And before integrated GPUs or even discrete low-powered GPUs the User Interface was rendered using the CPU itself (software rendering). This was a long time ago, back in the old days of text interface in CGA and simple 2D sprites. (1980s)

>What information is the CPU sending to the GPU that it can't just send to a display

It's a bit like this image. Very much simplified, you can think of the CPU sending information like this

  • There are 3 vertices (points) at the x, y, z coordinates (340, 239, 485), (312, 285, 512), (352, 297, 482) that form a triangle.
  • The vertices have these and those colors, textures, bump maps, reflective values, opacities etc.
  • The camera looks at them from position (112, 756, 912) with this and that angle, viewport, zoom.
  • There is a spotlight at (567, 88, 45) with this angle, shape, color, intensity. There is another one at (342, 1274, 1056).

And the GPU will come up with

  • What is the RGB color of pixel 1234, 342 on the display.

As others have answered, the CPU could do this, but the CPU is optimized for doing a bit of everything, and the GPU is optimized for doing a lot of floating point (decimal value) calculations in parallel.

There are two major things going on.

First and most weird, many games don't focus on advertising themselves. Instead, they pay online marketing companies to find them customers. Those companies then produce videos, put them on various online services, and try to get people to sign up for the game.

This provides an odd incentive problem. The marketer's goal is to get you to install and play the game long enough to get it to count as a successful customer acquisition. They are not in the business of getting players to stick with the game. Because of that, they may feel free to completely lie about the contents of the game, so long as it gets sales.

The second issue, though, is why some game companies lie about what's in their own games themselves. It turns out that online game marketing is a big numbers game. You show a million ads, 0.01% of people click on the ad, you adjust the ad, 0.02% click on the ad, you just doubled your ad's effectiveness. Wow! Because of this, there are a lot of marketing companies and standard practices out there, and it turns out that making good ads is hard. So, instead, everybody makes the ads that they know work. For example, the "watch somebody pull keys wrong so the lava falls on the treasure" ad format is pretty effective, so everybody started using it, despite what their actual game was about. If you like the game, it doesn't matter that the ad didn't match up, and if you don't like the game, it also doesn't matter. Mobile companies actively discuss the pros and cons of these misleading ad strategies, not as an ethical issue, but just as another strategy in a numbers game: https://www.mobileaction.co/blog/user-acquisition/gardenscapes-ad-strategy/

The actual temperature is still the actual temperature no matter if it is calm/windy or humid/dry.

If the "actual temperature" outside is 1C but a strong wind makes the "feels-like temperature" -5C... then you might get hypothermia faster than you would relative to a calm day, but no water is going to start freezing because the "actual temperature" is still above 0C.

It works the same way with humidity: the actual temperature is still the actual temperature, but humidity levels can make it harder to sweat and cool yourself and so that gets accounted for when they tell you the "feels-like temperature".

"Bonding" is, in most human societies, as a really good thing. We celebrate marriages and friendships all the time. Being dependent on someone else, though, is a bit more troubling, because it implies that you cannot manage on your own, which is bad because it means that you can't end the relationship if it becomes more harmful than beneficial.

But "co-dependency" is a different thing than dependency. The word looks like it should mean "two people who depend on each other," but that's not what it is. A codependent relationship is a relationship that is severely uneven: one party primarily benefits, and one party primarily suffers. Imagine a relationship with a husband who sits at home, drinks, does not clean, does no chores, does not work, does not help with the kid, just sits and watches TV, and a wife who has a job, does all the chores, raises the kids, feeds everyone, etc. That's a codependent relationship, and it's a bad thing (except, of course, for the beneficiary). Some people have what's basically a disorder, in which they will actively look to get themselves into these situations as the caregiver, and they can be described as "codependent" or having a "relationship addiction."

Generally when whale dies it's corps support whole ecosystems, and can take years to decompose. First, large scavengers will feed on it, and those will be on or near the surface, then small bits and pieces will start falling down and support deep ocean ecologies, but we don't truly understand those. Depending on how deep you go, they will feed anything from fish to microbes, and entire deep ocean ecologies rely on decomposing animal bits falling to ocean floor.

Our local Catholic churches have Friday fish fries during Lent. Fish and chips/fries, hushpuppies, maybe cole slaw or potato salad. You don't have to be Catholic to pick up a plate. As Episcopalians we observe Lent also, and some of those churches have great fried fish.
