    So to clafify, even though the progress bar indicates a percantage, that's not actually showing the convergence percentage, it just shows how close the render is to finishing.

    So when I render the benchmark scene, it is set up to stop at 95% convergence when the progress bar gets to 100%. I see now that this is the default convergence ratio for DS.

    I think I've got it now.

    Correct.

    Some fresh (sub-optimally cooled) Titan RTX Sickleyield benchmark numbers for the DS 4.11 Pro non-beta just released:

    System Configuration
    System/Motherboard: 
    Gigabyte Z370 Aorus Gaming 7
    CPU: Intel i7-8700K 4.7GHz (all cores)
    GPU: Nvidia Titan RTX
    System Memory: Corsair Vengeance LPX 32GB DDR4 @ 3,000MHz
    OS Drive: Samsung 970 Pro 512GB
    Asset Drive: Sandisk Extreme Portable SSD 1TB
    Operating System: Windows 10 Pro 1809 17763.557
    Nvidia Drivers Version: 380.86 SRD
    Daz Studio Version: 4.11.0.383 64-bit

    Benchmark Results
    OptiX Prime Acceleration: Off
    Total Rendering Time: 1 minutes 10.1 seconds
    CUDA device 0 (TITAN RTX): 5000 iterations, 2.050s init, 66.969s render
    Iteration Rate: 74.661 iterations per second
    System Overhead: 3.131 seconds

    OptiX Prime Acceleration: Off
    Total Rendering Time: 1 minutes 24.61 seconds
    CUDA device 0 (TITAN RTX): 5000 iterations, 2.084s init, 81.627s render
    Iteration Rate: 61.254 iterations per second
    System Overhead: 2.983 seconds

    TL;DR Analysis: Virtually identical rendering performance as the previous 3-4 Beta releases (4.11 official is currently still using a pre-RTX version of Iray.)

    As many users I run to get a new RTX card, one 2080 TI. I was using 2x 1070 at the time. 
    The results, however, were disappointing, 2080 TI achieve the same time as dual 1070, but dual 1070 are a lot cheaper than one 2080 TI. 
    I put the blame on the beta version and didn't published until yesterday when I saw the new 4.11 official build.  

    CPU: Ryzen 7 1700
    RAM: 64gb DD4 2400mhz
    MOB: Asrock x370 Killer SLI

    Using file iray_bench_2018_b223da33.duf

    GPU Only
    Daz 4.10.0.123 Pro Geforce 416.34
    2x 1070(Monitor On 1) + 1070 - Optix On  = 4 minutes 39.4 seconds 
    2x 1070(Monitor On 1) + 1070 - Optix Off = 5 minutes 15.1 seconds

    Daz 4.10.0.123 Pro Geforce 417.01
    2x 1070(Monitor On 1) + 1070 - Optix On  = 4 minutes 39.1 seconds
    2x 1070(Monitor On 1) + 1070 - Optix Off = 5 minutes 21.69 seconds

    Daz 4.11.0.123 Pro (Beta) Geforce 417.01
    2x 1070(Monitor On 1) + 1070 - Optix On  = 8 minutes 0.85 seconds
    2x 1070(Monitor On 1) + 1070 - Optix Off = 8 minutes 51.79 seconds

    Daz 4.11.0.236 Pro (Beta) Geforce 417.71
    2080 TI (Monitor on) - Optix On = 5 minutes 26.36 seconds
    2080 TI (Monitor on) - Optix Off = 5 minutes 14.74 seconds

    Daz 4.11.0.383 Pro Geforce 430.86
    2080 TI (Monitor in other gpu) - Optix On = 4 minutes 57.46 seconds
    2080 TI (Monitor in other gpu) - Optix Off = 5 minutes 5.68 seconds

    So I tried to apply the Denoiser resource, that were the variations
    Denoiser Available (On) Denoiser Enable (On) Denoiser Start Iteration (8) Denoiser Denoise Alpha (On) Optix (Off)
    5 minutes 5.48 seconds
    Denoiser Available (On) Denoiser Enable (On) Denoiser Start Iteration (8) Denoiser Denoise Alpha (On) Optix (On)
    4 minutes 46.85 seconds
    Denoiser Available (On) Denoiser Enable (On) Denoiser Start Iteration (8) Denoiser Denoise Alpha (Off) Optix (On)
    4 minutes 46.70 seconds
    Denoiser Available (On) Denoiser Enable (Off) Denoiser Start Iteration (8) Denoiser Denoise Alpha (Off) Optix (On)
    4 minutes 47.64 seconds

     

    Edit: I was curious about how IrayTestSceneStarterEssentialsOnly.duf would be: 1 minutes 9.97 seconds Optix(on)  and 1 minutes 25.19 seconds Optix(off).
    Adding more details, in my previous set I had:
    1x Asus 1070 Dual Oc on 1st PCIE x16 (Monitor attached)
    1x Gigabyte 1070 Mini ITX on 2nd PCIE x16
    Windows on dual 240GB SSD Intel 730 on RAID 0
    Daz Content on 2TB HD SATA3 Seagate Barracuda

    Current set:
    1x Galax RTX 2080 TI OC DUAL on 1st PCIE x16
    1x Gigabyte 970 Mini ITX on 2nd PCIE x16 (Monitor attached)

    Keep in mind that the Iray renderer version shipping with 4.11 General does not yet have full RTX hardware ray-tracing acceleration support. Meaning that there should be a major performance uplift for your 2080ti some time in the near future.

    Your RTX 2080ti has three advantages over the dual GTX 1070 setup.
    1.  It only uses 1x double height PCI-e slot instead of 2x Double height slots
    2.  11GB of VRAM (3 More than the GTX 1070)
    3. RTX cores (when support gets added into Iray

    I ended up using the second PCI-e slot to put a weaker card for Windows, as my cpu Ryzen 7 1700 doesn't have onboard graphics. My goal was let the 11gb just for render.

    I notice that you are using 2x Xeon E5-2650V2, I recently bought these two from Aliexpress to replace one i5-4690k, it's hard do find benchmarks on Google.  Just for curiosity, how good they perform with Daz?

    A number of people saw render times for my benchmark (Iray Bench 2018) go much higher with Daz 4.11 beta. But it becomes clear when you test both setups with 4.11 just how much faster the 2080ti is over 2x 1070s. Its not even close. So yes, the beta is to blame if compare times to 4.10. However, the SY Bench doesn't seem to be effected as much as mine. My bench is quite different in design. I certainly hope that the new Iray 2019 update improves rendering speed.

    For what its worth, the migenius rundown on Iray 2019 claims that the new Iray is slightly faster in general compared to the previous. This is before considering the speed up that RTX integration brings.

    Not too shabby. Faster renders, less electrical consumtion, and room for the upper card to breathe. And I've already got buyers for my old cards.

    I keep telling you guys that PCIe is not much of a factor in Iray GPU rendering. There is not much data traveling across the bus during a render. The entire scene is fit into the GPU, where it pretty much stays in VRAM while the GPU processes it. 

    Now things might change if multiple GPUs are involved, but probably not a lot. I am not sure what point we can saturate PCIe.

    Even in the case of GPU pooling VRAM with Nvlink, the Nvlink bypasses the PCIe by establishing a direct link between the GPUs.

    One possiblity is if we reach a point of real time rendering in the future and the scene is animating, drawing many frames every second. Like a video game does. Then the bus speed will be a factor as the data has to move in and out more rapidly.

    I think we can see the biggest impact of PCIe bandwith/lanes on the Iray viewport!

    I've noticed a world of difference there upgrading my GPU

    Just upgraded the secondary card in my workstation from a Quadro K4000 to a Quadro P4000 8GB, so I decided to run the trusty old Sickleyield benchmark to see how it fares.
    Now, keep in mind that this is a single slot card that only uses 105W

    Daz Studio 4.11 Public release
    Nvidia Display Driver ver. 431.36

    And just for fun:

    2019-07-14 00:19:43.877 Total Rendering Time: 1 minutes 23.61 seconds

    For those interested in comprehensive performance statistics relating to the latest Das Studio beta release (now featuring full RTX acceleration support on capable cards) I highly recommend checking out this new thread Daz Studio Iray - Rendering Hardware Benchmarking. Through careful design and thorough testing, it aims to resolve many (if not all) of the issues surrounding accurate benchmarking which have plagued threads like this one over the years.

    Daz 4.12 with Iray RTX is out ! Here my benchmark !

    Iray Test scene starter Essential.

    I7 6700K 4.2Ghz + 32Go RAM 2200Mhz - GTX 1070 x 2 at 1980Mhz

    GPU ONLY - No Optix - 100%

    Daz Studio 4.11 No Optix: 2 minutes 5.44 seconds
    Daz Studio 4.12 No Optix: 1 minutes 28.29 seconds

    More than half minute GAIN !!

    Iray 2019 has some pretty large performance increases even if you aren't on the latest RTX cards. Just to be warned, the first render on the latest version of Iray will take a little extra time, but all renders after that (with the same shaders) should be faster.

    So that means we will never know how much performance gain came from RTX. Great laugh

    Actually, the way I see it RTX prompted Nvidia you completely rework Iray from the ground up, which has resulted in the speed increases we are seeing. In other words, I believe RTX has greatly benefited everybody because of this.

    That is a really nice way of saying we'll never know how much performance came from RT cores smiley

    I think there are still ways to measure it. Like how the 2080ti was right about the same speed as two 1080tis before. All we have to do is see how that figure has changed. If RTX is truly adding something, then it stands to reason that the 2080ti will become faster than the 2x 1080tis, and measuring this will give an idea of how much RTX is helping. So you have your 2080ti, and I have my 2x 1080tis, and we can try this out. I'll be able to play around with it later today.

    Right, good point that should work somewhat.

    Plus we can compare each GPU vs its 4.11 bench and see how each one improves. We should see the RTX cards receive the biggest gains. I'm very curious to see where the lower RTX cards, like the 2060 now stand. If these cards compare very well against say the 1080ti, then that's another sign of how much RTX is doing. I'm thinking back to ray traced Quake 2, the 2060 beat the 1080ti by quite a bit, where obviously without ray tracing the 1080ti easily beats the 2060.

    Maybe I am doing something wrong, because I am not seeing any speed increase at all with either the SY scene or my 2018 scene with Daz 4.12. I am using the newest Creative Studio Drivers, 430.86. Going into the help file I can confirm that Iray is using its 5.0 June release build. It also says it is beta, BTW.

    IRAY   rend info : Using iray plugin version 5.0-beta, build 317500.2554 n, 08 Jun 2019, nt-x86-64-vc14.

    Which means the bugs that have been discussed are indeed all preset with this build.

    My machine: 2x 1080ti. They are not the same model, so they have slightly different clocks. They tend to run between 1949 and 1964 during the course of the render, but that can depend on ambient room temps. CPU i5-4960 @3.5 Ghz 16Gb RAM.

    SY scene OptiX ON
    1 minute 1.87 seconds

    SY OptiX OFF
    2019-07-22 22:27:04.751 Total Rendering Time: 1 minutes 2.18 seconds

    My 2018 scene

    OptiX ON

    2019-07-22 22:12:44.565 Total Rendering Time: 4 minutes 25.70 seconds

    OptiX OFF
    2019-07-22 22:24:17.864 Total Rendering Time: 4 minutes 25.4 seconds

    So just looking at this, OptiX Prime OFF has taken a big leap compared to what it used to be, however, at least in my tests, it can only match the existing Prime ON times.

    And something has gone haywire. I went back to Daz 4.11 and the render time was slower than I've ever seen with it. I also tried 4.10 Pro, and its time was not on par with what I have done in the past. I tried reinstalling my drivers, even switching to the latest game drivers instead of creator studio, and no dice. Somehow installing 4.12 beta has screwed up my other Daz installations!

    OK, I think I see what's going on here, and its not what people think.

    The new 4.12 loads into VRAM faster than ever, its actually a fantastic improvement, but I think some people are confusing this as a rendering speed improvement. It looks like 4.12 renders faster than 4.11, but only slightly. However, compared to 4.10, it is still behind in pure rendering speed.
