heres the same set up but using Metal API

Don’t use OpenGLCore on Mac, Metal is the way to go, and it’s actually a very good API.
OpenGL is not supported by Apple anymore.

The reason why OpenGLCore must be used instead of Metal may be due to the following issues.

Performance deteriorates when creating a new project in Unity 2020.3.23f1 or later.

I happened to have stopped the version at 2020.3.22f1 for about 6 months, but it occurred about a week ago when I upgraded the Unity version. I am at a loss as to the cause. Here is a new project created with Unity 2020.3.22f1 and the play button is pressed. [image] [image] However, when I do the same with Unity 2020.3.23f1, the following happens. Note the graph in the profiler. [image] This phenomenon also occurred in 2021.3.3f1. The above is a new project, so we are able to main…

In other words, Unity’s implementation of Metal is flawed and has not been able to break away from OpenGLCore.
I have filed a bug report for the glitches mentioned in the above thread, and I hope Unity will address them.

Also, I am aware that OpenGLCore is deprecated on Mac/iOS, but I am aware that it is something that continues to be supported.
