What is DLSS? Is it new AA ?
From what I understand it's and advanced method of upscaling/supersampling using deep learning (it's stand for Deep Learning Super Sampling after all) which is supposed to improve framerates without sacrificing image quality (or even enhance it if you believe Nvidia). When you choose 1440p in your game and activate DLSS, the game actually runs internally in 1080p and supersample it to 1440p, same thing if you select 4K and activate DLSS the game runs internally in 1440p and super sample/upscales the image to 4K, at least that's how I understand it, I think it also is a kind of AA too i'm not sure.
Problem is only 3 games support it right now (Battlefield V, Metro Exodus and FFXV) and in BFV and Metro it looks far more like a blur filter than anything, only in FFXV does it seem to look better than regular 4K+TAA but that's because the TAA implementation in FFXV is quite terrible and blurry.
Here you can see how terrible it is right now at least :
And here's an article that explain the technology far better than I ever could :
