SupportRequest: I cannot complete a Superfly Render

I am running Windows 7 64bit, nVidia 980ti 4790K with the latest drivers.

I get about 3/4 through a superfly render then I get a "Video driver has stopped" error message. Then when I close the Poser11 window, I get an OpenGL error message. (This may be because the video driver has reset)

I have set the tdrDelay variable to 60 in the registry and added a tdrLevel of 3 to the same registry area.

I have tried earlier video drivers, swapped my RAM and rolled back to a GTX780ti. All with the same error.

It happens when the render gets to a complex area and it takes several seconds for the current bucket to appear. Straight after it appears, the driver crashes.
