If it gives a 50% increase in performance there will be plenty of people who care about, including myself.
DLSS essentially works by upscailing(But a custom upscaler that uses a neural network inferencing algorithm trained specifically for each application to give quick & accurate information to "fill the gaps" with) an image to 150% of the render resolution, so a 4K image renders at 1440p, a 1440p image at 960p & a 1080p image at 720p. Generally GPUs don't take a completely linear hit from resolution changes but it can be very close to linear once you push the envelope, so presumably to get 50% or near you'll be running at 4K with a higher end card, I'm not sure whether anything has used it for below 4K though.

Normal Port Royal run.
https://www.3dmark.com/pr/34656
Port Royal run with DLSS off then on.
https://www.3dmark.com/nd/29145
2 x RTX Titans @2000/4100
6950X @4.46
418.81 Drivers
Interestingly both RTX and DLSS work fine in SLI on Port Royal, if only there were some games that could do it.
As to image quality it is very difficult to tell the difference in Port Royal when DLSS is off and on. It is a big improvement on the Final Fantasy bench where it is obvious when DLSS is being used.

It's not just the benchmark is it...
Why be so negative about a technology that could give free performance increases.
I for one hope it works really well and will be happy to reap the benefits.

It's an upscaling technique, so how on earth you arrived at the conclusion it makes games look better, I'm really to sure.
I don't know if you'd see much image quality difference if you ran this test at 4K res but at 1440P it's a very noticeable difference. Everything is a lot sharper and cleaner. The fuzzy edges on things like that "galax" sign are gone.
It would be great if it works that well on games and not just a benchmark.

See below.
Correct. DLSS can also be used as a sharper more accurate AA solution to TAA and thus give better image quality than native 4K with TAA in some games. There are already videos out there showing this.

I don't think a lossy medium like video is an adequate tool for measuring the difference. I guess I should buy the benchmark and try it out myself, maybe even share lossless screenshots.
Not video itself, people analysing/reviewing the pixels by zooming in.

Not a good way of doing it.
The game needs to be running to get the whole picture, to see how a number of frames merge together at good fps.
A good example of this is the Port Royal bench itself, if you run it on a single card even a very fast one the image at 40fps looks a bit pixelly, if it is run in SLI at 80fps the pixelly image becomes much smoother.

That's simply because it's running at better fps. Which means less repeated frames and therefore a smoother image is shown due to the fact there's less ghosting from old frames. Nothing to do with SLI. Just a result of better frame rate

Nothing to do with repeated frames and SLI here is just a tool to get the fps high enough to make it run properly.

I'm not sure what you mean. I refer to a video where a person views 4K TAA and 1440p DLSS and notes that distant detail is much more pronounced. Of course higher frame rates helps TAA as convergence happens quicker but this is not a solution.

It does. If you had the same power with a single card, it would have the same result. SLI is literally just another means of getting there. It would have the same smoothness.
