This video is quite good and answers your question i believeWhat's really confusing me is that in both Nvidia's marketing slides and also the DF preview video, it shows a roughly 2X performance uplift from 40 to 50 series but this is with 2x and 4x FG respectively. Surely this means that ALL of the performance uplift is due to the additional frame generation, meaning there's literally no raw performance uplift at all?
This just doesn't make sense, especially in the case of the 5090 which, based on specs alone, should be about 50% faster than a 4090.
