You should read Nvidia's paper, check page 40 of this document: https://www.nvidia.com/content/dam/...ure/NVIDIA-Turing-Architecture-Whitepaper.pdfHonestly, that can be tested now just by turning off AA and looking at performance, since DLSS just removes AA from the CUDA cores onto the Tensor Cores, it's practically the same thing, running a game with AA disabled in terms of performance.
From my understanding, DLSS renders only half the samples in an image, and then uses DL to fill in the missing unrendered pixels. You can think of it like PS4 Pro checkerboarding just with a smarter algorithm.
This would not be the same as turning off AA as with DLSS you are only rendering half the pixels, so performance should be improved (minus the cost of the DLSS, but that should be less than the brute force approach).
You can also check this article, which gives a good overview of the technique with performance and quality comparisons: https://www.techspot.com/article/1712-nvidia-dlss/
