* a cheapie off ebay that matches the age of my old box)

The preview window definitely responds faster using OpenGL over Sree3D in Poser6 (even faster in Bryce5.1), but the old Sree still isn't too bad.

"...I think my slot is just hosed."

Remnants of that old ants' nest that was in there a while back? In which case maybe "hosed out" is the answer. ;-)
