I'm interested in how people's render times vary.

I'm currently using an old 2014 iMac i7 4GHz quad-core and CPU rendering of course due to AMD Radeon R9 M295X GPU card.

I recently came across Jura11's freebies here on Rendo' so maybe we could compare render times of his bathroom freebie: https://www.renderosity.com/rr/mod/freestuff/bathroom-freebie-wip-superfly/77018

The scene has a default render dimensions of 1920 x 1200 and the render settings with 45 pixel samples in SuperFly. On my iMac it took 8,105 seconds to render...

Who wants to post their render times and make me sad? ;)

That's a really nice freebie.

12 core processor, 64 Gb of RAM, Nvidia GeForce GTX 1080, Windows 10.

Poser 11, GPU: 1965 seconds Poser 11, CPU: 6613 seconds

Poser 12, GPU: 1858 seconds Poser 12, CPU: 5827 seconds

I am on an old, but very well built machine.

6 core i7, 16 GB RAM, gForce GTX 970, Windows 10.

Poser 12 render of this scene with the Superfly settings provided in the resolution given: 2396. 68 seconds.

I had never said the problem with this release was the speed of the renderer.

PoserP11 44,348 seconds (yes, that's over 12 hours) CPU render with the settings that loaded with the scene.

Win 10, AMD FX-8120, 20 gb ram, NVIDIA GeForce 210

I found, for my machine, much smaller buckets are faster so I'll try that and post the results

You guys might find this ( time this render ) script helpful

Okay, with smaller buckets, there wasn't much difference, except I was using my computer to play games and watch movies so I'm sure that affected it.

Thanks for posting guys, it's really interesting to see the difference in black and white a decent GPU makes. Also that Rhia's 970 beats Randy's 1080!

Thanks, Structure, nice script.

I like the Poser12 speed jump, hope the render still looks since with Poser12 - I can't test Poser12 until the Mac version comes out.

For a laugh I decided to try rendering it with branching turned on, it sure does look nicer but the render time was 85,120 :)

Yeah, these freebies from Jura11 are great and show how good the results from Poser can be. I think that bath needs someone sitting in it though ;)

I don't think that's true. I posted four different times, with CPU vs. GPU, and Poser 11 and 12.

For Poser 12, GPU rendering, it was 1858 seconds. Rhia had 2396 seconds.

Yep, I only rendered with the exact settings given with the scene.

ah yes, my bad - makes a lot more sense now :)

I know, it totes confuzzled me too, until I reread his post and went oh, goodie, am not crazy.

For reference here is the time on a Mac using BigSur iMac i9, 32GB ram, RadeonPro XT5700 16GB PoserPro 12 trial version with settings and view as it comes, 50 mins 2.29 secs while browsing the web It's interesting to see that the HDR image didn't show up through the glass - will have to check on that

Is this the very latest version of Poser 12? If it is, there is a serious problem with HDR projection, it will not show up as a background at all. Unfortunately, you may have wasted a render since HDRI is a source of additional illumination into the scene. ATM, your best bet is to use EXR images or convert HDR to EXR until the techs fix the issue.

Thank you for that tip hborre, will give that a try and check the time again. Many thanks.

1265.81 seconds. Poser 12 on RTX2060 Super using Optix.

1134 seconds. Poser 12 on Quadro RTX 5000 using Optix.

Windows 10, Intel I9-10920x 64GB ram.

Just ran this again on my new 16” MBP - M1 Max with 10 cpu cores (so same as M1 Pro) = 3060 seconds or 51 minutes.

Poser 12, Monterey. 

Let’s hope one day we get the Mac/Metal cycles upgrades that Blender has been getting.

Wow, that's a fantastic scene, especially considering it is free. Also a good one for studying materials and render settings. Windows and mirrors in SuperFly have so far eluded me.

Anyway, GeForce RTX 3060 Ti, 723.66 seconds without OptiX, 595.64 seconds with.

IMHO, it's difficult to compare render times as settings may need adjustment due scene complexity.

As my twin, now-ageing GPU cards max out, I have to drop 'vols & buckets' from nimble 1024 by binary stages to 64, until either scene renders or must switch to CPU-only.

Also, CPU-only render settings may need tweaking to get all available CPU 'threads' working. Asking local or queue CPUs to use too many 'vols & buckets' typically causes a fail-over to use but one 'thread'. After I figured this 'oops', my network-render 'Box' ran jobs ten times faster. In fact, it rendered a dozen times faster, because of the several minutes of file-transfer time for each job...

Tangential, may we have a queue-render sub-forum ? The better to solve such 'gotchas'...

Oh... I had this scene since Jura11 published it, but I hadn't seen this thread sooner, so that I made the test: 1072'' or 17'52" on my 2080Ti, and I was watching videos on Youtube during the calculations.

After installing the zip, I opened the pz3 and started to render as set. However, I got impatient. After 310/2025 (IIRC) tiles took 908.84 secs, I quit. I extrapolated (assuming the same rates) it would take 5937.8 secs, so I tried another render setting. Same size but using the Ultra GPU preset along with checking reflective and refractive caustics.

This took 3548.63 secs (about an hour). Poser 12 Superfly.

Before this render, I also did a High GPU which rendered at 997.6 secs.

VedaDalsette, I think you'll find that the Adaptive Sampling made most of the difference there. It does the same on my MacBook Pro too, setting it to 0.002 for me reduces the render time by over 30%. Obviously higher values mean more noise and lower quality - but I find it a good tool to use for quick renders before final.

I started this thread as I wanted to see what people thought were acceptable render times so your comment about getting impatient certainly adds the that body of results, thanks. 

Personally I've always left my computers rendering while I sleep so final render times don't tend to bother me too much - but obviously faster preview render times while working are better.

I chose this scene for this thread as it was moderately complex with high default render settings, was free and would provide a good compare across a variety of machine specs. It's been real interesting so thanks to everyone who took the time :) 

ader, I may not be the best judge. I'm not an artist. Right now, I'm working on a graphic novel with pics of not the best quality (75% jpg) so I can cram the most pics in before hitting amazon's 650MB limit for graphic novels (or is it the Kindle Kids Book Creator limit? Can't recall.) I just like to play with Poser for stories. I may end up finishing all the pics and then writing the story as prose, as I've done many times before. My impatience has to do with the hundreds of pics I like to produce for a story. Although I fully appreciate the artistry in many of the images I see on this site, image quality takes a back seat, in my case, to the story. (But I'm still keeping all my png renders and scene pz3s in case I change my mind!)

Of course, the workings of Poser interest me. That's why I took your test. And thanks for the link to jura11's bathroom scene. It's lovely!

The canyon is not showing up in the mirror. Is that a Ray depth issue?

prixat, that's interesting. What a good eye you have. (As I said earlier, I'm no artist.)

I didn't change any of the parameters in the pz3 (I just changed the render setting to Ultra GPU for my test). So I poked around and found this:

The EZInner object that came with the pz3 didn't have Visible in Rayt checked! That could make a difference. So I checked Visible in Rayt and Light Emitter and did a fast Low GPU render. No luck.

I changed the Bathroom_1 object Light_184 mat emission from 10 to 1. Rendered again. No difference, so I set it back to 10. I changed the hdr image. Rendered again.

I saw a slight shadow of treetops, so next I made the shower glass and window glass transparent. Rendered again.

So the shower glass is missing but the reflection is still Nothingville. I give up!

TBH, it appeared that there is already an emission coming from that direction already, regardless of whether there is an hdr or not.  Compare the images with and without hdri, there is no difference in the lighting.

prixat, I found where Ray Depth is noted, on the LightPath node. The blending value on 2 bath glass mats has that node attached to their Is Shadow Ray parameter.

hborre, I tried what you suggested but couldn't find the emission, until I used another camera to poke around outside. Two big fat area lights are slammed right up against the windows (on the wall and on the skylight).

So I turned off those area lights, left the 3rd infinite light on, made sure the EZInner and EZOuter were visible, gave it another try (Low Adaptive GPU for speed)—and we now have the hdr reflected. Whew! Glad that's over.

Well, that looks much better.  Glad you were able to figure that out.  Definitely, that shader needs to be corrected in the model before it drives someone else to drink.

Does that mean the HDR was visible through those big fat area lights on the main window? ...but if you look at things through a mirror you can see who the aliens are! LOL

prixat, I'm guessing that's some reference to a movie/series/book I'm not acquainted with, but, aliens aside, that light must have been bouncing off the shower glass and doing blinding light crap (as light is wont to do).

hborre, I realize this was a "is the computer plugged in?" moment. When there appears to be too much light, look for the damn light! Ha! As for being driven to drink, my martini days are over, but edibles, on the other hand...

Still not clear on what was doing the emission. If it's a piece of geometry can you highlight it or name it? I'm importing into other software and the lights and EZ-domes don't do anything for me, they just get deleted.

It looks like the HDR is making minimal contribution to the lighting!

Sorry, prixat, but I'm done with this one. I just wanted to share my render times, as ader requested, and then you got my curiosity going. Besides, I'm not clever enough to know exactly what's causing the white-out in the reflection. Good luck!

Very nice render.  I like the retextured walls and floor.  I changed all the lighting to Blackbody illumination to give it a warmer look.  The recessed lights needed a little boost in strength.  The whiting out is due to the raytrace rays from the camera bouncing back instead of traveling through the glass mesh.  The Ray Depth took care of that.
