It's questionable that the Superfly Render uses the NVIDIA GPU. I was playing around with the Superfly Render settings, mainly disabled multi-path tracing like the webinar video said and adjusting the number of pixels and my bucket size. The video said you should set the bucket size to the number of cores (I assume this means cuda cores). The GTX 960 has 1024. I've experimented from 64 to 1024, nothing overly impressive and slight differences, in fact it seemed the bigger the bucket size the worse the performance. And someone did mention that near the end of the video and they had a much more expensive Titan series card. Anyways, I noticed there would be 8 squares on the screen processing the data, hmmmmm that's the same number of processes I have set in my general preferences. Coincidence? Nope! I adjust that number, and whatever number I set, then that would be the number of squares I would see processing (a bit of a balancing act, big buckets + high number of processes would overlap and skew the results, easy to see the correlation by keeping the numbers low). 4 processes = 4 squares processing data, 1 process = 1 square processing etc... Well that tells me the main CPU is doing the processing and not the GPU. Why don't I hear those big heat sink fans kicking on? I opened up task manager, performance tab and sure enough! As soon as I hit a Superfly render my CPU spikes to 100%. I wish I knew an easy way to monitor the GPU. The webinar made it sound to me that using a GPU is something new to Poser and that they were still working out some bugs with Nvidia. I still don't think they got it working right and I don't think the Superfly engine is utilizing the GPU. In fact, look at this from the Message log - "SuperFly: Start rendering on device Intel Core i5-3340 CPU @ 3.10GHz."
