It has been around for awhile. I'm guessing that you are using the OpenGL Display with Poser 7 SR3? Try using SreeD Display.

I believe that the problem stems from the nVidia Card.
Do you have the latest Drivers, 178.xxx???

No idea as to Why, but this cure my nVidia OpenGL problem, see attached.

I changed my card settings fro Theaded optimization "Auto" to "On".
OpenGL now works just fine in both P7 SR3 and PoserPro.
