How to disable vsync on macOS

Question

With all my SDL/OpenGL programs, the framerate is stuck at 60fps, so looks like the vsync is enable, but not by me, nor in my code or my settings. so i would like to now if there is a way to disable it, maybe in some deep macOS settings?

Answer 1

This enabled me to get around ~700 frames per second on my MacBook Pro.

• Download Graphics Tools for Xcode - Late August 2014
• Install or just mount Graphic Tools
• Open Quartz Debug
• Go to Tools -> Show Beam Sync Tools
• Select Disable Beam Synchronization

It is not permanent either, perfect for testing/benchmarking.

Answer 2

Welcome to SO. I outlined an approach here for a similar question. You should consider that most Mac LCDs are locked to 60Hz, and more recent hardware is limited to 120Hz. Disabling vsync may simply result in wasted CPU/GPU cycles, and possibly introduce tearing artifacts.
