All these questions need much more powerful GPUs than current top-of-the-line. And game makers know that better graphics often sells the game.
Better graphics sells games, no doubt. But there is also a tradeoff between investing huge amounts of resources into developing/optimizing for what is a tiny ultra-high-end niche that can afford the bleeding edge hardware.
The OP is not disputing this - all he is saying that this stuff is not what drives the GPU market since years ago anymore.
No, the same way he didn't try 200K / 1000fps. It's not really needed.
Even if some people are so extravagant as to got to having it, they're not enough to drive the sales of such cards at the moment, in fact few even have an 8K display or TV, so the combined expense for card and monitor makes it a non-starter anyway.
Which is why the vast majority of those cards goes to ML people.
However, it’s fun as hell
Or is this more like hi-fi zealotry?
