Hi everyone, I’m experiencing extreme memory usage in Cursor, leading to constant crashes. The main Cursor process + Cursor Helper (Renderer) combined are using over 7GB of RAM, which seems way too high for a code editor (see attached screenshot). Issue Details: Cursor’s memory usage keeps increa…

Hey, does this happen with other projects as well? It might be related to having too many conversations in your chat history. Try opening a new project. The issue might also be connected to having Shadow Workspace enabled, try disabling it. If none of the above solves the problem, try clearing the c…

I’ve been through this same path, with an 8.4+GB ram consumption. Seems a bit extreme to have to reinstall, and then the solution is not permanent you can get back to this undesirable state again :frowning:

I’m on Windows 10. I’ve found the Cursor folder with a cache folder among many other folders and a few files. Are you saying I need to delete everything in this folder? For me, it’s under “C:\Users\warre\AppData\Roaming\Cursor”

Great find. thanks for helping!
