Vulkan 1.3.255 is released with a new vendor neutral extension VK_KHR_cooperative_matrix for tensorcore-like fast matrix multiplication, which could possibly be used to speedup nnedi3. A basic 16x8x8 fp16 coopmatMulAdd is enough. And according to some perf stats I found elsewhere, a 2x to 3x speedup could be expected.
But first, this had to be hold until AMD implemented this extension in their Linux driver (or maybe radv will overcome and implement this first?).
