What issue are you seeing?
I see high GPU usage while using the Codex app, and it looks like it is caused by the tiny animation, which does not deserve such an amount of energy consumption.
What steps can reproduce the bug?
- Open any GPU monitoring tool. For example,
macmon, since it allows 250 ms updates. I'm using my own tool since it allows 100 ms updates. - Open the app and ask anything. It starts "thinking," consuming much more GPU power than expected. It's about 70% utilization and up to 1.5 W power on my M4 Pro.
- Hide this spinner. You have two options: you can toggle the sidebar or collapse the chats group.
Codex will still be thinking, but GPU consumption will drop to a low level, with spikes on UI updates.
- Reveal the spinner again (toggle the sidebar or uncollapse the chats group). You will see how the GPU level returns to high.
You can clearly distinguish all three steps in the screenshot. The red line is GPU frequency, and the red area is GPU utilization.
What is the expected behavior?
The application should not consume this much GPU power for such simple tasks. This is significant, since even Civilization VI with a 60 FPS cap consumes less than 1 W of power during the first turns.
