How many web developers understand that a low-end integrated GPU on a laptop can draw full 4k screens of pixels at 3000 frames per second?

Honest question, what if you need clip by path (aka border-radius + overflow: hidden) + 0.9 opacity + box shadow + let's say blur on hover + transition of all of that. Suddenly it's really hard to do even 60fps, or is there a simple way?

It continually amazes me how peoples' brains don't connect these. Okay, web people don't know how to make games, but they surely have at least seen footage of these games and know they run on the same computers. How do they think all those pixels end up on the screen?

Sure, nice. Now please explain, if it's that simple, why skia & webrender are so HUGE projects, done by groups of very talented people. And why isn't there any simple 2D GUI lib for that. All other libs I'm aware of have their tradeoffs.

I think, with the evidence presented above, you should maybe re-evaluate your claim that these groups are "very talented".

Another possibility is that they are actually talented, but the foundation (the web, browsers, etc) is too awful to create high-performance software on.

skia is just 2D canvas lib, it's not browser-related at all - it's also used by sublime text, flutter, sciter, ...
