log attached from the runs i posted earlier. i also saw the errors i think you mean but wasn't sure what they meant:
2019-07-30 22:07:59.326 WARNING: ..\..\..\..\..\src\pluginsource\DzIrayRender\dzneuraymgr.cpp(305): Iray [WARNING] - IRAY:RENDER :: 1.0 IRAY rend warn : The 'iray_optix_prime' scene option is no longer supported.
EDIT: just saw your request for single ON/OFF --- really need to hit the sack before work tomorrow but will try after (~5pm MST)
I hear ya. But that doesn't prevent you guys from chatting about this. Or anything else you want. Consider it small noise to signal ratio.
Great. Good to see you you and RayDant there. I'll have to decide whether to make a 2nd account now, my normal account is a bit too... right of center politicallly ;)
Here's what I got doing an OptiX Prime off vs on test in 4.12.0.042 with my single Titan RTX (log file from both runs attached):
OptiX Prime Acceleration: Off
Total Rendering Rendering Time: 4 minutes 4.35 seconds
CUDA device 0 (TITAN RTX): 1800 iterations, 3.200s init, 238.376s render
Iteration Rate: (1800 / 238.376) = 7.551 iterations per second
Loading Time: ((0 + 240 + 4.35) - 238.519) = 244.35 - 238.376 = 5.974 seconds
OptiX Prime Acceleration: On
Total Rendering Rendering Time: 4 minutes 4.36 seconds
CUDA device 0 (TITAN RTX): 1800 iterations, 3.237s init, 238.519s render
Iteration Rate: (1800 / 238.519) = 7.547 iterations per second
Loading Time: ((0 + 240 + 4.36) - 238.519) = 244.36 - 238.519 = 5.841 seconds
In other words, identical results (within margin of errror) for either OptiX Prime on or off. So not at all the same behavior both you and Aala seem to be getting with your dual card setups. Am definitely looking forwqard to seeing what your single card results indicate.
BTW I should've mentioned this earlier, but there seems to be a bug with at least some DS 4.12 Beta installations where the OptiX Prime on/off toggle box is doing the opposite of what it's supposed to (I only get warnings about the no longer supported "iray_optix_prime" scene option being active if I have the box unchecked.) So in the log file you posted, the first run was with OptiX Prime off and the second run was with it on regardless of what the toggle box in Daz Studio was indicating (fwiw this doesn't change the seemingly anomalous nature of your dual card results.)
Its funny we were talking about "betas" recently, because this particular Daz beta seems to be well, very much a beta. Things are wonky. OptiX Prime is still there...but its not? Funny errors, possible multiple GPU issues, there is a laundry list of things that 4.12 beta has that are of "beta" quality, more than previous betas.
One thing I would like to test is mesh lighting. The issue with mesh lighting was that the more complicated the mesh, it made the render take vastly longer. It is such an issue that I tend to avoid mesh lights for that reason, they are slow. That sounds a lot like the discussion over ray tracing cores increasing performance with geometry. So I think it would be a good thing to test. Creating mesh lighting with many polygons and seeing the difference between the the different versions of Daz. I think we would see more of the benefits of RTX with mesh lighting than other lighting.
I suppose reddit is worth a shot. Its a well established place, so nobody has to create a website or anything. And if we go there then maybe it will come back to life.
@RayDAnt sorry sir, this is later than I expected. attaching raw log, I can calc the numbers in an hour or two if you want but doing some other stuff atm. I think these single card numbers are interesting because they show no difference between optix on/of from a stat point. also, what you mentioned about bug on off could be true. my previous log was ON first, OFF second. which matches the opposite theory.

Was looking through the log files for my OptiX Prime on vs off runs in 4.12.0.042 and noticed the following for OptiX Prime On:
Versus the following for OptiX Prime Off:
Notice how OptiX Prime is listed as being used in both cases (including the one with the warning about the "iray_optix_prime" scene option being no longer supported. This indicates that with this version of DS/Iray OptiX Prime is now always used in situations where one or more GTX (which is to say, pre-RTX) GPUs are being used for a render. Meaning that the OptiX Prime Acceleration On/Off toggle in this version of Daz Studio serves no actual purpose (has no actual programmatic effect on what goes on under the hood) and is likely to be removed from the Daz Studio interface entirely with a future update.
Yeah, I'm still on Titan Xp(s) and the situation is the same (OptiX ON vs OFF), especially in 4.12.0.42 (4.12.0.33 was closer to 4.10 with Prime on for me).
I have an thought. While Prime is disabled for a single RTX GPU, perhaps it is possible to enable it with multiple GPUs , in spite of what the event log says. Turning on Prime for an RTX card SHOULD mean that the ray tracing cores are disabled, thus giving us a way to test the ray tracing core performance. Maybe that is what we are seeing. The reason it works with multiple GPU could be because it is possible to mix GPU of different generations. Somebody has posted a 1080ti+2080ti time in the original SY bench thread.
I think the option is bugged. It should be possible to disable Prime for non RTX cards, while enabling it for RTX.
All result tables are currently fully updated for those interested.
Can't find it now of course, but somewhere - maybe in the last pre-RTX version of the Iray programmer's manual - I remember reading that in multi-GPU situations all ray-tracing calculations were only ever performed on a single GPU (whichever one was deemed most powerful based on a relatively simple perfomance assessment like clock rate * multi-processor(aka SM) count.) Given the slightly unusual results some have posted here - plus the fact that there is indeed presently a confirmed bug (just recently got an official response about my bug report from the powers that be - Yay!) with how the OptiX Prime acceleration checkbox is/isn't functioning as of 4.12.0.047, I highly suspect there is still a fair amount of optimization/non-critical bugginess to be worked out of both Iray and Daz Studio in the wake of RTX capabilities - especially on multi-card setups.
This thread has gone a bit quiet, so I hope that adding more data is still relevant.
I just added an upgrade to my machine today in the form of an RTX 2080Ti. I found this thread to be useful in making the decision to buy, as the "Iteration Rate" gives a nice number to compare different cards or combinations of cards.
I've run some more benchmarks with the new card, shown below - I haven't included those posted previously for the single 1080TI, single 980Ti and both together as they are already in the tables on the first page.

What I've found interesting (and useful) is that if you look at different cards in the tables on the first page of the thread, adding the iteration rate for two single cards does give a reasonable approximation of the result for those two cards actually rendering together.
E.g, for DS 4.12.033
980Ti: 2.587
1080Ti: 3.934
Added together for estimate: 6.5
Actual result for 980Ti+1080Ti: 6.4
1080Ti: 3.934
2080Ti: 6.785
Added together for estimate: 10.72
Actual result for 1080Ti+2080Ti: 10.73
It might not give an exact number, but for someone thinking of upgrading and still keeping the old card in their system, it seems to be a good estimation.
I know people love to hate on Iray, but honestly the more I learn about its inner workings (and how it fits into Nvidia's wider professional enterprise-level software platform) the more respect I have for it. I mean, how many current game engines/graphics rendering suites can you name that feature almost perfect multi-GPU/CPU performance scaling with modern computing workloads? I'm sure there must be at least a few out there, but you certainly don't hear anyone bragging about it. At least not on the consumer/prosumer level.
I have a 1080Ti, and am thinking about adding the 2080Ti-what power supply size are you using to drive both cards comfortably?
I'm using a Corsair HX1200. Possibly more power than is needed, but I also run quite a few HDDs, and a power-hungry cpu with liquid cooler, so I wanted some overhead.

Seems there's a noticeable performance increase in Iray rendering stemming from the latest Nvidia driver release 436.02 (DS 4.12.0.047 and 4.12.0..060 have exactly the same Iray version, so it isn't that):

UPDATE: Again... Noticed I had the wrong core-count for my CPU. (18/36 not 16/32)
UPDATE: Again... I added the new numbers for the new nVidia drivers and updates some computer info. (PCIe slot and lanes and correct CPU speed). I ran additional benchmarks for TCC modes, but only Single and Dual Titan-V cards in TCC mode. For the Titan-Xp Col Edi, I only have one in TCC mode, because the other is my video display. Both updates are for 4.11 and 4.12-Beta versions of Daz3D.
UPDATE: I managed to cram all four cards in one case! I just had to break the intake guard off one of the Titan Xp Collectors Edition cards and bend one mounting-tab over, on the other one. (They wouldn't fit next to one another or within the last slot, otherwise.) So, I am testing Titan-V (2x) and Titan-Xp Collectors edition (2x) cards.
For what it's worth, my Titan-V cards seem to have the same exact results as the Titan-RTX cards, for obvious reasons. That is reassuring and a little depressing at the same time. :) RTX cards are cheaper and have RTX, with the bonus of having more memory... I should have just waited for RTX to be invented.
However, my cards don't seem to be any better, and are actually a little worse, in TCC mode, on prior benchmarks. (Might have to do with windows finally having fixed WDDM mode, finally. That, or TCC mode just offers little for the original Titan/Volta {non-RTX} cards.) Again, I'm a little sad about that.

NOTE: Total system power is the power, measured at the wall, with a "Kill-A-Watt" meter. This includes the total power of the CPU, GPU, Drives, RAM, Fans, Water cooler and Power-supply losses. Eg, it is not a measure of any single specific thing. It is the total potential cost to render, using the entire computer. The actual wattage consumed, must be calculated by the time it took to render. [Watts per hour] / [3600 seconds in an hour] * [Seconds to render] = [Total consumed watts] Now you multiply "consumed watts", by the number of pictures a day/week/month/year, you intend to render. That is what your electric consumption will be, in watts. Thus, it is not better to have two cheap cards that render as fast as one card does, as you consume 2x more power, which will cost you more than you saved when buying two cheaper cards, instead of just one card. (You also have to include AC cooling costs too. Roughly 1.5x what it costs to generate heat, of the same wattage.)
NOTE: Each Titan-V pulls about 100 Watts each, when rendering. Each Titan-Xp Col Edi card pulls about 200 watts. The running system pulls about 160 watts. Thus, (100 + 100 + 200 + 200 + 160 = 760 watts), which is the power draw of all four cards running. The Titan-V is 2x faster, and runs at half the power of the Titan-Xp Col Edi cards. You can fit up to 8 cards in one system, but windows will only see 4 of the same card type. (IRAY/Daz3D may see them all, if at-least 4 are in TCC mode.) Thus, 8x Titan-V's would pull a total of 800+160=960 watts. 4x Titan-Xp Col Edi would pull the same power, but be 1/4 the speed. Both systems could easily be run off of a 1200 watt power-supply. I just wouldn't trust that system to play games, as the cards draw nearly 2x more power when playing games.

That is $9.79 for rendering and about $14.69 for AC cooling, for a total of $24.48, to render for 257 hours total.

END OF RESULTS
Eg, I will save 50% in electricity costs, using 1x Titan-V, V.S. using 2x Titan-Xp, to render the same quality level. Or... This setup is like having 3x Titan-V cards, with 1/6th more power used, to render the same as 3x Titan-V cards would normally render them with. Much better than my older Titan-X card was doing, alone!
Just for fun, I did this benchmark with 4.12-Beta, using 1024/2048 sample sizes, quality 2.0, caustics on, and denoiser. Running it for 15min and 6.23sec (It didn't stop at 10min, where I told it to. :P) Attached is the result of the test. It made it to only 8% convergance.

P.S. I'd still rather have 4x Titan-RTX cards in my machine. This scene would render in 40 seconds! But I would need 8x Titan-RTX cards to bring it down to a 20 second render-time. Soon...

WDDM vs TCC Performance Uplifts Across Daz Studio Versions
Interesting how only the Titan Xp seems to break the overall pattern of 4.11 giving a slightly better increase than 4.12. Makes me wonder if that 6.967% is the result of an outlier (this is all based on minimal sample sizes afterall.)
I think it has to do with the refined "Pascal" code. IRAY had a major update, specific to pascal. I would assume that the "Volta/RTX", will get a similar boot, in time, but comparatively, it is a good thing that WDDM mode is nearly the same as TCC mode. Translation, windows is not hindering the cards as much as it does with the Pascal cards. Also remember, WDDM has had a big update, to fix the memory hogging issue. There may also be no more "debugging watch-dogs" for "pascal cards" in IRAY too. {Nothing to see here, move along! Pascal works fine now. Lets monitor "Volta", like a hawk!}
(Windows treats all cards as one large card now. With or without SLI. It would lock-out large chunks of memory, at the windows level, which made the cards NOT have that memory available at the hardware level. Programs had to use "windows", to "ask for memory", and then windows would surrender it. Now, windows listens to hardware requests, and is not so memory hungry across all cards. It was consuming up to 4GB from each of my 12GB cards, at times! The worst part was that hardware still indicated that nearly all 12GB was still available, but Daz3D would just crash if you actually tried to load a 8.5GB scene. Windows wouldn't release that memory, because it couldn't hear the hardware-level requests and hardware-level access couldn't use it, because windows failed to release it.)
Also, my Titan-Xp CE cards run (stock) at about 2000Mhz, nearly 2x what my volta cards operate at. Consuming up to 2x more power in the process. (For the record, you should include the "CE", or "Col Edi", or the full title "Collectors Edition", in the benchmarks, these are NOT the old "Titan Xp" cards, or the older "Titan-XP" cards.
There are actually four Titan versions, before the RTX. None are the same...
Titan-X (Maxwell version) {I have one of these too... it's half the speed of my Titan-Xp CE cards.)
Titan-X (Pascal version) AKA: Titan-XP (Capital "P")
Titan-Xp (Official nVidia Pascal identified version) (Small "p")
Titan-Xp Collectors Edition (Two flavors of the same card. Slightly faster than the Titan-Xp.)
Then came...
Titan-V (First "Volta series", solid chunk of pure matrix calculations. All or nothing.)
Titan-RTX (Variant of "Volta", split pipe-line or segmented-access, and added real-time ray tracing hardware and faster half-precision floating point formulas. AKA: RTX)
Titan-RTV (Not real, but when it comes out, it'll be used to travel across country when we retire and hold car parts together like auto-caulking.)
I'm glad to see a Titan V finally added. So the Titan V can indeed be faster than the Titan RTX in Iray. This proves that the numbers Migenius have been posting have been pretty correct all along.
https://www.migenius.com/products/nvidia-iray/iray-rtx-2019-1-1-benchmarks
The Titan V gets a clear victory in 4.11, showing that without its dedicated ray tracing cores, the Titan RTX is clearly slower. With 4.12 and the new Iray making use of ray tracing cores, the Titan RTX beats the Titan V...by 1 second. This is such a small margin that it falls with margin of error. The two are essentially tied here. And that is with RTX turned on.
I believe this comes down to the lack of double precision (FP64) in the Titan RTX, because the Titan RTX has but 1/12 of the FP64 the Titan V does.
So while the Titan RTX has dedicated ray tracing cores, the Titan V makes up the difference with pure FP64 muscle. So in a Iray battle between the two cards, the winner will be decided by how the scene is designed. A scene that is not as intensive for ray tracing might see the Titan V win. But a scene that really pushes ray tracing might see the Titan RTX win.
In other words, if you have a Titan V, there is no major need to upgrade unless you really need that 24GB VRAM given the two cards will basically trade blows. The Titan V is still a beast. Of course if I was buying a new Titan right now, the Titan RTX is the easy choice given it is cheaper and has twice the VRAM.
Are you sure about that? Because based on everything I've read the CE's are completely identical to the original Xp's other than their exterior accoutrement. And observed during use vs officially published boost clocks isn't itself enough to go by since virtually all modern Nvidia cards' official boost clock specs are hundreds of megahertz lower than reality (eg. my officially 1770Mhz boosting Titan RTX is actually a 1995Mhz boosting card at stock settings.) I'm inclined to think that if you had some vanilla Titan Xp's to play around with, you'd find that they also boost to about the same 2000Mhz as your CE editions.
JD_Mortal, if you aren't already totally benchmarked out by this point I'd highly recommend checking out this raytracing acceleration specific benchmarking effort Takeo.Kensei launched a couple weeks ago. Imo seeing how much/if the Titan V scales up performance-wise in terms of raytracing heavy scenes in comparison to the Titan RTX (see the patterns I found here) would be very interesting to know. If not, that (in addition to the addition 12GB's of VRAM) would be something that would make the Titan RTX an absolete steal over the Titan V - at least for 3D rendering purposes.
I haven't written about it anywhere yet (did it late at night and then forgot about it until just now), but a week or so ago I decided - on a whim - to mess around with Takeo.Kensei's test scene, increase it's complexity approximately 4 times via simple copy/paste, and was actually able to observe an RTX on vs off performance uplift of around 10X TIMES! I'd be very interested to know if any of that translates over to the Titan V with its sheer FP64 horsepower
Ray: I'll throw it on the grill... But, yes, there is a clear leap from XP, Xp and Xp CE cards. (You will see, if we get more benchmarks.) They beat my Volta cards at playing any game... But, as you see, they are no match for "real rendering", compared to the Titan-V. https://www.videocardbenchmark.net/high_end_gpus.html
Summary of the historic sampled values {Passmark scores}... (Higher is better.)
- Titan-V CEO ED: 16,988
- RTX-2080 Ti: 16,761
- Titan-RTX: 16,504
- Titan-Xp CE: 15,100
- Titan-V: 14,912
- Titan-Xp: 14,355 (Also includes some [Titan-X {Pascal} AKA:Titan-XP] {non-nvidia manufactured} and some Xp-CE cards)
- Titan-X: 13,655 (Also includes some [Titan-X {Pascal} AKA:Titan-XP] {nvidia manufactured, but not identified as Pascal}) Should only be the "Maxwell cards here", but the scores are tainted.
NOTE: Many X, XP and Xp cards were "water cooled and overclocked", to get the numbers UP to 14,355 average. Almost none of the Xp-CE cards were watercooled, because they were collectors cards and limited production. The real scores are in the 10,000-11,000 range, stock cooled. Most who watercooled have listed benchmarks. Few with stock setups, ever submit benchmarks. You can see the individual values and the majority of stock Xp-CE cards are in the 16,000 range +/- 300. The Xp cards are +/- 2,500. Range from 10,000 to 16,000. Might just be better hardware and less "throttling" in the CE cards, but, overall, in every test, they are above normal Xp cards.
Outrider: I am sure RTX will get some bigger boosts, when it comes to animation renders or progressive target rendering. Remember, DOF backgrounds don't NEED super precision, but Titan-V will always be limited to doing it. Titan-RTX can, if they eventually code for it, reduce thinking with those slower precision numbers, for those parts. Same with fast moving animations that should be "blurred" and obscured. That is kind-of the point of RTX + Volta. Tween frames can be hyper-calculated faster than a Titan-V could do, in theory. (Including motion-blur and progressive/selective denoising, which doesn't mind half precision floating point values.)
Which is better?
A: One big brain that can think of one thing fast, with one arm... doing something perfect.
B: Dual, split personalities, that are controlling ambidextrous Siamese-twin arms, four of them doing something different, each... but only half as good.
Obviously it's "C", the "Next new card that is yet to be released"... Duh!
Added stats to my post for 2080 super. Wow, it's almost 3 times as fast as my 1070 :D
Are they for the latest beta and driver versions (4.12.0.073 and 436.30 respectively)? Need to know for how to categorize them.
ETA: And also still on Windows 7 SP1?
Ah dang, It's 436.30 nvidia driver and 4.12.0.67, didn't chek for DS beta update in a while. Ill rerun it on latest beta and post that too after supper, since it goes so quick lol.
Cool. Thanks!
ETA: For what it's worth you shouldn't see any render time changes with that update (The beta hasn't seen an Iray plugin version update since 4.12.0.042.)
Yeah, was .4 seconds slower lol. Wow, just tried the benchmark scene in preview render mode, so fast and no lag when I try to move stuff!
