Frame generation is the only real odd-one-out here, the rest are using basically the same technique under the hood. I guess we don’t really know exactly what ray reconstruction is doing since they’ve never released a paper or anything, but I think it combines DLSS upscaling with denoising basically, in the same pass.
It’s both. Nvidia just started calling everything DLSS, no matter how accurately it matches the actual term.
Image upscaling? DLSS. Frame generation? DLSS. Ray reconstruction? DLSS. Image downscaling? Surprisingly, also DLSS.
