i think the prisma vscode extension causes my vscode to go to 200% CPU usage for a very long time. problem goes away if i disable it. i don't have any other wacky extensions installed.

What’s the Prisma vscode extension version you are running?

3.14.0

Maybe you are running into this issue https://github.com/prisma/language-tools/issues/1118 Could you try disabling the file watcher functionality as mentioned in the issue?
