Linking to an 81 page document isn’t helpful. What specifically in there are you referring to?
No it doesn’t. It allows you to run a game at a higher resolution for no reason at all
Other than the reasons like I said - running it at higher settings while maintaining a playable framerate. The point is you don’t have to lower settings as much with DLSS.
You fundamentally don’t understand what it is and what it allows you to do.
Nvidia can say what they want, but reviewers didn’t follow those.
Sounds like you need to find better GPU review sites.
