Mac users, don't forget to upgrade your torch package for significant performance gains

for my ltx 2.3 workflow on M3 Ultra:

  • torch stable 2.12 - 180 it/s
  • torch nightly 2.13.0.dev20260511 - 30 it/s

Be aware: the newest nightly 2.13.0.dev20260520 doesn't work in comfyui. it only renders black images for me. So I am recommending the slightly older version.

Depending on your environment, update with something like:

> pip install torch==2.13.0.dev20260511 torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cpu
