Digital Foundry came to similar conclusions as Hardware, for now DLSS 3.0 is basically fake frames unless you are driving a car in a straight line for a long time. If that was not enough, it increases your input latency by a wide margin since it holds two frames to compare and come up with that frame in the middle that it's supposed to generate.

I actually played Miles Morales with and without DLSS 3. Without pixel peeping and doing a bunch of extra stuff, I can honestly say I never noticed anything that made me feel like FG was causing rendering errors. Did it look better? No. Did it look or feel at all smoother? On the 4080, at maxed out settings and 4K, yes. I think it did. I imagine there's a sweet spot between a minimum real FPS requirement and a maximum where DLSS 3 feels best.
That's important to understand. In normal use, without going to great lengths, it's difficult for even a professional graphics card reviewer to detect the errors. It's not that they don't exist, but it may very well be that they don't really matter.
If you listen to the lengthy explanations given on the problems with DLSS3, what it all devolves to is that you generally have to carefully look for rendering problems, sometimes going so far as to intentionally do things to create the problems (like moving the mouse around really fast). It's a pain in the rear to test, as you need to capture 4K at 120 Hz basically. Some of the rendering errors are quite bad, but the inconsistency of the problem means the actual gameplay experience may not be affected all that much.
I'm still not sure what to actually think, having tried DLSS3 in several games now. For me, it was fine. I could enable or disable it and not really notice much of a difference — again, without putting in a lot of time to test and try and figure out precisely what's happening on a frame by frame basis. But the 4090 and 4080 are already so fast that perhaps it's less of a problem. How will Frame Generation feel on a future RTX 4050? I suspect a lot of the problems discussed by others will become far more noticeable. That's not going to be a good experience, in other words.
But ultimately, I do like having choice. Maybe some games I decided I like the FG effect, others I don't, some run fast enough without it, etc. It's the same reason I like that Miles Morales also supports FSR 2.1 and XeSS alongside DLSS 2/3. The more the merrier! I mean, I'm never going to be upset that a game has MSAA, TAA, FXAA, DLAA, DLSS, FSR 2.1, XeSS, etc. Maybe I never use some of the options, but maybe someone else cares enough to use a specific setting.
