When did we just give up on, you know... actually rendering the frames that the game generates? Faking resolutions, making up frames that never existed, that doesn't sound like magical new tech. It makes it sound like you can't figure out how to make better hardware so you are trying to hide the fact with trickery.
When the additional hardware investments failed to return quality and there was a more promising way forward.
First of all, please try to remember that all GPUs create fakes.
There is nothing real about shaded and bumped triangles, very few things in a real or fantasy world are built from them.
It's just an approach that Nvidia, and most others, chose from many other imagined and tested approaches to render those worlds on screen. And it's been improved and carried forward for decades now, but it's still very fake and far from even photorealistic.
Its biggest issue is that increasing resolution and realism is hitting hard limits. 8k content means 4x the effort of 4k and ever more elaborate world data still needs to be broken into triangles to be bumped and shaded.
Nvidia has hinted that it is on a mission to completely transform how screen content is produced into something that is more akin to AIs painting from a scene description than a GPU rendering from a brushed up mathematical approximation generated by designers and game engines.
And they are replacing one type of fake with another, which offers much better looking results for less design and computational effort.
Yes, it's trickery. But I can basically hear those Intel Larrabee guys wailing at how inferior that shady bumpy triangle trickery you regard as the only digital truth was to their true ray tracing!
But both just cannot deliver the visual quality AI generated illusions promise, so Nvidia is extremely forward looking and has every right to shake, extend or even replace a trickery they largely built in the first place!
