Is mesh smoothing performed by GPU or CPU?

Thanks in advance

I am considering buying a new GPU if this will speed up this operation depending on where the computation is done.

I already performed a search in the manual on the terms mesh smoothing and nothing came up hence the question.

cheers

    smoothing as far as Interface response?
    Possibly, it depends on your current card vs. new card, some newer cards are not necessarily faster than the older ones especially on motherboards a few years old with older connector types.

    rendering in 3Delight?
    No benefit with GPU upgrade of any type. The process is entirely CPU and RAM

    ok thanks for the reply.

    no - I don't render with daz's engine. I only use octane which is entirely gpu based. still not sure though if mesh smoothing is done on the cpu or gpu

    My understanding of Octane is it's strictly a GPU affair, your CPU is not being utilized but I don't use Octane so I couldn't be sure.

    hi

    yes, correct, octane is strictly GPU. Octane has noting to do with this thread really. I just mentioned it incidentally in response to another response which seems to have confused things now. I am asking about whether or not mesh smoothing in daz is implemented via the cpu or the gpu.

    I don't know if smoothing is done on the CPU or GPU; my assumption would be CPU, though. You could probably suss this yourself using a CPU+GPU load monitor and watching what happens when you enable smoothing with really high values (e.g., set both smoothing and collision iterations to 50 so it takes a while to calculate).

    That said, the rendering engine is moot as smoothing is done to the mesh before it is exported to the rendering engine. The rendering engine doesn't know anything about how Studio smoothed it; it just sees the final resulting mesh.
