Fed up with Iray and looking for alternative (Rant inside)

Iray is money and resource hog utility. A simple scene require almost 3GB VRAM which is insane. Almost all low and medium GPU became useless specially low VRAM GPUs. Also other GPU not work. Also CPU denoising not work.
ALTERNATIVE is badly needed.
My hardware Nvidia GPU is currently cannot render Iray and I am looking for Iray alternative.

My issue with Iray is that it takes a long time to render, well compared to 3DL that is. As far as I know the VRAM problem you mention above is unrealated to Iray rendering. It's just how much your GPU can hold in v memory. So if your scene doesn't fit your VRAM, you'll have the same problem regardless if you're rendering in Iray or 3DL.The only solution is to render smaller (less heavy) scenes or optimise your scenes by reducing texture sizes, or get a card with more VRAM.
Depending on what you're looking to do, you can get some excellent results with 3DL.
Even a primitive e.g. cube, plane etc. without any texture I cannot render with Nvidia GPU. CPU render is possible but without denoising feature makes it useless too.
Currently 3DL is my only render engine for that PC but sometimes 3DL is very slow compared to render engine with denoising feature. I am also strugling to mix Filament with hair etc.
Reality
Poser 12
Poser 12 probably does not support denoising. Am I correct?
You can also denoise *after* the render with intel denoizer for instance.
Accordng to the promo page it does include AI based noise reduction, and has an effects palette for denoising and other effects. No idea how they work.
One thing to remember though is that Poser 12 doesn't support Genesis figures at all since the switch to Python 3 means the DSON importer plugin doesn't work anymore.
Not sure what you are even talking about. Only the very lowest end Pascal cards have less than 6Gb of VRAM (3gb 1060, 1050ti, 1050 and 1030). So you seem to be talking about very old HW not recent generation low to medium tier GPU's.
I have a 6GB 980Ti (after running a long time on a 4GB 660 card). I use this tool a lot:
It helps reducing the size of textures, dialling down SubD, and removing unneeded textures for background figures. Also, a good idea is to make sure you tune down Subdivision to base unless the figure is prominently featured.
I also use an external render farm for final & larger scenes, which is cheaper than buying the cards & upgrade the computer & pay the power bills: http://www.jacktomalin.com/iray/
However, if your card can't do Iray (I guess it's non-nVidea), and you are looking for "realistic" renders, you could try Reality (there are several plugings, and you have to dowload the render engine), a very good one is this:
But you'll have to adapt the textures/materials to use Reality unsing the plugin, Iray doesn't work for Reality.
Alternately, you could use Blender/cycles for rendering. There's a free plugin to get the scene over from DAZ Studio to Blender; I don't know how much work you have to put into conversion of the materials from Iray to Cycles.
Denoising is easy. Render at 2x and stick it through Gimp/Photoshop. Which half the time you are going to be doing anyway.
Isn't the big Poser vs Daz issue, G8 and HD morphs?
No, Poser actually supports the HDmorphs on genesis 1&2 but not the dual quaternion rigging on 3&4 and bits vanish in it as well even after converting to triax in D|S and saving a cr2
My GPU was working till yesterday without any problem. This GPU is one of the best selling GPU at present, or may be it is the best selling GPU ever. Currently available at Amazon with tags Amazon's Choice, more than 5000 ratings and most of them are 5 and 4 star.
I know it wont work anymore from today because Iray upgraded with RTX priority and due to less than 4GB VRAM this GPU is now incompatible with Iray. New Iray version with 3000 series supports are awsome enough to justify withdraw Iray render for low VRAM GPUs.
Iray or Cycle etc. like engines are faster than 3DL for me for some scene due to realtime denoising and from today Iray is abandoned that GPU, though Iray was fully functional till yesterday with my present GPU.
In case you updated your dAZ version, have you nVidea drivers? DS 4.14 needs a newer driver version.
Current installed Nvidia driver is 457.30
Thread feels like a Troll, but what do I know. More screaming into the darkness...
Iray is pretty comparable to other renderers in speed from my limited testing. I've only used iray and arnold though. Results seem comparable.
Now, viewport efficiency on the otherhand. Comparing the ability of the viewport to update the scene in Iclone, Daz3d, Blender and Maya - Daz3d is absurdly slow. I can get 30 frames per second in iclone at it's most taxing settings with global lighting and all the bells and whistles enabled, and barely 1 frame per second in Daz studio at it's most minimal settings. That's not a hardware problem. That's a software problem.
Maybe it's worth complaining about? Thing is, the best response you will get is to "tell it to someone who cares". You will be directed to speak to the nearest wall. I may well be speaking to one right now.
The people who know, don't care to help. The people that care to help, don't have a clue waht they are talking about.
Filament?
your card died?...only one?, I've burned 3 PC's and 4 Expensive Graphic Nvidia Cards since I do 3D that is 14 years and counting.
welcome to the expensive world of 3D.
I agree it is frustating. After 4.11 IRAY , and now the new DAZ 3D software seems to force upgrades to more intenstive drivers and software requirements and increased reliance on GPU I could render much more, much faster 2 years ago, than I can now, due to the increasing memory intensiveness of IRAY. I just render the same 2 characters, so the differences are increasingly noticible. Used to be able to render 6 figures in a scene with an environment. Now I have to optimize everything to please the software. Newer isn't always better.
Galaxy, I thought your father was helping you get a new computer. What happened?
Say what it is because your vagueness is telling me that it is some low end card.
I'm thinking it was an older now not supported card. It was probably great several years ago.

Now I have two PC. New one is expensive and working fine. Facing problem with previous PC.BUT ONLY with Iray. Only Iray GPU render is not working.
I had nearly the same problem since yesterday (Update to 4.14.)
- crashes occurred on a 2080ti with failure log entry about "an illegal memory access was encountered, CUDA error code: 700"
- sometimes at 100 iterations sometimes at ~ 9000
- The only thing what solved the issue was to uninstall the current Nvidia GameReady driver and switched to studio driver.
- now everything seems to work as before (keep fingers crossed)
I know you know it is some low end card, because I know you or your expertness. However fact is Iray just withdraw suppot for a GPU which is previously supported and currently available to purchase everywhere and even while other GPU render engines still working for that card.
Not true, I have a 2019 or 2020 year model PNY GeForce GTX 1650 Super 4GB and well you can see from the name it has less than 6GB RAM.
The Luxus plugin from what I could find was for Cararra and not DAZ Studio. It was once sold in the DAZ 3D store but isn't anymore.
The Luxus plugin, like Reality plugin for DAZ Studio, may even be released as source code now. Does anyone know if the Luxus plugin source ccode is released & if so where?
Not died, working with other render engines. Iray just withdraw support for it suddenly while it is available to purchase everywhere. Yes it is expensive world of 3d, on top of that suppose a GPU price in USA $300 then I need to purchase it $600-$800+ (converted price).
