Daz PC Hardware Requirements

n.aspros123

Which PC parts in terms of CPU, RAM and GPU make Daz Studio run at it's highest rendering performance and shorten render times?

Is Daz Studio CPU or GPU load dependent or a combination of both?

Does Daz Studio require more CPU cores like a 7900X/6950X/9950X(release Aug 2024) or can it run on a 7800X3D high cache CPU which is optimised for gaming?

If you're rendering with Iray under Windows, your GPU can be used for rendering. That is, providing you have a recent nvidia GPU with enough VRAM for your scene to fit there (RTX card with 12GB VRAM is usually recommended, 8GB is considered a minimum nowadays).

In other cases you'll be rendering with CPU. Iray rendering with your CPU is much, much slower than rendering with your GPU.

You'll also need a good amount of RAM or your system will swap and be slower.

I render using Iray and currently using a GTX 1080ti and 16GB RAM. I'm waiting for the new AMD CPUs particularly the X3D ones as I do VR sim race. Then I'm looking at either RTX 4090 (out now), 5080 or 5090 when the release and 64GB DDR5.

IIRC the GTX 1080 ti has 11GB VRAM. It's not an RTX card which means part of the VRAM will be used to emulate RTX features, but that's still not bad.

16GB of system RAM is not much though.

 

Unless you create big scenes which won't fit in your card VRAM, you probably won't use the CPU at all for Iray rendering (you can render with both CPU and GPU but that doesn't really bring much), so having more CPU cores won't help with rendering performance.

Core count and CPU speed would matter if you plan to do 3DL rendering though, as it uses the CPU and takes advantage of multiple cores.

How to check that Daz is using the GPU?

Well first you can check in Daz Studio log what devices is listed as used.

Task manager doesn't show CUDA activity (which would correspond to rendering) by default. IIRC if you click on "GPU 0" to display the various GPU-related graphics you can then select "Cuda" as a display option.

A lot of people also use GPU-Z to monitor GPU activity.

Done a little searching for this, I unticked CPU.  https://www.daz3d.com/forums/discussion/462331/daz-not-using-gpu?srsltid=AfmBOoqLlt7Pb3ZcbqCY3TBXOwICeiVYtX8lhOU95n71ZtiDyyY12bjo
