I've been doing some tests on my 3090 and the bundled CoD game, with DLSS 2.0 and raytracing at 4K.
It's still as terrible as it has ever been on the high contrast near horizontal and near vertical borders, like from windows and doors.
Horrible under sampling of those edges and terrible staircasing aliasing artifacts (and that with highest quality DLSS)
It immediately throws you out of the illusion you are looking at a high resolution rendered game.
For me a no go, the 3090, is fast enough to not use DLSS, occasionally it dips below 60 FPS at true 4K, but I prefer that to poor rendering quality.
