Is High Usage of GPU by Cursor while 1 Agent works Normal?

[Victor-Jnr (Ujjwal Kumar)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

While I am using agentic mode Cursor uses about 75% of my GPU. Note this happens only while the agent is working, is this normal for cursor to behave this way?

Steps to Reproduce

Just running the model in an agentic mode leads to HIGH GPU usage.

For AI issues: which model did you use?

Happens with alomost all of them have not tried the MAX models yet but in all others it is the same problem

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey @Victor-Jnr !

Is it normal? I don’t think so.

Can you take a look at this post and see if you’re affected by one of these issues?

Editor freezes, app not responsive when editing a file

Hey, thanks for the report. Editor freezing during editing in version 2.2.20 on macOS is a known issue tied to one specific setting. Cause: If you have this in your settings.json: "workbench.editor.showTabs": "single" It directly causes freezing during any AI file editing. Fix: Open Cmd+, (Settings) Search: workbench.editor.showTabs Change from ”single" to ”multiple" (or delete the line) Reload This should fix it completely. If it still freezes: Clear chat history: ~/Library/Application…

In particular, what is workbench.editor.showTabs set to in your environment? Does disabling hardware acceleration help?

[Victor-Jnr (Ujjwal Kumar)]

The workbench.editor.showTabs is set to multiple in my environment,

I have added disable-hardware-acceleration:True to my Runtime arguments as well, but even after these changes I get the results as in screenshot attached.

As mentioned before, the High GPU load does not cause freezing of cursor i.e. cursor works without problems, but yes it does hugely affect the performance of my device and even sometimes causes screen tearing due to high GPU load.
I have also attached screenshots of my settings for reference:

Hi Colin,

Yes, there’s no longer any high GPU usage. Disabling hardware acceleration appears to have resolved the issue. Cursor now uses no GPU at all during agentic mode.
Thanks for your help.
