  • Vray gpu buckets vs progressive

    Hi
    Just a fast question, since i'm going to do some test and i don't want to push over the top My 2 2080ti, which one is less stresfull vray gpu buckets or progresive for the hardware? or do You think is the same?

    Thanks in advance

    Hey Luis!

    Progressive mode is a bit faster at the moment, and uses less GPU memory. The difference shouldn't be massive, so feel free to use whichever you like
    We are working on improving bucket mode at the moment to be faster and efficient on memory.

      Whaaaat? I've read somewhere (in documentation perhaps) at some point that GPU shines in progressive mode but somehow I could not accept it in my mind. After all this time using buckets for rendering...
      Some time ago I did some internal testing and I didn't notice any significant difference. Probably it may vary a lot in different scenes.

      Although, how could it be more memory efficient ? I noticed that progressive mode almost always fills up more VRAM. (I am going to double check it soon for sure).

      After all, it makes so much sense that GPUs are faster in progressive mode due to their nature, being so good at parallel computations.

        Hey Karol.Osinski

        The differences shouldn't be massive, feel free to use whichever you are used to. Like many other settings, V-Ray gives you the choice to work the way you like, both bucket and progressive modes should get the job done.
        Bucket mode is still better in DR or multiple GPU scenarios, and we have plans to improve it on both speed and memory usage.

        While it uses more GPU memory than progressive, Bucket mode is more efficient on system memory for high resolution rendering as it writes the rendered buckets to disk. I'm doing my own tests right now for the GPU team in this regard, but let me know if you find something different.

        Best,
