Crutches that are better IQ than TSAA?
That's subjective rather than objective, far from a unanimous opinion, and I for one hate DLSS because it's a smeary, incoherent blur in motion on a fast enough display like OLED or good high-refresh rates screens.
In some games, blur doesn't matter, but I have always turned off motion blur no matter what. I loathe it in games.
Some games implement DLSS better than others, and a good DLSS implementation can be good enough that I will actually tolerate it for the performance gain.
There will always be artifacts, and it's always easy for me to spot the low-resolution jaggies of the actual render resolution; You can't see them easily in static side-by-side comparisons, and you can't really see them in Youtube videos because of the compression.
Raytracing makes the artifacts even more obvious because the raytracing generates a noisy image and the size of the noise is exponentially larger the lower the sampling resolution gets. You only see the noise in motion, because the denoiser can hide the worst of it within 3-4 frames. Only a moving image is constantly generating virgin reflection/shadow/ambient information that the denoiser has no prior frames to deal with.
One thing we can always agree on is that when DLSS 'Quality' is used for 4K, it's being rendered at 1440p because that's an objective fact. IMO that makes it a 1440p card because you can upscale or downscale that to literally any arbitrary resolution you want, using any technology you want. 4K, 5K, 8K? Who cares? It's still a 1440p render and if you want DLSS's temporal AA, then use DLAA.
