macOS stutters in a minimal project
Reproduction steps:
1. Open the attached “Repro“ project
2. Open the “Assets/Scenes/Scene.unity“ Scene
3. Build and Run the project
4. Observe it
Expected result: No stutters are present
Actual result: The sphere stutters
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.

I can’t even take gameplay footage of my game without the stutter or launch my game on mac. Hope this will be fixed soon!

This is a critical issue for me. It's very difficult for me to work on my game, because I'm stuck in 2021.1, trying to work around all of its numerous bugs. Upgrading the project to any of the more modern editor versions introduces unbearable MEGASTUTTER, which looks like dozens of frames dropped every few seconds in both editor and player, for no clear reason.

I don't know if this is the same issue but I'm seeing a noticable stutter when running the editor player on Mac. Running an M3 Pro chip and when profiled the CPU is spiking with 100ms > 200ms spend in RenderLoop (99.1% to 99.6% self). Appear to happen every 5000 to 6000 frames roughly.
I've removed everything from the scene and the issue can still be seen from within the profiler.

I had same issues with my project on M1 Pro machine. For me its blocker to transition from 2021.3 to newer version. Simple character controller with capsule stuttered with no visible reason.
