Occasional stutters in compatibility mode on macOS #74523

Open skarline opened 1 year ago

skarline commented 1 year ago

Godot version

4.0-stable

System information

macOS 13.2.1, OpenGL 4.1 Metal 83, Compatibility, Apple M1

Issue description

I'm experiencing very occasional stutters during gameplay on my M1 MacBook Air when running a very simple game in compatibility mode. This issue exclusively occurs when the game window is on my main Retina display and I have an external monitor connected.

The stuttering is also present on the release exports. I already tried disabling V-Sync and playing around with other settings, so I guess this issue might be specificaly related to Metal.

Steps to reproduce

  1. Connect an external monitor
  2. Set any game to compatibility mode
  3. Run the game
  4. Place the window on your main display

Minimal reproduction project

N/A. Just any project in general, though the 2D Platformer demo works well enough to reproduce the issue.

When compiling godot4.0 in Mac M1 Pro environment, I encountered "ld: symbol(s) not found for architecture arm64". Have you ever encountered such a problem

I tested this, it's most likely a problem with the V-Sync and the hardware, as it's not a 60hz screen. results of the tests can be found in this thread here:
