What're your thoughts about Nvidia DSR?

It works and it is 1:1
What else is there to say.
However it just is not good for Desktop usage because the Focus % u apply will throw-off where you might need to click certain things.

Nvidia DSR wasn't designed with desktop use in mind I don't think. I prefer using custom resolution settings to apply 1440p resolution to my games instead of DSR, as I don't have to fret about a smoothness filter, because at a lower smoothness, I notice moire patterns, and at a higher smoothness, the overall image is blurry. I've tried using custom resolutions to achieve 4k, but it's just not possible for some reason (it bugs out). So to reach 4K resolution, I use Nvidia's DSR and either 33-50 percent smoothness.
That said, at 4K, Most text in the Steam in-game overlay, as well as some crucial elements (such as the console in Valve's games) are far too small to read, so I typically settle for setting a custom resolution in the Nvidia Control Panel, usually at 1440p, and then using either 2-4xMSAA with MFAA on, as text and the like are still legible.

10-20% smoothness is best really. Anything over around 33% = Blurry picture.
Smoothness needed is more of a question of how clear your screen already appears to you. Obviously a little play is needed with the DSR focus point % to get it where u want. But if u already have a quality display with good pixel pitch, then u should already have a sharp picture to start.

The focus % u choose also will throw off your pointer accuracy (it's clicking/zero point) of where this lands when using DSR to upscale your Windows Desktop.

What I usually do is leave my Windows Desktop at the Display's Native Res; then have DSR only enabled for 1.78% (1440p) and 4.0% (2160p) and then set the focus % to around 20. A low focus % (how blurred everything is, to compensate for smaller, unevenly sharp pixels, due to scaling) is already enough to throw off the point for Windows Desktop, so I prefer to not use it for that. But with these DSR options enabled, now the games have this option for screen resolution. To make it fit proper, ensure the game runs at full screen. As you won't be able to have Desktop set to 1080p, and have the game run at higher res, while under Windowed Mode of any kind. So full screen mode would be needed here. Games look supurb however given how the up-scaling works on 1080p screen through DSR.

But again, for demanding games, 1440p or 2160p will be quite demanding to say the least.
Witcher 3 for example on maxed out settings has no trouble running at solid 60 FPS @ 1080p (with NVIDIA HairWorks disabled) but same settings under 1440p and you're looking at 45 FPS. Then jump to 2160p and you're looking at 15-25 FPS... just an example here.

I find it to just be a gimmick.
Rendering 4K frames, then downsampling them to 1080? What's the point? It looks slightly better? It would look even better if you just used a 4k screen to begin with. Not everyone can afford to run out and buy a 4k monitor? If you can afford the GPU(s) to render 4k frames at a decent rate, you can afford a 4k monitor.
If anything, DSR is just really an advertisement for how much better your games would look on a 4k monitor.

Well yes, that is kind of the point of it being there.

It helps in that regard, so one could see "How will this run if I were to use 4K screen with 2160p native res" for example. Or you could use it for Desktop Res on 1080p screen to gain more desktop real-estate. As 2160p = 4x 1080p screens.

Well, DSR can have issues with some games. These issues usually come in the form of tiny UI but can sometimes end up with graphical glitches.

Although, it's mostly some older games that can have issues.

This.

The only useful aspects I see in it are:
- You can get an idea of how your system performs at 4K before actually going out to spend money on a 4K screen.
- You can take 4K screenshots without having a 4K monitor. If you're into that kind of thing.

Other than that, you're getting a huge performance hit while still looking at a 1080p image. It might look a bit smoother, but I'd rather use 1080p with good AA.
