Drip just an fyi that your Iteration Rate stat is actually 3.650 (that's a resounding "Yay!" from me for the wonders of built-in data collection redundancy.) Any chance you'd be up for benching with OptiX and/or in the current 4.12 Beta as well? You finally get the full benefits of raytracing there.

I don't have the beta installed, so no results from that I'm afraid.
Not entirely sure, but I *think* the Optix Prime version was actually a little bit faster to converge the first ~20%, though it still ended up slightly slower overall. So the initial iterations might be better in quality, the time per iteration is slightly longer.

I don't want to muddy the waters, so consider this anecdotal.. but wanted to just test the new render server - so threw the benchmark on it and..

Rendered snapshot in 69.6524s

ETA that's 4x 2080ti's in there now, sent via DS 4.12 on Iray Server 2.53 (so Iray 317500.2436)

By all means, muddy the waters (post as much benchmarking data/hardware details as you can stand.) 'Tis the reason I created this benchmark/thread in the first place. I can always just not include whatever other data you have if it proves too convoluted to get into the graphs/tables above.

Btw do you run Iray Server on Windows or Linux? Because in case you don't already know, running it under Linux will give you some MAJOR surprise perks.

Currently Windows, since clustering only works between the same OS's.. and I wanted to try and get that working with my work rig. Initial attempts saw some bugs, but I didn't know if it was due to the fact I was mixing the cards. Now everything is 2080ti's between the two machines, I'll try again.

But yea, it would be nice to try a Linux distro at some point.

There's been LOTS of hay made about whether or not Iray is currently capable of implementing VRAM pooling across multiple GPUs. The full truth of the matter (and this is information I was only able to finally tease out properly as recently as two weeks ago after months of exhaustive research) is that it DOES (and has been capable of doing so for years) - but only in the case of Iray Server being run on a Unix-based system with the addition of NVLink bridges with capable Turing cards (like your 2080Ti's or my Titan RTX.)

The key sticking point for compatibility under other operating systems is apparently in the way graphics cards and their indivial hardware components are enumerated as devices by the operating system. Both modern versions of Windows and Mac OS handle io operations with onboard graphics memory directly, whereas Unix systems farm the task off to the manufacturer's driver (assuming one exists, of course.) This is key because Nvidia's implementation of memory pooling (what they loosely refer to as enhanced Unified Memory) is enacted at the basic io level. Making it currently a no-go on OS X or Windows unless Apple/Microsoft start tailoring there own low level graphics card support systems (eg. WDDM) to fit Nvidia's own proprietary implementation needs...

@AelfinMaegik see here for the right template to use in your case (adjusted the wording to hopefully make it more obvious.)

Here's how it works out for your results:

I like that comparison to 4.10. That really shows that while 4.12 beta is faster than 4.11, it is STILL not as fast as good old 4.10 with OptiX enabled. My own tests mirrored this as I still have 4.10 installed, too. Sadly we have no way of ever testing 4.10 with RTX cards.

While we cannot directly compare GPU results to different versions of Iray, we can compare the different versions of Iray against itself when using the same hardware. 4.10 is still the fastest version of Iray for people who do not have RTX cards. This is why I kept 4.10 around. I suppose if I make the jump to RTX then I wont have much choice but to let 4.10 go. But until then, I will keep rocking 4.10 for a while longer.

The denoiser can be an equalizer. There are specific times I like to use it. In those cases, 4.12 will do.

BTW, there is one special advantage to Iray using full OptiX instead of Prime which may have been glossed over. OptiX does not need to be recompiled for every new GPU launch, unlike Prime. If you you all remember it took a painfully long time for Daz Iray to support Pascal after it launched. Pascal cards were paper weights when it came to Iray. I know Turing worked at launch, but I'll contend that we got lucky Turing worked with 4.11 because it is similar to Volta. Keep in mind that Volta support was added to 4.11 in the months prior to Turing's release. Of course major hardware changes might need updates for support, like the ray tracing cores.

At any rate, what I'm saying is that hopefully the long agonizing wait for new GPUs to be supported by Iray should be a thing of the past now that Iray uses the true OptiX. So I would expect the next generation of GPUs to be fully zippered by Iray out of the box.

Just a thought...

Clearly, our often contentious tech discussions are seen as very disruptive, and that's certainly understandable.

So I'm thinking it might be best for all of us interested in those types of tech discussions to just pick up and move to an unrelated discussion website somewhere. I imagine that would be a huge relief for all involved. Not sure where we'd go, but I imagine there are many choices.

WOW! This really got me wondering since the prime off was faster. I downloaded 4.12.0.42, turned NVLINK/SLI to OFF and tried this, too. I'm really surprised. I am running air cooled, non OC, and I'm shocked at these numbers. Why is prime off faster? (I am kinda peeved at myself- I changed two variables here... I updated beta version AND i turned off nvlink/sli)

Because you have RTX. Also, if by chance Nvlink was working, that can actually slow performance in Nvlink mode. Nvlink mode should only be used when you need to pool the VRAM, assuming that is possible. This is because of how Nvlink works, since the cards must talk to each other more and share more data this slows them down a little bit VS letting them render apart without Nvlink.

The Daz Reddit is a ghost town. Last post was 4 DAYS ago, and scrolling just a few posts takes you 27 days back. It is a shame that Daz has to be like the NFL...No Fun League.

i understand your points about nvlink. totally expected a minor improvement. but why is prime acceleration OFF faster than ON?

outrider42 · July 2019

Because Prime is not made for RTX. RTX is the whole reason Iray needed to be overhauled. Prime has some key differences between it and normal OptiX. These differences allowed normal GPUs to render faster in the past, but the new ray tracing cores caused problems that required this change. I'm rather surprised that Prime is even available to RTX cards at all. I suppose it still there in case you have a GTX card and a RTX card in your system. Or maybe its for CPU. Full OptiX has no CPU support at all.

It would be great if Daz could add a toggle for ray tracing cores, even if there is no practical reason for it other than gauging how much faster RTX on might be. However, people are quite curious about such things.

Yeah, this is extremely interesting.

Logically neither you nor Aala should be seeing any dscernable difference in render times between OptiX Prime On vs OptiX Prime off tests here because, in the case of rendering with only RTX GPUs on Daz Studio 4.12+, OptiX Prime is disabled internally by Iray and all raytracing is farmed directly out to the RTCores on the cards themselves. Currently the only programmatic difference between OptiX Prime checked/unchecked with 20XX cards in 4.12+ is that one state pops up errors in the log file about optix prime being improperly called for when it isn't supported versus a clean log file with no extraneous error messages (renders still finish successfully either way.) At least that's been the case with my Titan RTX under 4.12.0.033. Could you post log files (at least the portions starting after "Rendering image") for both an Optix Prime On and Off test run? I'm gonna try doing the same with my Titan RTX tomorrow on 4.12.0.042 as well, and would love to be able to compare what my logs look like compared to yours.

Btw could you also try OptiX Prime on vs off with just a single 2080Ti activated and see if the same patterns are true? It could be that what both you and Aala are seeing here is a multi-GPU thing. Specifically I'm wondering if perhaps the current DS/Iray version has a bug where having more than one RTX card activated at once is causing Iray to revert back to its pre-RTX GPU era behavior where OptiX Prime is used rather than RTCores for raytracing. Meaning that there may be a DS/Iray bugfix in the near future that could net both you and Aala a noticeable speedup in dual 2080Ti rendering scenarios regardless of whether OptiX Prime is checked on or off..

That's been what my testing so far has indicated. OptiX Prime still registers as on/off in the log file as it always has in the case of my GTX 1050 laptop, whereas my RTX machine says its unsupported. I'm assuming that if I had a GTX card in my RTX system as well and had it selected instead, OptiX Prime would once again appear as a valid configuration option in the log file like it has in the past.

outrider42 said:

So far it seems to be just Embree used for all raytracing functionality in CPU based rendering on 4.12+ (based, again, on my testing so far.) I remember reading somewhere that speedups in Embree's codebase have pretty much made it independently as good (if not better) than OptiX Prime ever was in accelerating raytracing. Thus the utilization change.

Would be nice, but I'm pretty sure that's soemthing Iray's developers would have to first develop and then Daz's developers implement in order for us to have use of it. Not inclined to hold my breath on all that happening.
