Daz Why are renders taking so long on Daz3D?

[Enough]

Hey, I recently started writing and rendering for my game, and I am not sure exacly how to understand Daz3D render progress.

When i start render after few seconds (about 10-20) i see first preview of render, few seconds later it started looking better (less blured), then nothing changes for like 40min.


Renders in low resolution( about 800x600) took like 1h, right now with 1920x1080 I don't know what I am waiting for - (it's just test of environment without even using proper female character) because render on preview already looks fine

What am I missing? Is there something what I should disable / enable to improve rendering time? Maybe my has already few years (i7 4770 and gtx960), but still I would expect to DAZ3D works faster.

If DAZ cannot load the scene into the graphics card memory (VRAM), it will not use it for rendering; instead it will use your CPU and make the rendering time much longer.
With your GTX960 that must have 4GB, it's normal that the scene won't fit, and I guess that's your problem.

To check it you can use programs like GPU-Z and see if your GPU is being used or not.

If you look around the forum there are several posts about this and possible solutions (reduction of textures, rederderizing the stage and characters separately, etc...)

mgomez0077 You are right, my graphic card doesn't give a fuck about it

Thanks for advice, I will try to find some other posts on this forum

You're welcome.

Here's a thread from a user with your same graphics and the same problem, maybe some of the answers can help you... although basically it's about "optimizing" the scene to fit in the VRAM, or reducing the number of elements, or rendering the scene and characters separately

i had to make the same experience... Thats why I render without backgound..
My GTX 970 4GB ( actually 3,5 GB ) fails in rendering Genesis 8 + Background and my CPU takes over ..
It takes between 1-2 hours for simple scenes, really frustrating

I'm gonna wait for RTX 3000s, like 3070-3080.. till then, writing story and getting into RPG MV / Ren'Py

I have 2 x 1080Ti and some of my scenes also take 1-2 hours, and some more, it all depends on the complexity of the scene, materials in it, light, etc, LOL

i dont get this, so does the scene take ~930MB of VRAM GPU to render ? but cant handle it and CPU takes over ?
Even with CPU taking over and my GPU in inle mode, GPU Memory Usage is at 90%

so confusing

That's just what the geometry consumes, the consumption value of the textures will be higher
You can check it by looking the log in the menu "Help" > "Troubleshooting" > "View Log File"

What I don't understand is why it uses 90% of the VRAM if the graphics card is not rendering
Do you have any other applications open?

The usual things, chrome/yt, but that take about 4-5% GPU Memory..

so i tried it again, it says "out of Memory" in log somewhere.. see log

definitly not enough VRAM

You can use

and reduce the textures by half.

i hope it deosnt changes the textures forever.. should be only temporary right, like only for that "scene" ?

EDIT: after using Scene optimizer GPU takes over, but somehow whole systems stutters then, like the RAM is full.. i guess need 32GB RAM ( only have 16GB )

thx for your help ! i am just gonna wait for rtx 3000, enough time for story and learning ren'py and a bit more experimenting in daz3d.

 

[Porcus Dev]

You have to reduce the textures by half, save the scene and reload it to notice the difference (and no, the original textures are not overwritten, the reduced ones are saved in a separate folder)

If you're short on RAM, Daz will give you an error and shut down... I don't think that's the problem if you have 16GB (I started with 8GB and in big scenes Daz would close down; I upgraded to 16GB and never had that problem again; I currently have 32GB).

As for buying a new graphics card, my recommendation is that, whatever it is (1080TI/2080Ti/30xx), it should have 11GB of VRAM, LOL

Be sure you have enough virtual memory. If Daz fulfill your RAM, it will automatically fallback on CPU.
