contentScaleFactor

- (CGFloat) contentScaleFactor

device

- (id<MTLDevice>) device

layerSizeDidUpdate

- (BOOL) layerSizeDidUpdate

nativeScaleFactor

- (CGFloat) nativeScaleFactor

When scaleToNative = true, instead of setting self.contentScaleFactor, you should change this setting.

It's expressed in fractions of the nativeScale.

For example on an iPad Mini 3 the native factor is 2.0; thus if you set nativeScaleFactor = 1; then contentScaleFactor = 2.0 If you set nativeScaleFactor = 0.5; we'll set contentScaleFactor = 1.0

presentationTime

- (CFTimeInterval) presentationTime

readwritenonatomicassign

The value of presentationTime will be passed to MTLCommandBuffer::presentDrawable atTime:presentationTime When negative, it means to present immediately (Ogre will call presentDrawable overload) This value is very important if you want to render at e.g.

30 fps: Calling CADisplayLink.frameInterval = 2 is not enough; as the CPU timer will be fired once every two VSync intervals, but if the GPU completes its job too soon, it will present immediately (i.e. in the next 16ms instead of waiting 33ms). In that case you'll want to set presentationTime = displayLink.timestamp+(1.0/fps) See https://developer.apple.com/library/prerelease/content/documentation/3DDrawing/Conceptual/MTLBestPracticesGuide/FrameRate.html

scaleToNative

- (bool) scaleToNative

readwritenonatomicassign

When true (default), we will try to set the contentScaleFactor to the native's.

You can use 'nativeScaleFactor' for further control. Note: Changing contentScaleFactor directly will force this value to false.
