What filetype were you working on when this happened?

very, very slow in here also... it started suddenly yesterday. Can't remember if there was an update before the issue started.

I'm working with plain js files. Everytime I try auto-complete (command+space), the CPU usage goes +100%

This will likely be solved when vscode upgrades typescript version 3.

Try to roll your own typescript version in vscode.

1. npm install typescript@next
2. go to vscode settings
3. add this line: "typescript.tsdk": "<absolutepath/to/project/node_modules/typescript/lib/>"

4. Reload window

meanwhile try to add this line to vscode settings: "typescript.quickSuggestionsForPaths": false,
