ComfyUI Dynamic VRAM cuts OOM errors

ComfyUI released Dynamic VRAM to defer physical memory allocation until tensors are needed during inference. The update prevents weights from hitting the OS page file, allowing low-resource GPUs to run larger models without crashing.

// ANALYSIS

This optimization effectively "downloads more RAM" via a fault() API that ensures only active tensors occupy physical VRAM. By reducing reliance on slow swap files, it makes high-end local inference accessible to mid-range GPUs.
