Some good news is that I've just tried running the test scene with the demo of Poser 12 and the 1080ti slowdown seems to be fixed. Also, the Optix mode for RTX cards is a LOT faster. Speeds seems to be faster across the board. The bad news is that at the present time, you can't use more than one card to render. Here are the results:

Downloaded Test Scene Poser 11.3 RTX 2080ti 622.54 Seconds

GTX 1080Ti 6600.24 Seconds

RTX 2080ti+GTX 1080Ti 373.8 Seconds

Downloaded Test Scene Poser 12 RTX 2080ti 475.13 seconds.

GTX 1080Ti 531.63 seconds

RTX 2080ti Optix 266.89 seconds.

Thank you, Nails60 - good to confirm that you're on the same version.

A shame that no one can run 11.1 anymore - I would have been interested to see the 1080ti performance before the 11.2 update.

I've been trying out the 11.3 beta today and I've come across the same issue with the 1080ti that others have found. As per Gwild99's post - I just tried the default La Femme scene with the suggested settings.

1080ti: 20.12 sec (twice as long as Gwild99's 1080)

2080ti: 5.00 sec

2080ti+1080ti: 3.64 sec

With the test scene mentioned above (https://www.renderosity.com/mod/freestuff/benchmark-test-scene-for-superfly-/83640), using the settings as loaded, I got:

GTX 1080Ti: 6600.24 Seconds

RTX 2080Ti: 622.54 Seconds

GTX 1080Ti+RTX1080Ti: 373.8 Seconds

I also tried a render with one of the new included scenes - AJ Futuristic Base 5960X 151.41 sec 1080Ti 208.41 sec 2080Ti 14.70 sec 1080TI+2080Ti 10.73 sec

So as others have found, running a 1080ti with another card seems to get it back up to expected performance, but alone it is worse than a cpu render.

I found the thread about 1080ti performance: https://www.renderosity.com/mod/forumpro/?thread_id=2939036

Interesting that several people are finding the same as I have - the 1080ti alone is very slow, but when working with another card (even a slower one), it is running at around the speed that you would expect.

Thanks for posting your results Nails60. I'll have a search for any mention of 1080Ti problems. Interesting that your 1080 is rendering the scene in around 1/6 of the time. What version of Poser 11 are you using?

It is dark, which likely increases the render time with Superfly. But that doesn't explain the huge difference between the GTX 1080ti and the RTX 2080ti - especially since both together show that the 1080ti is having a reasonable effect on render time. Not sure if a HDR would add much since the scene is "indoors", but I'll have a go with more lighting to see what difference it makes. The final scene that I rendered - AJ Futuristic Base - is very bright, yet the speed of the GTX 1080ti still seems wrong, especially when compared to the CPU render. Huge improvement with the 2080ti though.

I downloaded the 11.3 beta and ran some test renders. I'm getting some very strange results - maybe there is some work still to be done on this version.

With the test scene mentioned above (https://www.renderosity.com/mod/freestuff/benchmark-test-scene-for-superfly-/83640), using the settings as loaded, I got:

GTX 1080Ti: 6600.24 Seconds

RTX 2080Ti: 622.54 Seconds

GTX 1080Ti+RTX1080Ti: 373.8 Seconds

This seems to be a real rendering problem for the 1080Ti, which doesn't seem to be the case in earlier version of Poser running this scene.

I set up a scene using La Femme for a portrait: 5960X 25.86

1080Ti 286.28 sec

2080Ti 190.61 sec

1080TI+2080Ti 71.98 sec

Finally, I loaded one of the new included scenes - AJ Futuristic Base 5960X 151.41 sec

1080Ti 208.41 sec

2080Ti 14.70 sec

1080TI+2080Ti 10.73 sec

Even on these much smaller scenes, the 1080Ti seems to be struggling. Admittedly, I am very out of practice with Poser, so I didn't do much in the way of tweaking bucket size etc, but I would have though that would not have had an effect on the difference between the 1080Ti and the 2080Ti. I wish that I had run a test using Poser 11.2 first.

@fingers - Sorry, this is the first time I've been back here for a few months and only just saw your post. Very glad to hear that you got it installed.

You're welcome, Forester. I'm pretty sure that I've used some of your products in the past, so support for previous versions is always appreciated when it is possible.

Just in case it helps, I am running 64-but Vue 7 Inf, on windows 10 Pro 64-bit, and was previously running the same on my Windows 7 machine. I haven't tried 32-bit Vue 7 on either Windows 7 or 10.

As another example, as a vendor of Vue "stuff," I'm having trouble trying to make some products available for Vue version 7. I know a good person on a very limited pension who has only Vue 7, and has been pleading with me to make some of my stuff work on that old Version of Vue. I'd love, love, love to be able to do this, but I can't even buy the hardware pieces to make a computer, let alone the old version of Microsoft Windows need to make this possible. (And I build my own computers, so if anyone could do this, it ought to be me!) But it is frankly impossible for me to build a rig that will run Vue 7, even though I've kept the software (since I go back to "Vue 1.00). I don't even want to think about the kind of nightmare it would be to try to port some of my products back to that old version.

Not sure if I've misunderstood, but why would you need an old version of Windows to run Vue 7? I'm currently running Vue 7 Inf and Vue 11 Complete, under Windows 10 Pro. Vue 7 runs perfectly. Unfortunately, the terrain editor in Vue 11 Complete crashes unless I run it in OpenGL Software mode.

Actually, just realised something - is there a difference in how plugins work between 32-bit Vue and 64-bit Vue, hence the need for 32-bit Windows?

Just wanted to pop in and say a big "Thank you". I wanted to try this script when you first released it, but the main reason I don't use DS is because of the content interface. It has taken me several installs of DS and the content to actually get Genesis 3 working in DS. After that I had problems with an invisible Gen3 appearing in Poser. I finally had another go this morning and managed to get the base G3 figure into Poser.

After that, I installed the “Genesis 3 To Poser” utility by willdial and it worked instantly. Thank you very much.

Superfly took a bit of experimenting, especially since it didn't seem as fast with GPU as it did with CPU - increasing the bucket size helped a lot (I'm still experimenting though.)

Here though, is a test render of Aiko in Superfly rendered on "Medium" settings. Originally rendered at 810x1080, it took a couple of minutes on a GTX 980Ti.

When I got back off holiday I downloaded Vue 2015 PLE and tried a few test renders.  The difference between Vue 11 Complete and Vue 2015 PLE are variable depending on the scene being rendered.  Also, my apologies fgor a mistake in my previous posts - It's Vue 7 Inf, not 6.  When doing the tests I was very much aware that there are differences in the render engine between the versions, so the tests aren't as scientific as I'd like.

                                                     Vue 7 Inf                 V11 Comp                   Vue 2015 PLE

Horse @1024                                45 sec                    1 min 17 sec               1 min 16 sec

Displacement 2 @ 800x533          3 min 18 sec           3 min 19 sec               2 min 22 sec  

Reflective spheres                        13 sec                     17 sec                        7 sec

Spheres 2 @1920x1080                21 sec                    25 sec                        12 sec

HDMI City scene @1920x1080      1 sec                       2 sec                          4 sec    

So overall, there is usually a speed increase from using Infinite versus Complete, which is not surprising, but what is surprising is that it isn't always a huge difference.  On some scenes (the Horse for example), the speed differences were much lower because of one thread taking a lot longer to finish rendering an area (perhaps lowering the bucket size, which I'm not sure how to do in Vue).  For now though, it's satisfied my curiosity and I can live with Vue complete for a while longer.  Thank you once again to aeilkema for the PLE suggestion.

I have used the PLE versions of Vue before and didn't think of this, so thanks for the suggestion and the explanation. I'm away this week, but I'll give the PLE a try and post back - I can't afford to go back to the latest version of Infinite right now but I am interested to see what difference it will make. 

Not as much traffic here as I expected!  Lacking advice, I installed both Vue 6 Inf and Vue 11 Complete on the new machine and did some tests.  The results are not quite as simple as I first thought because I hadn't taken into account the optimisations to the renderer in Vue 11 vs Vue 6.

I thought that the information might be useful to anyone else who is thinking of upgrading either their machine or their copy of Vue.

Test 1: (4 spheres of different materials on a checkerboard):

Vue 6 Inf: 15 sec            Vue 11 Comp: 23 sec

Test 2: "Glass Horse" scene from Vue 6, rendered at 1024x768

Vue 6 Inf: 21 sec            Vue 11 Comp: 1 min 16 sec

Test 3: "City" GI Atmosphere with a 49cm Sphere with "ruby" sub surface scattering material, rendered on Final at 1920x1080

Vue 6 Inf: 22 sec            Vue 11 Comp: 6 sec

Test 4: "City" GI Atmosphere with a 2m Sphere with "ruby" sub surface scattering material, rendered on Final at 1920x1080

Vue 6 Inf: 1 min 11 sec            Vue 11 Comp: 59 sec

Overall, until I can afford an upgrade to Vue 2015 Inf, it looks as though I am better off using Vue 11 Complete because of the better optimised renderer.

As a final comparison, I rendered Test 3 and 4 on my old machine to justify buying the new one to myself:

Test 3 (Vue 11 Complete):

i7 5960X (3.0 GHz): 6 sec                i7 2600 (3.4GHz): 12 sec

Test 4 (Vue 11 Complete):

i7 5960X (3.0 GHz): 59 sec                i7 2600 (3.4GHz): 2 min 27 sec
