The performance improvements claims are a bit shady as they compare the old FG technique which only creates one frame for every legit frame, with the next gen FG which can generate up to 3.

All Nvidia performance plots I’ve seen mention this at the bottom, making comparison very favorable to the 5000 series GPU supposedly.
