Optimize performance

Setup to reduce the CPU / GPU usage according to your environment and purpose.

Check the frame rate

Turn on Settings > Performance > Show frame rate to display current frame rate at the bottom of the window.

Use GPU

MocapForAll uses AI to estimate a person's pose. AI calculations are often faster on the GPU than on the CPU.
If you have a GPU, it is highly recommended to select GPU_DriectML from Settings > General > Run DNN on.

Select from multiple GPUs

If you have multiple GPUs, you can also choose which GPU to use by Settings > General > Run DNN on > GPU.

Should I use TensorRT?

When using a GPU, you have two options, GPU_DriectML or GPU_TensorRT.
TensorRT is difficult to install, takes a long time to load, and has little reward. So, it is recommended to use GPU_DriectML in many cases.

  • GPU_DriectML:
    DirectML provides GPU acceleration on DirectX 12 capable GPUs. Examples of compatible hardware include:

    • NVIDIA Kepler (GTX 600 series) and above
    • AMD GCN 1st Gen (Radeon HD 7000 series) and above

  • GPU_TensorRT:
    TensorRT provides GPU acceleration on supported NVIDIA GPUs. To use this, you need to install CUDA, cuDNN, TensorRT, and Appendix4_TensorRT_mode.

Select capturing mode

From Settings > General > Capture body, you can choose what to prioritize.

  • In many cases, Speed is recommended.
  • Speed+ is recommended when using a PC with low performance such as a laptop PC or when using together with a very heavy VR application.
  • Use Precision mode when you want to capture motion precisely such as for movie production. You need to install Appendix1_Precision_mode.

Reduce drawing

With the following settings, you can reduce the drawing on MocapForAll and reduce the CPU / GPU usage.

  • Select Empty character in Settings > General > Character.
  • Select Minimum map in Settings > General > Map.
  • Set small value (30% for example) and turn on Settings > Performance > Set screen percentage to,
    or turn off Settings > Performance > Render the viewport

Limit the frame rate

Set the target frame rate (30FPS for example) and turn on Settings > Performance > Limit framerate to:.
MocapForAll runs up to this frame rate.
