given GFN is running the same software as you'd run locally (the game), and using the same local hardware (keyboard, mouse, etc) to send the inputs, and then the same local hardware to display the server rendered output (your monitor/TV)... how can be true that GFN doesn't add at least the same input latency as running it locally?

unless there's some trick I'm missing it's going to be at least the same (plus the network latency)

I said same as native console, not the same as the equivalent hardware on PC. If you look at the chart it's comparing different hardware not the same hardware.

The "trick" here is that native devices already have some amount of latency, just they are in an acceptable range for most people. However nvidia can optimize PC hardware to reduce the device's latency such that even with the network latency added it's still faster than the average person's native device. Hope that makes sense.

Something is a little weird with the numbers as shown. 120hz to 60hz only gains 18ms on PC, but it gains 45ms on xbox. Presumably with the same peripherals, tv, network connection, etc. Not really sure what's going on there.

I'm not entirely sure either but I just go with what Digital Foundry tells me https://www.youtube.com/watch?v=jOcFSlniGrw&t=676s

Watch the video yourself.

I suspect it's an unfair test

they should be comparing the same input/output hardware with the xbox

then only switching out the xbox for a PC connected to the same inputs/output

what would be terrible: comparing xbox plugged into TV+controller with geforce now running on a PC with keyboard+mouse+PC monitor

the numbers don't make sense otherwise

I'm getting the feeling that you want a test of the internet connection or something like that by your standard of what a fair test is. I don't think that's what they're going for, but a more holistic "typical usecase" test. That said I haven't bothered to check the video for exactly how the test is setup maybe someone will comment with that info.
