A user reported a severe performance issue when queuing multiple video upscaling tasks with Minimax H3 Latent Upscaler. The first generation runs smoothly (60-180s), but subsequent generations see initialization and step times spike to over 1000 seconds. The user is asking if others have experienced this or know of a fix.
