Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
When I launch Cursor, it uses too much CPU and my laptop cooling running loud.
I remember that this issue was reported as Powershell related by someone else. But it wasn’t solved so I want to report it again.
The most interesting thing here that I can restart TS server and it’ll reduce the background CPU load significantly.
16% of CPU usage may seem like not a loot but it’s on i7 155h with 16 cores and 22 threads, the more threads the less percentage will be shown, and it definitely impacts cooling system and temperatures.
Steps to Reproduce
Just run Cursor and open JS or TS file to make language server run as well.
Expected Behavior
Low CPU usage when idle as it should be
Screenshots / Screen Recordings
This screenshot shows CPU usage when Cursor was ran without TS server restart.
The second screenshot shows reduced CPU usage after TS server restart.
So, I just ran Cursor, opened command palette and activated “TypeScript: Restart TS Server” and CPU utilization reduced significantly.
On both screenshots I didn’t do anything, just was looking into Task Manager to see CPU utilization when I do nothing to editor or opened files.
The TypeScript abilities remained untouched after restart so I can’t understand why I have more load at the beginning and less load after the restart.
It would be good workaround to set up auto restart for TS server on each launch but can’t do that. Maybe Cursor team can.)

Does this stop you from using Cursor
No - Cursor works, but with this issue
