Hey, this issue might be related to some extensions. Open Process Explorer within Cursor and check what is excessively consuming resources. Also, try launching Cursor with the flag cursor --disable-extensions.
It would be great if you could share the information and screenshots of the processes being used.
I concur, single core overuse stems from electron VScode, the ‘extension host’ runs all installed extensions in a separate process from file watcher and search processes etc. As such, this isolation can end up with 100% single core cpu usage when one specific, single threaded process becomes overwhelmed.
And it occurs mostly in linting but also sneaky background extensions running telemetry, file indexing etc. Extension can conflict or poorly optimized extensions can be culprits.
Sorry there’s no iExtension you can buy €700 on the apple store
