Oh, so he's just talking about DLSS3 features, gotchya. I thought DLSS 1 performance improvements are also frame generation but I see now thats different
DLSS is upscaler. Game is rendered at lower resolution and then image is upscaled in a bit smarter way than simple "stretching".
More precisely, DLSS is a set of models that use AI to interpolate an image. This interpolation can take many different forms:
Interpolation can be used to take a lower resolution image and upscale it, which is the main feature of DLSS.
You can also use DLSS to take a high resolution image and scale it down, with less artifacts, as a type of antialiasing. This is DLDSR.
You can also use it to take information from an image, combined with motion data, and interpolate how blocks of pixels might change into a new frame. This allows you to generate intermediary frames. This is Frame Generation.
You can also take a very noisy image, composed of discrete dots, and interpolate how neighboring pixels should look. This is Ray Reconstruction.
