My comment isn't denigrating frame generation, which can be useful.

It's pointing out the absurdity of calling "45fps plus 1-for-1 frame generation" as if it is in any sense "90fps". It's not, and you aren't hitting a 90Hz refresh rate target at any more with it than you were without it. In point of fact, it lowers real FPS because it consumes resources that would have otherwise been available for the render pipeline.

I wish reviewers in particular would stop saying e.g. "120fps with DLSS FG enabled" and instead call out the original render rate. It makes the discourse very confusing.
