As someone who grew up when you could physically count the bloody pixels on the screen, this whining about a miserable invisible miniscule artifact makes me palmface very hard.

Also as a person that grew up when game consoles could connect to the TV via an RF Switch, the image-damaging effects of Temporal Anti Alias smearing are extremely visible, and NOT a "miserable invisible miniscule artifact." They're massive on the screen. The particular examples shown in this video do not show it particularly well because it only focuses on raytracing, but the effects of TAA are still visible because turning on raytracing almost always forces on TAA, since the low resolution raytracing benefits from the smearing TAA causes.

I focus on the playability and addictiveness of the game; you focus on the immersiveness and photo-realism of the experience.
That does not make either of us right or wrong, we're just weighing different aspects differently.

Gamers massively overstate minor inconveniences. TAA smearing, upscaling artifacts, VA ghosting and blooming, ray tracing noise, all of that you get used to it on a day or two and never notice it again but leave it to the gamer to go on a crusade like their lives and the world are doomed because of it

Someone mentioned Neural Radiance Caching to me recently, which Nvidia's been working on for a while. They presented about it at an event in 2023 (disclaimer: account-gated and I haven't watched - but a 6-minute "teaser" is available: YouTube).
I don't really understand how it works after having skimmed through some stuff about it, but it sounds like it could be one of several ways to improve this specific problem?
It's at least used in RTX Global Illumination as far as the nvidia site mentions it, and I heard rumors about Cyberpunk getting it, but unsure if it's used in current tech or not. I think I heard mentions of it in some graphics review of a game.
Yeah I'm also confused about its current state / status in currently-released games. It looks like a significant enough of a feature that I would naively assume that if it was implemented in a currently-released game that the devs would boast about it, so I guess it's not there yet?
