I haven't, like most people I guess it'll be at least half a decade until I upgrade to a 40 series card. > What is more shocking to me is how low they got the latency on it Most games are perfectly playable at a stable 30fps (33.3ms latency at least). The frame generation is hopefully giving you 90-120fps. So you're getting latency sub 16.6ms, equivalent to stable 45-60fps. That will usually only be noticeable in drawing apps or twitchy FPS games. Maybe they're doing some other tricks like decoupling input latency from frame latency, I haven't looked into it. It's common to do this with physics, in the opposite direction (e.g. run physics at a fixed 33.3ms interval while generating frames as fast as possible, aiming for 60fps).
