Hi, I have an application that crops, translate and rotate a image based on user gestures, then blend it with another image and renders it on a GLKView. It was very fast on iOS 8, but when I compiled it with iOS 9, it became much slower.


Does anyone is having problems with Core Image and iOS 9? Can I fix it by migrating to Metal?


Thanks

Our app uses GLKViews with CoreImage and the performance has gone from snappy on iOS8 to unusable on iOS9. Initial tests with a metal view have not been encouraging, as there seems to be a performance hit from the CIFilters.
