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.
