Well, i can see the difference very obviously. I prefer native. “Low FPS” in terms of Framegeneration is basically everything below 40, as this is the minimum FPS Nvidia recommends for Frame Generation. And that is really the Nvidia recommendation, you see the strange behavior even before that.
But i guess not everyone is able to see it, even if its very obvious.
And the Video is the same for any application, MSFS doenst magically exclude all the issus FrameGeneration brings.
