Time budgets still exist.
This just let you do things like many layers of baked in multi texturing in places where artists had previously ran into engine constraints.
Honestly, having to "make do" when your budget was full probably took more time trying to find neat hacks.

The pop-in and stuttering with RAGE was pretty bad. They finally dropped this method of virtual texturing in Doom Eternal.

Is this AI?

Its just a casual writing style, written like how you might describe it verbally to imply the list of ill effects goes on and on.
Probably just Aspie, judging by some of their other writing (including their About page). I've seen Aspie writing misidentified as LLM output surprisingly often.
Like Vulcans and Data.
The human who wrote the article here ^^ Not AI.. this is how I compress statements. Funny how shorthand reads as synthetic now.
This is a common rhetorical device for humans named parataxis.

A good portion of the world and Lenna herself have asked that image be retired.
Best replacement I've seen: https://mortenhannemose.github.io/lena/
“Good portion of the world” is probably a handful of people.
Her full quote btw:
“Once upon a time, I was the centerfold of Playboy,” says the former model in the new documentary Losing Lena. “But I retired from modeling a long time ago. It’s time I retired from tech, too.”

I found a contradicting statement where she said that she doesn't mind her picture being used in tech. Maybe even in the wikipedia article you got this quote from. I don't have the time to find it right now but here for example she says she's proud of the picture: https://archive.is/fIRoG
"Lena doesn’t harbor any resentment toward Sawchuk and his imitators for how they appropriated her image; the only note of regret she expressed was that she wasn’t better compensated. In her view, the photograph is an immense accomplishment that just happened to take on a life of its own. “I’m really proud of that picture,” she said."

I agree. I shared the quote above (cited as evidence on Wikipedia) because it’s not at all clear she said she disapproves. combined with your quote I think we have a classic case of being offended on another’s behalf.
Oh, I grossly misinterpreted what you said then
> I think we have a classic case of being offended on another’s behalf.
Definitely!

Well, for instance, it's the official policy of the IEEE to not allow this image in new publications. And they're far from the only journal (or set of journals) that have this policy.
Of course. Most people don’t care and a few vocal ones do.
As in most organizations that would know about it and come into contact with it.
I think my comment is true of the graphics programming/research community.
Given that it's use is banned in most academic journals dealing with imaging/graphics, you'd be wrong.
And as several journals have brought up in the banning, it's not even good at what it purports to be for these use cases. It's a pretty poor quality image to start off with due to being scanned to a digital file with 1970s technology.
At this point the ones defending its continued use are the vocal minority on some weird anti-woke crusade that doesn't even make sense on technical grounds.

You’re using vocal minority framing right now. When I care about it, I’m a weird crusader for caring and noticing. But then you organize a campaign to change it.
There is a large body of literature using these images so it’s helpful to have a comparison which is persistent through time and familiar.

Critical thinking caps required for this one.

I was repeating your framing.

Now at least parts of it are paged out...
Who is Lenna?

A copyrighted image of a nude model elected for no obvious reason has a test image in the University of South California by some pervs and then used in a lot of papers as a test image.
Or, a standard cropped image of a playgirl used in the field of image processing.

"elected for no obvious reason" isn't quite right, as a test image for computer graphics it has regions of very high frequency detail and regions of very low frequency detail which make it easier to spot various compression artifacts, and it makes a good study for edge detection, with both very clear edges along the outline, but more subjective edges in the feathering.
It's redish. Ok it has a blur and details on the foreground but could have been any image with blurred background and a face.
"very low frequency detail", we are talking about a 512x512 picture here, it has low and high frequency details (FFT speaking) like most photos.
"Good for edges detection" doesn't mean anything. Like, is the image good for edge detection or the algorithm is good at detecting edges ? What does "subjective edges" even mean ? Does it mean hard to spot ?
That looks like technical reasons but it just noise. They literally grab a playboy magazine and decided it was well enough (and indeed, it wasn't that bad, yes). Still not professional. The message is "We have playboy magazines at work and we are proud of it".

Try out running different edge detection algorithms on that image and you will see that there is a lot of disagreement amongst them in the feathering region. Exploring what the differences are, and how the algorithms lead to those differences helps build intuition about the range of things we might call an "edge", and which algorithm is appropriate for a particular task at hand.
It’s perverted now?
It's literally cropped pornography.
Is a nude picture perverted?
No. That is not the question.
The question is "do you hang out with an erotic magazine at work ?" and "Is it normal ?"
No I think the social context is inappropriate. However I do not think possessing or liking such a picture is perverted. I also do not thinking a cropped version of the picture which has no sexual content is inappropriate.
The eponymous woman in the Playboy photograph.
Which image?
No, the primary "cost" was artists having to fill a world with unlimited textures instead of just filling memory and then having to make due.
The constraint of "limited texture memory budget" also puts a constraint on how much work the artists can do. Remove that constraint lets artists do unlimited work. It might sound like a plus because "freedom!" but it turns into a minus trying to actually ship on time and at budget.
I get that wasn't the point of the article's "cost", but thought it was worth mentioning.
