I don't know why but after last Daz Studio updates I am getting slow down , not only the rendering time but also utilization is long even if the viewport is already open , I did not update to the last Nvidia driver yet as everything was working fine as usual, the viewport working fine as well as before but the moment I hit the render button things get slow, before a single sphere render in 3 sec and genesis full figure in 7 , now it close to 30 sec and it takes couple second before I even see the rendering process in the open window. First I was thinking it may be the new iray shader changes but nope.
In the graphs below I rendered image sequences so the GPU drop each time of new sequence being rendered, the GPU may works at full when you use caustics and or architectural sampler without it , the GPU never reach 100% mostly around 70-86 % , the new driver updates will not speed much unless the Nvidia engine is adjusted to new level, total 2 different worlds of performances here ( rendering vs games) in rendering the driver will not speed up your hardware (cores) as for that Nvidia would have to edit the engine software to response faster in processing the data , the graphic performance I posted was to reflect the changes in the iray engine that improved back then and less for the driver as the changes are minimal with each update and updating to a beta driver may just slow down everything for you as the iray engine is not ready to handle it at that new level.
The best you can do is feed the case and GPUs with air flow from the bottom and on the side panel , better than the side fans , the fan on the side by the RAM will create turbulence sending hot hair to the CPU area from the memory and upper plates of the GPU that can get really hot , best to skip the fan on the side by the memory and use one Memory fan on top or install 2 fans on top for exhausting the hot hair , I had set like that a time ago as my case did not have many options for the fans , but once I feed the case with the air from bottom and side things improved dramatically for the GPU and overall temperature and that was the best $12 I ever spent for the side fan , right now I have open case panel with water cooling only so no more issues
The latter is very cool, I was just looking at something for a rack where sucking air through the solid bottom panel of the rack above it is kind of difficult. For stand alone PCs yes, bottom and side intakes are far better. I am considering tilting the fans akin to what I did on that Graphics card, I just haven't actually done anything there yet (size vs angle fit testing, or crunching any numbers on where the air would go). At the moment it's just a can it all fit puzzle, lol.
As for the Iray thing, I had seen that load cycling on lower end cards with old drivers and was not sure if that was where Nvidia was getting the claimed 3x performance boost on Titan Xp cards in Miya from, lol. I really doubt it would affect older Titan cards, as Nvidia only specified specifically the 'Xp' and not former Titan X cards, with yesterdays beta driver.
oh, putting the fans inside the PC on a vibration dampened panel can do one thing if the case has the volume for it. Act like a band pass sub woofer box. I did that with my workstation, tho I never got around to making any presentation material on the concept. (attached pic is from a Google search)
Oh, one other note, and I thought wrongly as well about it at one time. DDR4 memory is incredibly efficient, to quote Buildzoid, "it consumes so little power you could run it off the ambient energy of the universe", lol. I think the figures were around ten amps for two sticks of DDR4, overclocked and some to the extreme with the CPU under Ln2. Under normal stock clocks, DDR4 consumes so little power that a two phase VRM is just stupid overkill even without a thermal mass (I will not call them things without actual cooling fins heatsinks, lol) on the VRM. Now there is stuff on the motherboard that does get warm, tho that is just par for the course with computer cooling.
If you put tracks down there, you'll get a neat sci-fi tank =)
I know what you mean, I played with that for too long, always fun ! lol
well if the iray engine is upgraded reflecting the new driver there may be improved perfomance in general but not 3 x or even 1 x for rendering as they do not focus on that with the new driver updates , I still not regret my last year purchase , energy efficient and powerful beast that will go for some time and not plan to upgrade soon , too much investment . Since I have 5 Titan X Hybrids , I am thinking about to add the 5th card to the family, I purchased the 5th card for my other PC , but I will need to add more PSU power , something to do for the winter months ;)
Yes it is , and that was also reason why I switch to open case , however side fan can do wonder for the motherboard as well and eliminate hot spots .
Yeah, JayzTTwoCents discovered similar with the Ryzen Production build he made, The case was just too restrictive for two Titans doing video rendering. Tho that was a case with practically no intake vents (The gaps between the panels just was not enough). I remember when He did a review of the case and my glaring question was where is the intake vents. Over a month later the sad result was, Jay ditched the Ryzen Production build because of lacking 64GB memory support on AM4 and the lacking thermals of the case, And I do not blame Jay at all for that choice. The lacking memory support is why I have not done the Romen noodle diet for a 1700x build yet, and now it looks like Threadripper may be the better choice anyway (given more high clocking cores and more memory channels to work with). As for the computer case, I have not been impressed with any case that came out the past 15 years, there either to child cartoonish looking for my tastes and/or they completely lack sufficient air vents to adequately cool anything beyond a Mobilephone processor, lol. I'm resigned to the fact that I will, and want to, get the cheapest case I can that has a good motherboard tray I can scavenge and build the rest of the computer case from scratch around it.
The tilted raised fans may work, after all, it's just a matter of finding a good height for the fans and angle for the panel there mounted to. The PSU being the tallest part so far, there is plenty of room to work with there.
Ketttu, yeah, After I got the shape of that Graphics card shroud started on the angled end I kept thinking of a star trek shuttle craft or a bullet train, lol. The entire concept of that graphics card cooler, was to not have the fan sucking air through the back of the card next to it, lol.
This was the moment, I decided enough was enough with the current way of slapping a fan on the side of a graphics card. Water is not for everyone, and there are quite a few ways you can end up with another card up against the graphics card outside of Blender rendering a new video intro. Also, Nothing in the PCI-SIG spec dictates the top slot must be for the primary graphics card, I say move it down to the bottom slot and add another two back-plate openings for the two and three slot card coolers.
Ever have one of them days
when you just can't get the minimum info for getting replacement parts
Sysco, Sysco, Sysco, what are you using to cool your equipment, or at least here, what is the minimum CFM the replacement blower needs to deliver.
In any case, the show must carry on, there are better fans made by others (like San Ace or Delta) with real data in the data sheets
FYI, that particular no-name blower is in the Sysco Catalyst2970. Nidec may be a reputable company, however that particular fan (blower) is NOT in their portfolio. And I need to replace it, NOW.
I'm guessing the San Ace "109BM12GC2-1" would be sufficient for CFM, I hope 28.9 CFM is sufficient.
ok, Hexagon breadcrumb for self.
I guess some times Hexagon just completely forget's it's settings and reverts to transparent meshes that can make working with some stuff impossible.
I know it was an easy fix, I just could not remember where the setting went. I'll find out soon enough what other settings got forgotten I guess
No, No, No, WTH! I wanted to work on stuff today, not fuss with settings
grrr.
Ok, got that back to normal, what else
grrr.
Looks like that was all, I guess. Working good so far.
I sort of dropped off the face of the earth the past few days, tho some stuff came in and I had some stuff that needed to be done ever since I got this M5A97 motherboard.
So the debate when I went off line to work on my computer was, will it live
. FYI, this was not the potentially deadly part of the mods by the way.
I debated completely gutting the case, tho it would have been completely sterilized metal shavings anyway, and the computer needed a good cleaning after three years of 24/7 use. I actually have not seen this side of the motherboard tray in the case in over three years
What a filthy mess that was.
Yester day the case was cleaned out, and it took considerably more time than expected to get it all back to the point that I could get the pics out of my camera. I actually just got the comp back up and booted just in time for the Patreon-Exclusive Chat with Glenn from SWRC and the crew
.
I still have so much to do to this comp, and I do hope to explain why some of this was so urgent for this decrepit AM3+ motherboard.
Oh, and why did I choose the case colors of red and black, well, I think I need not explain after the above pic from the past
ok, I admit I have not been posting much, it has been a tad busy at best. I did notice after the last Growing up for G3F "Undocumented update"
, that a former saved scene had kicked an error, tho it was trivial and not a big deal at the time.
Last night I went to load a very old scene to grab some settings I had used for something and noticed the same error again, so I guess something is up. (yes I tried a reinstall of the GU pack, and got the same error)
This only appears to affect older scenes saved before the update, and I do not see any thing off-shape or awry other than the error message itself, so probably trivial at best. Loading the old scene and re-saving it with a new file name appears to make the error go away, and this dose does not effect anything else that I've noticed so far. loading G3F from scratch or scenes saved after the update does not kick the error.
In other news, I've noticed, rather blatantly, that some sites are now switching over to a visually challenged friendly font size and layout.
Unlike when the Daz Forum went into chaos, Chrome and Firefox now appear to have a per-site scaling thing that now works.
So there is a workaround for continuing to multitask with sites designed to prevent such multi-window use on workstations, lol. Somewhere around 80% to 90% appears to be ok with YouTube's new layout, and it does not appear to scale the vid just the fonts and buttons.
As a "visually challenged" person, I disagree. This update didn't make my life one bit easier, quite the other way around.
The most annoying thing isn't even the way they messed up the screen real estate; it's the fact that the embed code loads separately and pauses the video.
yeah, I hear you there, it is a lot more dead space than larger fonts. The buttons are larger, and not exactly for the better on a desktop. And the font has been altered, and arguably to a more difficult to read font. All I can guess is the layout was made for cell phones and no one considered how it would affect the appearance on a PC. I was sort of being sarcastically funny with how I initially typed that.
Another thing I wish could be implemented is a drop-down suggestion list for stuff I have in the smart tab search box, or a return to the reducing view of stuff as letters are typed in. The way it is implemented in 4.9 with the removal of all of it till the full name is typed out in full is just so frustrating to use when I'm not even sure how most of the stuff is spelled, lol.
I just got a bunch of stuff for generation 8, and unfortunately for me it only works in 4.9. So I can't even use the more friendly GUI on 4.8 to make a scene then save it out to render it in 4.9, because some stuff just gets omitted in 4.8 on gen8, I can't win.
I've been rather quiet for the past few months about this new Generation 8 thing, and for good reason. I don't have a lot for generation 8 that I can use is the first side of things.
The other side is I have zero faith that anything in the pro bundles actually works for the same reason that stuff from the Victoria 7 through six months later also did not work on G3F figures. I am well aware of how long it takes to make outfits and submit them to daz, we are talking months after the outfit came out of the 3D modeling program. And the final shape for G3F was not finalized up till the last few days before launch. So there is just no way in hell the outfits will ever work without FBMs for each and every figure shape. I get the feeling that generation 8 was no different with the shape of G8F/V8 not being finalized up to " 'T'-minus seconds" before launch. So you can probably guess how that will work out with stuff submitted before the final shape of the figure was settled on.
(Apollo 1 flashbacks) 
So I've been biting my tongue on the matter. I'm sure eventually PA's will start to have stuff that came out of the 3D modeling programs made from scratch to fit the final G8F shape, tho that will take some time to filter through QA to the Daz Store.
I will inject, simply because it's in the former screen-cap, I do not see any major problems with SY Fantasy Wear, tho my collection of gen8 poses does leave a lot to be desired, lol. I just got that hair and figure last night and have yet to look into them much at this point. The outfit does appear to miraculously be close enough to the final launch G8F shape that it appears to work well with autofollow, and that is far better than Pro Bundle stuff released over six months after the launch of G3F. I think Sickleyield has a time machine or something, lol.
Well, I sort of expected the 3DL mats to be in the base folder with the Iray ones.
Ah, Nope. It's hiding in a sub folder.
I discovered that well after I finished reloading all the maps back into all the surface zones for her
oops.
Perhaps I'll give the regular mats a try, after fixing the lights.
And I was being extremely grumpy because it unrolled that change on me right when I was going through my subscriptions. They even moved the "add to watch later" clock button on the video icons from one corner to the other. Reminded me of how Russian state standards, the GOSTs, are "updated" every few years, with these updates being petty and trivial like that button position (but damn annoying in the long run, for instance, because you have to redo a lot of documentation templates to conform to the updated GOST). Apparently some people are only paid to update stuff, regardless of why and how.
ok, a thanks to 'Zeta' for discovering this, tho I suspect eventually YT will force the new layout on everyone anyway.
if you click your avatar top right for a drop-down menu, there may be a 'Revert back' option.
And I find that 90% is still not that bad reverted back, lol.
P.S. Oh, what is Paul looking at in the latest vid, well, stuff for Arctic Panther (Cat Rawr).
And there has been a bit of chatter about that, lol. As tempting as Epyc and TreadRiper is for 3delight, they just can't deliver the gaming FPS that the i7-7700k does, or the i7-7700x on x299, lol.
As for things nongaming related, Total Rendering Time: 1 hours 20 minutes 33.52 seconds
That was painful for a non-final test render, and perfectly on par with GN's Blender tests.
That is why I did not have a major flood of various lighting and skin shader settings for the former post. Some day I hope to be better off, when the Jeep stops breaking, lol.
ok, things of note. The simulated-ambient distant lights were set to deep-map with a shadow bias of around a CM. I replace them all with the UE2 from the test chamber. Also, the sun and sky lights were also set rather high on the shadow bias, and I knocked them down to a value of '0.1' rather than '1.0'.
OK, I just wander back to the store to see if there was anything good for gen8 poses I could get (that is not over the top sill looking), and I notice something I can tag on to the former chat about my lacking CPU, lol. We interrupt this program to look at a cool shader, And all the bad things I have to say is about the 4GB on the GTX1050Ti and not the shader (there is worse stuff out there), lol. I suppose I should dig up a list of items used.
OK, something to admire, as I dig up the list of stuff that Sparkle was used on. And yes, that is Iray only. A very nice conversion of the former 3delight shader from some time ago.
FWSA Quinn, all stock Iray mats, and, Saffron Hair with stock Iray mats (Sparkle on the headband). Leotard for G3F (not the TJ7 thing), Keyhole Style leggings, A G3F re-fit of Ghawazee Coat shirt *1 (thanks, Fist), Mucho Flow skirt... And whatever Daz Studio uses for no scene lights and backdrop, my Iray skills are still very lacking at best
*1, I'm not sure how the auto-fit-thing does for the regular G2F shirt to G3F figures, I'm using a refit Fisty made.
Now, that does look like a few more options in the Iray set than what I see in the 3delight version promos, tho looks can be deceiving as well. This is not a one-click and be done with it set, as there are a few simple options that can be combined into a very nice looking cloth. And knowledge of what Iray setting does what is not needed for this, it's really simple to use. No need to adjust a setting and walk away for 8 hours just to see what it does (on the GT730), and that is why my Iray skills are not the best, I gave up trying to figure out the Iray surface tab setting, lol.
There are four basic cloth patron types with a multitude of color options. Then there are a few glitter patrons that can be added to the chosen cloth, and the lace transparency patron is a third set of options. Iray cloth is just so easy to set up like that, and I don't need to waste weeks doing spot-renders just to see where maps go in the surface tab, lol. Three selections (or two for non-lace) and get wonderful cloth, thank you is just inadequate for how happy I am with this.
Now I just need to scrape up for a computer that can do Iray in a reasonable amount of time
. And in all fairness, the GTX1050Ti now is nothing like what it was like back in the beta Iray days on the GT730. It is no longer days to get anywhere, tho it is still rather painful at times in other ways. 4GB just is not enough if you want to do more than just single person portraits (with any shader, and newer outfits and newer hair), lol.
ok, some more fussing around with Sparkle shaders
, and it dawned on me after the last render, that there was a note somewhere about GPU memory usage with Iray. I'll need to dig that up tho, don't want to get anything backwards on that.
So, after the final render finished, the GPU hovered around 3277MB usage out of 4GB. Clearly a 3GB or 2GB card is not enough, lol.
Yet the test renders as I was figuring out what to use was a tad higher. And that was without earrings and leggings. So I'm not entirely sure what is going on there. So in any case Here is a mix of FWSA Paloma (and the leggings again) and Izabela7. This time with the Cathy skirt, and Klan hair.
I guess my color coordination "just never was", lol. I'm also not sure I clicked all the correct settings for the Iray skin tone, looking at her promos, I'm sure I got something wrong there. The render took around 45 minutes on the GTX1050Ti, and at least that is far better than days of old.
(EDIT) I am inept
, the sun is almost behind FWSA Paloma there, and I guess there has not been time to work out a shadder update for Paloma on the new Studio 4.9 Iray tinting of stuff.
It has been rather hectic.
Thanks a million for sharing!!! I reverted and wrote them a letter of complaint in the field provided =P
If there is no SSS on the skin (and if there is, I don't see any effect of it...), then it's a ridiculous render time =( What were the settings and lights??
I saw some sort of a helper freebie scripts on sharecg that was supposed to help use G3 poses on G8? Never tested it because I don't have much for G3 LOL
https://www.sharecg.com/v/88560/browse/21/DAZ-Studio/G3F-G8F-pose-adjust-scripts-Legs-Arms-and-Full
Well it's not bad at all, you appear to have chosen pairs of contrasting colours, it's a valid strategy =) You wouldn't believe the colour combinations I keep seeing over the last few years in fashion magazines.
You mean those melt your eyeballs and make you want to smash your brain out with a large gold brick wrapped in a slice of lemon ones?
I surely could use a Pan-Galactic Gargleblaster! =D
Or two...
*kicks at the Sub-Etha Sens-O-Matic that keeps on being silent*
lol. out of all the computer case themes that are black and just one non-gray color, and the hatred some have for ketchup and mustard wires, anything with more than one color is almost alien to me, lol. I myself do prefer ketchup and mustard wires over the random pin-out guess all black wires of late, especially given my luck with modular power supply cables included with stuff of late, lol.
Steam Punk Hide Away lights, how much can I say about that without giving away Dreamlight's settings, hmm. First off, the glass behind AS Sewa was quite complete with diffraction and reflection, so I guess that was most of the time aside from the outfit and hair that was all stock settings for that stuff. Only the figures skin mats were Daz Default, because I was being lazy there.
There all distant lights, a simple light setup that I have seen from a very long time ago when the use of no shadows for ambient and shadow map was preferred over ray-trace shadows. I did make some adjustments to all of that, mostly a swap to ray-trace shadows, and the shadow bias to get some skin texture back. I didn't fuss with it anymore than that, out of being lazy and being more interested in the figure and outfit.
Now if I was to venture a guess, I would say the HD morphs combined with cloth and hair shaders compounded by the glass was probably the major player with render times (and everything else with ray-trace reflection, lol). Swapping out the few dozen distant ambient lights for UE2 mad no noticeable dif at all in spot-render times.
ok, looking at GPU memory usage. It looks like the basic driver stuff eats up quite a bit on the primary GPU, and I've seen that as high as 500MB (half a gig) at times with no daz studio open at all. Here I had closed Daz studio that had the former Iray scene open to flush out caches before opening up the 3DL scene.
Just lingering the former Iray scene was eating over 2GB before closing Studio and the usage dropping to around 350MB.
Starting from scratch, it looks like the drivers combined with the OpenGL interface stuff at up around 700MB of GPU memory. So I will guess there is significant overhead for the OpenGL interface and drivers before Iray even gets involved.
