Thanks Iron. I was able to run one with your settings, using my cpu. Not too long. I then tried with my gpu, K-rash. Went to immediate poser gray screen. Weird! So I set the bucket size lower, tried again, same thing, instant crash. This should not be happening, I says to myself. Did some research and came up with this: CUDA error at cuCtxCreate https://forum.smithmicro.com/topic/3854/cuda-error-at-cuctxcreate-launch-failed/11

You have to change a register key and then it will work. In my case I had to ADD the missing key, but it's working now. Sheesh, how is anyone supposed to know this stuff?!!!!

My scene was 2 figures and 1 prop, big prop almost a figure itself. LOTS of reflections from robot skin, pistols and machine prop. Anyway, Superfly rendering scene using CPU 2056.62 seconds or 34 minutes Same scene using GPU 2023.06 seconds or 33 minutes, not a huge difference

Also, I was rendering to 6600 x 10200 at 600 pix/in, NOT 1427 x 1080 so that could account for the "takes forever" part. I like to make large images and shrink them down a bit in photoshop for sharpness. Probably wrong about that too, but then i can make poster size prints.

• For testing I used your 1427 x 1080 size

Anyway, thank you very much for your help. I'll probably play with it some more to see what I can get away with time-wise and resolution-wise.
