Reviewers and the leaker in this article is rightly ignoring frame generation. FRAME GENERATION IS NOT PERFORMANCE. It is a smoothing technique. it is meant to be used when you already have a high framerate (>60FPS) to get to your monitor's refresh rate. So using multi framegen to get from 30FPS to 120FPS will feel like you are playing over a laggy internet connection. (yes I'm that old. the internet used to be very slow.)
So to be clear, the technology has its uses but at this time, counting it as performance is misleading or even downright lying.
When Nvidia starts to make those frames responsive and actually usefull for things other than smoothing out the framerate and making people feel good about that tiny number in the top right corner of the screen, then maybe we can start looking at it as performance.
