I have upgraded my application to cocos 2.2.2 and I cannot optimize the performance using RGBA4444. I tried editing _format: PixelFormat.RGBA8888 in the CCTexture2D.js file but it still doesn’t work. My app was not able to run on iPhone 6 and earlier devices. A lot of our users are complaining about this issue. Help me please
Help me please 
Hello, we don’t have any iPhone 6 equipment to test. Can you tell us the other equipment models that may have this problem?
Hello,
You don’t need use iPhone 6. I want using feature cc.Texture2D.setDefaultAlphaPixelFormat on version 2.2.2 like version 1.9.3
Please help me
I tested this using oppo r11t android os, and no rendering exceptions appeared.
Relly? I’m call cc.Texture2D.setDefaultAlphaPixelFormat(cc.Texture2D.PixelFormat.RGBA4444);
Then this is error loop forever:
ERROR: TypeError: cc.Texture2D.setDefaultAlphaPixelFormat is not a function. (In ‘cc.Texture2D.setDefaultAlphaPixelFormat(cc.Texture2D.PixelFormat.RGBA4444)’, ‘cc.Texture2D.setDefaultAlphaPixelFormat’ is undefined), location: src/project.dev.js:982:48
