Use of GPU in DAZ

Does DAZ use GPU to accelerate the rendering ? Will a good gaming graphic card help improve the rendering in DAZ studio ? If so, which Graphic card in reasonable price range has proven to be good ?

    The graphics card has no effect on regular DAZ Studio renders* but a good one will reduce lag when you are doing other things (like loading and manipulating items in your scene).

    *However, if you're using the Luxus or Reality plug-ins and rendering in LuxRender, the GPU can affect render time, I believe.

    Lux Render (Reality and Luxus etc) use OpenCL and yes it does decrease render times but not all settings can be used when in Hybrid CPU/GPU render mode. ATI seems to have better OpenCL performance.

    Octane uses Cuda I believe which is Nvidia

    that statement is only true when comparing CPU to GPU and output quality
    If you have a high end graphics card in a low end CPU you will get the benefit of speed when rendering in GPU over CPU
    If you have a high end CPU and a mid level GPU you might not notice less of that or in some instances no benefit at all.

    I do mostly Toon Shaded Flat tone characters with the help of PWTOON or built-in Toon Shader. I rarely use textures.
    Do you think Reality Plug-in is of any help ?

    I am definitely looking for a way to improve the rendering time. DAZ has beautiful characters, shaders, rendering quality but Rendering Time is a BIG spoiler. It's so difficult to stick to the deadline in this competitive environment with DAZ Renderer.


    Any help in this regard is welcome. Somebody suggested to work on the Shading Rate and Bucket Sample. It has helped a bit. But still need faster rendering speed to meet the deadlines.

    LuxRender (via Reality, LuxRenderDS or Luxus) is not a speed solution over 3Delight when working in Daz Studio.

    you could try turning down the setting on your 3Delight panel and experiment. Bucket size is the amount of RAM that is assigned to a core when rendering. if you have two cores with a high bucket size you may experience slightly faster rending however if one of the cores encounters a section that has more computations than the rest of your scene it could get stuck for a while computing the calculations while the other core zips through the rest of the render. A lower bucket size with multiple cores generally gets through this situation faster because the other cores are working smaller areas while one or two cores gets tied down.

    keep in mind
    Displacements+raytraced shadows = rendering speeds akin to molasses uphill in cold weather.
    When light is required to render a shadow you slow down rendering, especially if the shadow is cast over multiple surfaces.

    When transparency encounters light you slow down rendering (think Hair models, which will get worse if the hair has a displacement)

    When light meets a shadow yet to be determined because it's based on a displacement you slow down rendering considerably.


    Have you been able to use open GL rendering, its not the best but if you want quick and free that's about as quick and free as it gets.

    I'd agree that LuxRender may not be the best choice for you. There are things you can do within the standard 3Delight render engine that will help...shading rate is one of them. More advice from various people can be found in this thread: http://www.daz3d.com/forums/discussion/19384/

    And if you want to speed up the process of rendering hair (often one of the biggest contributors to a slow render), there's some information on that in my hair tutorial (linked in my sig).

    Looks like my ToonShader ( PWTOON ) does not work with OPENGL.

    the other stuff will apply and I'm reading Scott's hair tutorial now (good stuff!)
    rendering hair is the most common bottleneck in speed on rendering human figures because there are so many calculations involved.

    What kind of RealTime Rendering Engine ICLONE uses ? The rendering is so quick !

    I love ICLONE rendering speed, but I love DAZ Studio Toon Shader !!!! So difficult to choose.

    I think iClone uses OpenGL.
