Thank you for reporting this performance issue. We are planning to fix this by implementing CAMetalDisplayLink in the macOS Editor. Since this requires quite big changes in the Editor across different areas and teams, we need to plan this as a feature. Currently the plan is to address it in 2026 Q3. Therefore, we will close this case as a feature request. While we can't guarantee timelines, your feedback is important and helps us prioritize enhancements. If you have additional context or use cases, please share them.

We will investigate fixing this issue in a later Unity version and reconsider backporting it to 6.5 once a fix lands.

Reproduction steps:
1. Open the attached “Repro“ project
2. Open the “Assets/Scenes/Scene.unity“ Scene
3. Enter play mode and observe it
4. Build and Run the project
5. Observe it

Expected result: No stutters are present in both editor and standalone application
Actual result: The sphere stutters in both editor and standalone application

Reproducible with: 2021.3.45f1, 2022.3.51f1, 6000.0.24f1

Reproducible on: M2 Max 15.0 (User’s platform), M1 Max MacOS 14.6.1, Windows 10
Not reproducible on: No other environment tested

Notes:

The reproduction depends on the specific setup. The user has noted that stuttering was more prominent on the 2021 Macbook Pro M1 Max than his 2023 Macbook Pro M2 Max. On the built-in retina display, I was unable to see any stuttering, but the user mentioned otherwise, meanwhile, on external monitors the stutter was very clear.
The user mentioned that in 2023.1.20f1 the stutter did not occur, but I found it reproducible.
This issue is about Mac Editor only. For the Mac Standalone Player see
