A developer tested Minimax video generation times on an RTX 3090 (64GB RAM) using ComfyUI (CUDA 13) for an 8-second, 0.8MP video.
Results showed base workflow took 850s. Using Spectrum reduced this to 520s (a 40% decrease). However, adding Sage Attention (SA) yielded no further speedup, prompting the author to ask the community for troubleshooting advice.
