We have an OpenGL-based iOS app. We use a CADisplayLink to control our drawing updates.
I just got the new 10.5" iPad Pro and we are getting a maximum frame rate of 60 rather than the 120 we can theoretically get on the new hardware.
We set up the display link like this:
NSLog(@"Maximum FPS = %ld", [UIScreen mainScreen].maximumFramesPerSecond);
self.caDisplayLink = [CADisplayLink displayLinkWithTarget:self selector:@selector(displayLinkCalled:)];
caDisplayLink.preferredFramesPerSecond = 120;
[caDisplayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];The displayLinkCalled: method is called 60 times per second. The log statement does indicate the UIScreen's maximum frame rate is 120 FPS.
Is there anything else I need to do to update at higher than 60 FPS?
