title: Creating multiple command pools per thread in Vulkan
body: <p>I am trying to set up a multi-threaded renderer with Vulkan and I have a question about command pools.</p>
  
  <p>Here <a href="https://on-demand.gputechconf.com/siggraph/2016/video/sig1625-tristan-lorach-vulkan-nvidia-essentials.mp4" rel="noreferrer">https://on-demand.gputechconf.com/siggraph/2016/video/sig1625-tristan-lorach-vulkan-nvidia-essentials.mp4</a> at 13 minutes, they talk about how you should make 1 command pool per FRAME and cycle them in a ring buffer.

  <p>Why allocate 3 command pools per thread(one for each frame in a 3-frame ring buffer) instead of having just one command pool per thread and having 3 command buffers from it?</p>
