This is driving me totally insane!

I am working with Iray preview mode open and i am testing different lights on my subject...but then all of a sudden Daz suddenly crashes to the desktop!...in the beginning it used to happen like once...but now its happening a lot more often.

Below i attached a screenshot of the crash report and my graphics card settings I dont even know what to look for or what i am reading since i dont understand none of it. But something definitely aint right!

Hopefully some of you experts might know whats going on.

Thanks.

My specs:

Core i7 CPU 3.20 GHz

16 GB RAM

64-bit

Windows 10 Home

NVIDIA GTX 1070

Well I am not sure but try clearing your cache in DS before loading your scene. Also the error is pointing to the Nvidia Cuda drivers. Try installing the current Nvidia drivers. I was getting this for a while before I found that Nvidia also offers drivers called Studio drivers (Not the game ready drivers) which are designed more to work with Graphic apps that make use of the Cuda cores. Be aware they are not the best for video games but really helps DS.

In my experience, updating the nVidia driver usually help. Also, Check your resource usage. In some instances a scene with some large texture maps can use up your VRAM as well as your System RAM. I noticed you only have 8 GB of VRAM and 16Gb of system RAM.

I did a Google search on your error message and found the problem seems to come up with scenes that don't fit in the RAM of the GPU.

Does this error happen every time you render? Can you render a simple scene without errors? If you remove a model from the existing scene and do a test render, does it work?

This annoyance happens when I am in Iray preview mode with only one character in the scene and nothing else...simple hair. Then I start adding different spot lights one at a time to test the lighting...as I start loading the lights one by one initially nothing happens...until I load the the third or fourth light...BOOM!...crash time!...

I have to constantly save my work every couple of minutes because of this terrible ordeal!...

Rendering itself is not a problem at all...can go on hours rendering very complex scenes without Daz crashing at all...its only when I use the preview mode.

And buying a brand new powerful graphics card with tons of Ram is totally not an option at the moment...

With your video card you really shouldn't use Iray preview mode. It's very resource intensive. I only use it sparingly and I have 2070 and a 2080 in my desktop.

That's a drawback with iray, though. If you want some idea where you are with your scene, you may need to use the iray preview, at least in the small preview window. Otherwise, you're likely to be surprised when you press the render button. Iray lights and materials don't always play well with the normal OGL/CGL preview settings. Unfortunately, working in iray is a lot easier with beefier machines that have a lot of RAm and VRAM. Which is part of why I still use 3DL for 99% of everything I do in DS.

I agree to a certain degree. I use the Iray preview a lot when I am positioning skydomes, HDRs, and large structures... However I try not to do major movements with it turned on.

I use the Iray preview when I have a fully populated scene; which happens often towards the end of a project, In these cases I will turn it on, view the results, then turn it back to Shader rendered. Make changes, then turn it back on.

Even with the dual 20x0 GPUs, moving objects around can be pretty choppy in Iray preview. (I think that Iray preview will only use the active GPU, but I don't know for sure.)

I was really never happy with the 3DL results I would get, I just wasn't skilled enough to harness it. So I am much happier in the Iray days.

Turning the preview on and off makes sense. I don't think the IRAY used to be quite so VRAM-intensive. From what I've read, we are seeing negative progress in that department. There are older videos on yt showing smooth use of IRAY preview on less powerful cards.
