I recently bought an iPad Mini 4. I've tried quite a few games on it, and am noticing some problems with low frame rates and choppiness during scrolling. Happens in both 2D and 3D games. Some examples: Geometry Wars 3 Evolved (3D twinstick shmup) - seems like it's maybe 30fps. Sword of Xolan (excellent 2D sidescroller) - also seems to drop to 30fps a lot. These same games run very smooth on my iPad Air 2 with iOS 9. Sword of Xolan also runs very smooth on my iPod Touch with iOS 7. Anyone else have a Mini 4, and what is your experience?
