    Hello,
    I'm running a BOXX Apex workstation with 4 RTX A5000 GPUs and i'm looking at the render console and the GPU load using GPU-Z and I noticed when rendering the computer will send a bucket to each GPU to process, but it waits for all of the buckets to return completed before sending out any new buckets. If one bucket takes 10 seconds and the other take 50 seconds, i've got a bunch of wasted GPU time. Am I missing something? This seems really inefficient. Am I the only one experiencing this behavior?

    Thank you

      Hi Larson Monkey,

      I do not have a BOXX workstation, nor can I reproduce this here.
      This is not something I'm supposed to handle here.
      Please get in touch with Tech Support.
