I want to be able to run my game without a locked framerate (currently 60 fps). The only way that I have found to run the animation is with a NSTimer. Is there a way to have an unrestricted framerate in Cocoa. If so, a link or a code snippet would help greatly.
If you really want to do this, you might need to use the CGL interface. In a valid GL context, CGLGetCurrentContext
returns an (opaque) context object. CGLSetParameter
can be used to set a value for the kCGLCPSwapInterval
parameter. A value of (0)
disables waiting for vsync.
This enabled me to get around ~700 frames per second on my MacBook Pro
It is not permanent either, perfect for testing/benchmarking.
The Quartz debugger in Xcode 11 (version 4.2) moved this to:
Tools->Quartz Debug Settings->Enable Vertical Sync
