I still fail to see how upscaling is more than just a crutch when performance is lacking for the desired resolution and graphics quality. It's great for low to mid range gaming, but I don't want it with a high-end GPU.
DLAA is a different matter, though. It's more of a downscaler than an upscaler, as far as I understand.
Then you should probably read up on DLSS, because it has built in anti aliasing and sharpening which is why it replaces other AA methods when enabled.
Meaning, DLSS Quality running at 1440p like I use, will look better than 1440p native, while boosting performance by 50-75% on top. Win/win for most gamers.
DLAA is everyhing DLSS is, just without upscaling, uses native res and just improve the image quality. And this is why native res gaming don't matter anymore, because native res with 3rd party AA on top looks worse. TAA is terrible just to name one inferior solution.
DLAA is the best anti aliasing method today and will work in all DLSS games. DLAA is part of DLSS presets now.
Still boggles my mind that some people think DLSS is only for improving performance while sacrificing visuals, this is not true at all. Mostly its AMD users that think this, probably because FSR is mostly doing this and looks mediocre in comparison, which is probably why they hate DLSS too and upsclaers in general, even tho they don't know that DLSS works far better than FSR, without the massive shimmering and artifacts that FSR produce, especially true when you actually move, instead of looking at still photos.
I hated FSR on my Radeon 6800. I love DLSS/DLAA on my 4070 Ti. AMD is years behind on upscaling. Simply too many problems with it (mostly artifacts and shimmering) and it looks like AMD hit a wall in terms of improving it.
AMD needs to vastly improve FSR going forward, maybe they should go the hardware route like Nvidia. More and more games rely on upscalers as AA now. Upcoming PS5 Pro and next gen Xbox also will rely on upscalers. Upscaling is here to stay, game devs embraced it and every single new AAA games has it built in. It is even enabled as default, also in AMD sponsored Starfield. Sadly it looked crazy bad and RTX users installed DLSS/DLAA mod on day one which beat FSR2 with ease
AMD users were better off enabling CAS Shapening in the game, sadly performance takes a hit.
