Maybe I'm prejudiced to React and its variants, because I have never used a React app I liked, just React apps that are useful despite their shortcomings.

(It makes me nuts but) I seriously think the web is basically the greatest. And we have some pretty good tools for doing pretty good, that we can use, if we try hard. But also, the whole middle-tier data-architecture is made up by almost everyone, with little guidance; there's incredibly little guidance & views of how we effectively get data to the client and cache & update it effectively.

The tools and tech exist, but instead of clear industrial practices everyone's stringing shit together.

Your user or customer wants their problem solved or their desirable experience delivered. They often don’t care if there are bugs or jank or slowness as long as they get what they want.

Minor issues are usually tolerable, especially when there aren't any alternatives. That doesn't mean there's no cost.

Customers would rather play a buggy/janky game like the Elder Scrolls series, Minecraft (especially early in its lifespan, not really so much anymore), or Ark (the dinosaur game) than play a polished bug-free game with boring gameplay.

Or as another example, customers would rather deal with the ugly UI and slow UI performance of Autodesk Fusion than use a more polished/native feeling application that isn’t as powerful for design work.

It's always possible but not always easy. Some frameworks can and do choose to make certain kinds of errors hard to make, even at the cost of asking more from the programmer. It's a fallacy to think that they're all the same.

I've used other sites that are fully React based that run quite well and don't have these issues. So I can't imagine it is specifically the frameworks fault.

But I do find if developers use these big frameworks and don't use them properly, the slowdowns can be much more pronounced.

It's not a frequent occurrence, unless I have too many games installed, but then those are the downloaded games updating stuff, not Steam. Uninstall the ones you're not going to play in a while if that's becoming a problem.

Steam redownloads the client when it shuts down "dirty" to fix itself, but to me it was happening basically every time.

It just seems to be on my PC. It's only on the store. Even download speeds seem okay. But regardless of whether I use the client, Brave, Chrome, Firefox, Edge, they all are slow for the store page. Even things like the community pages and workshop all load fine. It makes zero sense to me why things like pictures/videos in their store load insanely slow for me, yet the images in things like the workshop have zero problem.

I've been trying to figure out what is wrong for quite some time and haven't figured out what could be causing it.

Steam -> Settings -> Download -> Region
