Yes, but that's only going to be available in 2 games to start with - Valorant and The Finals. (I guess your chatgpt query didn't pick up on that).
I don't have a recent enough card at the moment to feel what frame-gen is actually like in those situations, going from 30 -> 60+ fps, but if it doesn't actually smooth out gameplay and only adds an additional float-y feeling to the controls, then it doesn't sound good unless you're playing something slower paced.
Also this seems to explain the "PC Latency" that Digital Foundry was banging on about...
Reduces latency based on the game’s latest mouse input.

How to set it up, if you have the equipment:
Gettings started, tips, tricks, and frequently asked questions to help you get the most out of the NVIDIA Reflex Analyzer

Then this breaks it down:
Optimize end to end system latency using NVIDIA Reflex technologies, PC changes, peripheral tweaks, and more.

So it seems like the game should be running at around 60fps ( if you look at the example where it shows latency where they're looking at the cups, and turning on DLSS halves the latency and the FPS go from 27-28 to 70~ and the latency drops to 35ms ).
I'm not entirely sure why DFs system is so slow compared to the example Nvidia showed off (maybe they were using different readings meaning they're not entirely comparable), but it's still a fairly large increase in terms of percentage (7ms would roughly be a 20% on Nvidias 35ms figure, if the Nvidia example is only using the render latency).
