Well 500 bucks later and my renders are chalk full of noise. How do I know Superfly is even using my GPU? No setting to confirm? Just used the default Andy scene and YIKES, noise city. Any idea whats going on? Thanks.

Check your render settings. Any PBR needs lots of samples in order to get rid of noise/fireflies. If I want to get "clean," I set to a minimum of 15–20 pixel samples. Really good quality will be more, but that should be sufficient to get rid of artifacts in most situations.

As for whether Superfly is using your GPU ... assuming you have an Nvidia card, you have to set that in your preferences; otherwise, it will be doing CPU renders only by default. (Be aware too that the tech is such that GPU rendering isn't as capable as CPU in some aspects of quality.)

Also, I'm not sure I would render default scenes in Superfly. PBR is revolutionary like IDL was a few versions back, so far as lighting is concerned.

No setting in preferences for gpu. Just the pull down in render settings if that's what u mean. Takes forever to render. Nvidia with 4gigs of ram and over 3000 Cuda cores. Otoy Octane render in 1 minute. Poser 30 minutes. Ugh.

Don't assume that GPU will render faster than CPU.

But yeah, this doesn't claim to be one of the fastest GPU PBRs.

Dont have to assume. It does. No cpu in existence can compete with 5000 Cuda cores.

Okay, just assume. Others have reported otherwise, but obviously, they are mistaken.

Yes they are. Gpu render exists for a reason.

GPU rendering in superfly is... odd to say the least. Personally I do get better performance on my home GPU (like 2x-3x) but that's mainly cause i've got an oldish CPU and a very powerful GPU (980Ti) I imagine if I had a modern CPU and something like a 970 or lower, the results would be more like what you're getting. And that's really not good IMO. I use GPU rendering in my day job and most of the time it is 10x-20x faster then CPU rendering, that's the main reason we chose it for our projects. We could really use that kind of performance in superfly.

Perhaps it's just a case of superfly/cycles not being mature enough in this department as yet ?

If you have Poser 11 Pro, you can enable GPU rendering in the Render Preferences, Superfly tab, at the right side at the top of the tab. You know that you render with GPU when you see just one bucket render at a time, the CPU version uses more than one usually.

Octane is still faster than Superfly / Cycles, That's nothing new, you can read comparisons in the Blender community.
