I have no doubt you would have tested it. Also, which of those two devices you linked to do you recommend for the purpose of testing G-Sync?
As for the VRR range, I've been thinking about G-Sync's V-Sync solution for a while now. I may be out of my depth here, but while it effectively acts like standalone V-Sync above or below the G-Sync range, is it identical, or does it have differences from plain old V-Sync? That is, is it actually G-Sync acting like V-Sync when needed, or is it just falling back on V-Sync when required?
I know one of the only difference between V-sync off and G-Sync, is that G-Sync starts the scan directly from the top of the screen, so if G-Sync + V-Sync off is exposing the presumed 1ms polling rate's inability to complete near the bottom of the screen within a certain range nearer the G-Sync ceiling, I'm assuming the only way G-Sync + V-Sync on prevents this is by somehow buffering the remaining frames near the bottom (even possible?). So, in very crude terms, could V-Sync in this range be considered a "buffer" to G-Sync?
Urg, I really wish Nvidia had technical documentation on G-Sync available (not that I could fully understand it anyway).
