The Leather Jacket will use every marketing trick he knows but he's not fighting AMD in this space anymore, i think AMD are just keeping their foot here because there is still some revenue for them and to see if they can turn it around without bankrupting themselves.
Jens is not going to make a 2080TI £500 or less with Ampere, neither are AMD, except in consoles where you get a whole gaming box for that, AMD don't care, they will take their $150 for every console sold, probably more than that now.... for doing literally nothing, Nvidia can't compete with that, Nvidia are now fighting to keep PC gaming viable because that's all they have, even the Nintendo Switch replacement is moving to a Samsung / AMD SoC.

Anyway.... on DLSS, games in 1080P look like milk on my 32" 1440P IPS screen, that is they look washed out and blurry.
One of two reason i don't think DLSS is the magic button that gives you native resolution gaming with lower resolution performance, one it depends on developer implementation and two not all screens are equal in upscaling to native resolution.
