I have a game made in cocos2d for iPhone, I’ve adapted for iPad and works well if not retina.
When I run my game in the retina iPad simulator, the game is very slow, the images of the characters take a lot to load.
Why does this happen? Is the problem the simulator? Am I missing a line of code to run normal?
The code is exactly the iPhone and iPhone is great.
The simulator can have a very different performance profile than a device—in this case your computer’s graphics card might just be struggling to handle the large graphics context of the retina iPad screen. You should always do your performance testing on an actual device, particularly with apps like yours that make use of OpenGL.
