In animation, camera movement can cause Daz to default to CPU render

Perhaps this is a known issue, but just as a warning to others who are animating...

I spent about 6 hours last night trying to troubleshoot a scene that kept defaulting to CPU rendering after the first frame. Eventually, I optimized the scene down to 3 GB for my 1080ti's, but it was still defaulting to CPU rendering after the first frame. It was maddening! 

The camera was moving around a bit, so I decided to try one last thing. I deleted the camera and made the movement much less. For some bizarre reason, this worked like a charm. The scene rendered properly on my GPU.

I love Daz, but it's strange sometimes.

 

EDIT - I'm a dope. I just went back into my scene file. Somehow, I'd attached TWO very high-poly hairs to the camera by mistake. I am sure that is what was probably causing the dump into the CPU when the camera moved.
