Daz3D makes my PC feel like a 200 year old piece of crap.

Hello,

i have tried tolerating this for a while now, but i just can't no more.

pc specs:

Intel Core i9-7900X cpu @ 3.30GHz

16 GB DDR4

Nvidia GeForce GTX 1080Ti

Samsung SSD 860 Pro 512 GB

-------------------------------------

the viewport is beyond laggy, even when i barely have any G8M or G3M loaded in the scene. god forbid i put 2+ models in an environment.

it's a nightmare to work with Daz nowadays. rendering is even worse with a grainy result and very long rendering times.

Did you enable your videocard accelaration? Preferences -> Interface -> Current Hardware

I have a 1060 and I have no problem with even heavy scenes.So it is definitely not working properly for you.

Here's some tips that made a HUGE difference for me with viewport response:

1. Render Settings/General/Auto Headlamp = Never
2. Draw Settings/Drawing/Response Threshold (msec) = 5000
3. Draw Settings/Drawing/Inactive Viewport Delay = Off
4. Edit/Preferences/Interface/Display Optimization = Best
5. Use Perspective View when manipulating, since any Camera view is generally much slower, especially if you have a light parented to the camera like a headlamp
6. Avoid using "Point At" if you want your character's eyes to point at the camera. That will slow the camera view manipulation a lot. 

Also make sure you check to see if your GPU is actually being used when you want it to. Make sure it's selected in Render Settings, and monitor it in Task Manger or GPU-Z. If using Task Manager make sure to select Compute_0 render engine instead of 3D. 

There's a bunch of other stuff that can cause your problems. Like making sure there's no driver problems and so on.

Thank you! that did help my viewport quite a lot! and i will try rendering something tonight and i will get back to you when that happens too!

one question though, when you mentioned the task manager stuff, i noticed it was saying GPU - 3D, i have no idea how to change that!

Thank you so much for your help!

To the left of "3D" is a dropdown arrow. Click it, and you can select "compute_0". Task Manager defaults to the "engines" it thinks will be the most interesting and utilized by the average user (gaming, video watching/editing, etc.), but in our case it should default to "compute_0", since apparently that's the GPU engine that CUDA/Iray tends to use, at least on my GeForce GTX cards. That might change with different architectures/generations of GPU's.

hmm whenever i do that, if i close the task manager it goes back to 3D.

thank you very much for your help!

Where are you seeing this drop-down? I don't have it in the Processes or details tabs of Task Manager, and there's nothing in the right-click menu either.

I think it's only for Windows 10, found under Task Manager -> Performance tab, on top of the graphs.

btw, if you want to speed up the Daz viewport, simply put your objects into separate groups, and hide the ones you're not using.  This works especially well for large scenes when you don't care about the background until it's rendering time.

Here's an example, although I captured this on an old laptop that is GPU-challenged.

Ah, in the graphs. Thanks.

Note that not all 10-series NVidia cards are created equal — how much VRAM does your card have? A scene will only render in the card if it all fits in the card's memory, otherwise it will fall back to a CPU render, which will give exactly the same result, but much more slowly.

The exact card driver version is also critical. How recently did you last update it? If the driver is too old, Iray can't use any 10-series cards.

One other thing to note; Windows Update is known to occasionally "update" a perfectly good NVidia driver to a less capable version that doesn't work with Iray. If your renders are suddenly not using your card, and Update Tuesday wasn't long ago, your first suspect should always be a replaced card driver.
