Hello everyone,
My game (currently in development) runs at 60fps on the iPhone simulator and a 1st gen iPhone. However when I compile and run it as an iPad App it runs at 12fps in the simulator.
Is anyone else seeing this, It's not particularly complex, but why the massive frame drop when I target iPad.
I'm using Cocos2d v0.9.0-beta2
Thanks for any help!
I realize this is an old thread, but I'm seeing awful simulator performance too.
Adding a TMX map (desert.tmx from the Tiled example) with no other sprites and no Chipmunk runs at 30fps max on a 1 year old iMac.
Using Shark, 78% of the processing time is spent in OpenGL rendering, so I'm guessing there is something wonky.
I'm seeing the same thing (really slow iPad Simulator). Browsing through the Apple Developer Forums, it seems that many others are having issues with slow performance as well, so it looks like it's a bug with the Simulator.
iPhone has 153600 pixels to draw, iPad has 786432, that's 5 times more pixels to draw. Unless your game is capable of running at 300fps on the iPhone simulator, then it's not gonna run at full 60 on the iPad simulator.
PS: I know that it doesn't really work like that, but my point is that you've got WAY more stuff to be rendered, and at the end of the day, it's a SIMULATOR... Unfortunately most computers probably aren't gonna be able to run the simulator at full device speed.

Same thing here. I'm very new with iPad (of course) and cocos-2d. But I've seen in simulator this:
cocos2d: GL_VENDOR: Apple Computer, Inc.
cocos2d: GL_RENDERER: Apple Software Renderer
cocos2d: GL_VERSION: OpenGL ES-CM 1.1 APPLE
Apple SOFTWARE renderer?.. shouldn't be it accelerated by hardware?

I've got the same problem with the Simulator. Running at 13-15 FPS, whereas on the iPhone it was 60fps.
It ran fast as an iPhone app on the iPad simulator (i.e. 2x mode), but once i turned my project into a stand-alone iPad app, that's when it went bad.
So, those of us in Europe trying to make a game, what do we do? :p

This has been addressed in several other threads.
Our Cocos2D iPad game in simulator: 20fps
Our Cocos2D iPad game on iPad: 60fps
I thought we all already knew that the simulator was a piece of junk, I hardly see why anyone is surprised at the latest chapter in this story. You'll have to cope until you can get your hands on a device, just like we here in the US did before release.
As a rule of thumb, I would imagine that anything over 15 fps is probably acceptable. But, that depends a lot on what device you're running the simulator on, and why the app is slow in the first place.
iPhone has 153600 pixels to draw, iPad has 786432, that's 5 times more pixels to draw. Unless your game is capable of running at 300fps on the iPhone simulator, then it's not gonna run at full 60 on the iPad simulator.
A ha ha ha ha, this is funny man, you gave me a good laugh.

I have the same problem. My app running on iphone simulator has 60 fps but 15 fps on ipad simulator. But when I install it as ipad app on my ipad device, it runs with around 45-60 fps.
I have 5 layers as background to simulate a parallax scroller. for each layer, there are 3 background pictures(CCSprite) with width of 1024 pixel at the same time. I keep on releasing old pic and loading new pic as the player move on. (These pics are loaded from a CCSpriteBatchNode which initialized with a PNG file)
I know I have to tune my app to use less pictures and less RAM. But could anyone kindly tell me why performance on ipad simulator is so poor compared with real device?
Thanks!!
