DLSS5 video upscaling is lightning fast—could multipass x2 loops replace AI upscalers?

Testing DLSS5's video upscaler, the author found it completes an x2 upscale of 15-second clips almost instantly, improving small details and fixing shadows—less powerful than typical AI upscalers, but far faster and without the usual upscaled look. They propose iterating multiple passes of x2 upscale-and-shrink to accumulate quality gains while keeping the speed advantage, and are asking the community whether this multipass workflow could become a practical alternative for local video upscaling.
