Saw that nVidia released this feature in a driver update recently and its apparently similar to AMD's FSR, but I don't understand exactly how either of these are different from the feature in many newer games allowing you to set an "internal resolution" that the game renders at and then displays at higher (likely native) resolution. Googling found plenty of articles comparing NIR to DLSS to FSR, but not to in-game engine options.

We’re currently investigating an issue related to the forum theme and styling that is impacting page layout and visual formatting. The problem has been identified, and we are actively working on a resolution. There is no impact to user data or functionality, this is strictly a front-end display issue. We’ll post an update once the fix has been deployed. Thanks for your patience while we get this sorted.
Nvidia Image Scaling vs In-game resolution scale

Preface by saying I had to look this up a bit, had an idea in the back of my head from reading stuff around but nothing exact. I'll get the ball rolling anyway. Anyone who sees anything wrong please correct me or expand, as always.

From the article.
I believe that FSR/NIS upscale from a lower resolution while applying antialiasing (AA) to smooth any jaggies while also improving the look of textures so they don't look lower resolution. Whereas lowering the render resolution in the game menu ends up with worse looking textures when you upscale it, even if you can apply sharpening filters to smooth any aliasing at the edges.
DLSS is the best solution but only works on Nvidia RTX cards and takes advantage of AI somehow. The other two are different methods of achieving the same thing, that can work on cards without Tensor cores (The AI bit).
So as I understand it for image quality
DLSS>NIS/FSR>In game upscaling+sharpening.
Not sure which is better out of NIS or FSR yet, and of course there are quality/performance levels for each solution that affect the image and frame rate as well.
Resolution Scaling: The Secret to Playable "4K Gaming"
Resolution scaling is a great option if you're looking to eke out an additional 10-15% performance, after tweaking settings. If you're playing at a high resolution like...
