But we've had an understanding of what frame generation is since day one. People realized it was not 'just witchcraft' because the latency data showed very early on that it remained similar whether running at 60fps native or 120fps* with frame gen and Nvidia Reflex enabled. We've even had laymen on forums understanding that aspect of the tech perfectly, funnily calling it 'fake frames' for ages, because it adds absolutely nothing to real game performance.
If the so-called expert outlet like Digital Foundry did not understand it from day one, that would be more than a little embarrassing. One look at the latency data would've shown exactly what the tech is doing, because DF should know that higher FPS should be intrinsically linked to a lowering of latency. There should not have been a learning curve over time, or an adjustment in their reporting of how frame generation works, because it was readily evident how it worked and just needed a ton of nuance attached to the reporting of it.
The tweet is perfect because if DF are taking issue with calling the tech a 'performance multiplier' now for Wichard's given reasons, why were DF comfortable calling it that multiple times in the first videos (which also just happened to literally parrot the Nvidia marketing line)? All roads lead to incompetence here - either it's incompetence in understanding the tech, incompetence in communicating how things work in their videos, or incompetence in tempering their own hype when describing technology like this as a 'performance multiplier' and a 'game-changer'.
I won't go as far as to accuse them of taking the free luxury cruise tickets from Jensen Huang, but dishonesty is all you're really left with if there wasn't some degree of incompetence involved.
