DLSS, Ray Reconstruction, Frame Generation in viewport? See video

Is it possible to have those in viewport ?
I think especially in viewport while working we could use the help when building heavy scenes, since having the overhead of the editor causes lower fps as opposed to a finished executable.
It would great if we could have like double the fps, even if that FPS and up-resized resolution would not be quite “real”. Sometimes while working it matters more to have a fluid viewport.

Would that require a plugin from Nvidia ? Couldn’t Epic handle those ? so we can have a solution for each update.

If you don’t see the benefit of in-viewport frame generation and dlss, here’s a video which showcases exactly this.
It shows how it can help with the navigation and workflow making the fps more than double.

They don’t have nanite and the vray or chaos vantage technology is very different I imagine, probably way more heavy, but the video is exactly what the title is: how to use DLSS and frame generation to speed up the navigation.
