High CPU and GPU Usage Causing System Freezes While Using Cursor AI

[azizsobirjonov (Sobirjonov Azizjon)]

I am writing to report a critical performance issue I am experiencing while using Cursor AI 1.2.4 on my computer.

While running the application, my system consistently shows extremely high resource usage—specifically:

• CPU usage spikes to nearly 100%
• GPU usage reaches 100% (Intel UHD Graphics)
• Memory usage exceeds 87% of my 16 GB RAM

This causes my entire system to slow down significantly, often leading to freezing or crashing. I have attached a screenshot from Task Manager for reference.

I kindly request that your technical team investigate this issue, as it severely affects the usability of your application. Please let me know if you need any additional system details or logs to assist with your investigation.

Hey! Can you share a screenshot of your cpu processes in the task manager? I was able to help someone solve a similar issue a few days ago and would like to confirm its the same issue.

Thanks for sharing! Could it be related to this github issue from a few years ago? ( rg process taking up all my CPU · Issue #98594 · microsoft/vscode · GitHub )

Try the fix by setting “search.followSymlinks”: false" in your IDE settings.

Report back here on whether or not this works so others with your issue can see the fix! Good luck!

edit:

never mind, it looked liked this worked, but it does not.

original:
I can confirm that this works for me, GPU issue is solved.

This is a vscode setting, not a cursor setting.

thank you @2jfs904judsw20600jik !

I guess you’re using the integrated terminal and it outputs lot of lines, like stack traces.

You should use an external one, or open another terminal tab over it.

Remember Cursor is a web app runing in a browser (electron). For the terminal it uses xterm which is drawing the terminal on a canvas using GPU. It’s as fast as it can be, but still slow and GPU hungry. If you’re using a laptop with shared dissipator, it then enable thermal throtling on the CPU.

I created an issue on xterm, please upvote and share it :
