Environment (please complete the following information):

  • OS/OS Version: Windows 10
  • Source Version: master
  • Unity Version: Unity 2021.3.17f1

Describe the bug
BlazePose when in Play Mode, runs around 10 fps (not consistent). It does this even on high end windows systems. This was tested even in older commits of master (dating back 1 year)

To Reproduce
Steps to reproduce the behavior:

  1. Open BlazePose scene
  2. Run Scene
  3. Check Stats and Profiler for performance

Expected behavior
Windows performance should match as it does for Mac (with similar specs)

Hi @SusheelNath,

On MacOS, BlazePose runs on the metal delegate. On Windows, however, it runs on the CPU, even if you select a GPU option because the TensorFlow Lite does not support GPU acceleration on Windows.

If you choose the XNNPack option on Windows, it works much better than the CPU. However, it will still be slower than the GPU delegate.

Hi @asus4,

The above works. Thank you.
