While this is 100% true, wasn't there a version of DLSS included with one of the Control updates that ran exclusively on the shader cores? I seam to remember one of the DF videos talking about it, and it was basically the first implementation of DLSS that wasn't the smeary mess it was at launch. And it was still much faster than native rendering.RTX GPUs even have dedicated ML hardware that accelerate these INT8/4 instructions, the output from TCs for these kind of tasks is not only much higher compared to shader cores, they also won't impact gaming performance as much as on say RDNA2 without dedicated ML hardware. That is why DLSS upscaling is so extremly fast (0.8ms on a 2060 at 1080p) and without TCs, running on the shader cores, it would be much slower.
