DAZ Studio 4.23 Stops Applying Denoise Filter After Rendering Five Frames

I'm running DS 4.23 and have denoise filter on for my renders.  When I set it to render out to an image sequence of .png files, it will render out 5 frames with the denoise filter applied but then the 6th and subsequent frames will have lots of noise like DS forgot to apply the denoise filters before saving to .png file.   I have to close DS and start it back up and reload the scene each time I want to render the next 5 frames without noise.  What is causing this and how do I fix it?

    Have you checked your log to see what's going on during the process? What kind of GPU do you have? How much VRAM does it have? What version driver are you using?

  • RTX 2060 with 6GB VRAM with Nvidia driver 566.03 game ready version. 

    Here are some lines from the log.

    Essentially, you are running out of VRAM, so your GPU can't be used. And denoiser can only be used on GPU.

    Try if you can reduce the load, e.g. by reducing texture sizes. You can do it manually or use something like https://www.daz3d.com/scene-optimizer

    Also check that your subD level are low. I would say max 1-2. Also you can hide objects not in view of the camera.

    But 6 GB is limited and you will easily run into problems where the GPU will not ba able to handle it.

  • Why can't DS free up the memory?  There's got to be some way to clear the memory without me having to shut down DS and relaunching it again.

    This is an Iray limitation, as far as I know.

    From my experience, there is memory leak in DAZ 4.23.0.1 with NVIDIA driver 565.90 when doing IRay render. I have 24 GB VRAM and I have to restart DAZ after about 300 rendered frames. Each IRay render eats a bit of VRAM and the VRAM is totaly full after about 300 frames. Because you have much smaller VRAM you get out of VRAM sooner.
