I found that the CPU usage is very high and the whole program slows down dramatically for some programs with frequent and significant screen refreshing operations, such as rotate. I wonder whether running Scratch consumes much CPU or GPU? And is there any way to improve it? Or all I can do is to use a more powerful PC?

For, 2.0, if Stage3D is enabled, it'll off-load work to the GPU. If not, it's software as far as I know. For 1.4, it's all software. For 3.0, I think they're trying to offload to the GPU via WebGL but I'm not up to date on that.

now they just need to offload javascript by rewriting it in Rust

WASM FTW!

Scratch programs vary in run speed on different machines.
This is something that is important to keep in mind if u make projects/game which game timing relies on game tics.
If u make your game on a fast computer the game can be much harder or easier on a slower computer.

My computer has a 17:37 5k time? Is it fast?
