!gaming is a community for gaming noobs through gaming aficionados. Unlike !games, we don’t take ourselves quite as serious. Shitposts and memes are welcome.
Our Rules:
1. Keep it civil.
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only.
2. No sexism, racism, homophobia, transphobia or any other flavor of bigotry.
I should not need to explain this one.

Beyond that, go for it. Not everyone is on every site all the time.

It's almost like having double frame buffers for 720p or larger, 16 bit PCM audio, memory safe(ish) languages, streaming video, security sandboxes, rendering fully textured 3d objects with a million polygons in real time, etc. are all things that take up cpu and ram.
I didn’t realize web browsing in Chrome required fully textured 3D objects. Not to mention playing 720p video with PCM audio in a separate app doesn’t grind everything to a halt.
well the gpu doesn't care if it's 2d or 3d, but you are rendering a whole bunch of textured triangles.... (separated into tiles for fast partial or multithreaded re-rendering), and also just-in-time rasterizing fonts, running a complex constraint solver to lay out the ui, parsing 3 completely separate languages, communicating using multiple complex network protocols, doing a whole bunch interprocess communication in order to sandbox stuff
Everything, including Chrome, is rendered as a 3D object these days. It's a lot faster, but takes more RAM.
There are shared libraries that have to be loaded regardless of you having a tab that uses them or not.
That’s not how dynamically loading libraries work. They load and unload as needed.
I will run any game at 60fps if it was designed for this exact machine that does nothing but play games designed for it and is also 16-bit with pixel graphics and also has low quality audio and also fits in the memory of the cartridge
Are you talking about games? There, it's mostly textures.
Web, that's a whole other story, why it uses so much RAM.
WebGL means the browser has access to the GPU. Also, the whole desktop tends to be rendered as a 3D space these days. It makes things like scaling and blur effects easier, among other benefits.
Good to know, thanks.
