CPU heavy usage during IRAY Render?

jas_va_26

So recently (Since the large holiday sales)  I picked up several enviornments and characters that are based on G3 and Enviornments that use IRAY textures.  When using these scenes and assets, I have noticed D3D uses a solid 40% of the processor when rendering, even though it isn't selected for use.  The only item selected for rendering under the advanced tab is the GTX970.  Is this normal behavior?

Yes it is from what I can tell. The log file for Daz should give you a better read of what is actually happening. It can be found at C:\Users\%username%\AppData\Roaming\DAZ 3D\Studio4\log.txt

Or, from within Daz Studio: Help -> Troubleshooting -> View log file...

Nice, I had no idea that was there haha.

Any idea what I might be looking for in the log file to say why CPU is being so heavily used all of a sudden?

It's possible you have exceeded the vram capacity of your video card. If so the render will fall back to cpu regardless of settings. If you are checking cpu usage at the beginning of the render, you will see relatively high usage while things are set up.

if you don't already wait, wait until the progress bar shows some progress (>1%) before checking.

You will want to look for the IRAY lines in the log file. They will be seperated by CPU and GPU (CUDA). Look for CPU lines that have a lot of data. It won't tell you exactly what is happening but you can usually tell that it either ran out of GPU memory or that the current process cannot be done on the GPU. Also the initial setup will use the CPU a lot to create the shaders etc to pass to the GPU.
