Performance issues for iOS with high resolution.

Question

I made an app with a resolution of 480x320 for iOS. It works quite well.

I then remade it with a resolution of 960x640. In AIR for iOS settings I set Resolution to "High".

The app looked great, however there was a noticeable drop in performance.

The app functioned the same way as the original lower resolution app. but it was lagging.

Has anyone else had this problem?

Am I doing something wrong?

With my game, I had around 60fps on the 3GS, and around 50 on the iPhone 4, with the high settings. I got around 10 fps extra by using: stage.quality = StageQuality.LOW;

Air 2.6. I tried with Air 2.7, but it seems like that command can't be used there (?)

I'm no expert, but the bigger the image size, I think the slower it's going to be. I'm designing at ipad size, so I'm having to keep it simple.

I publish for both versions (ipad & iphone).

When I accidentally published just for iphone once it came out small and was really fast on the ipad. Small animations always move quicker!

If you want to design for both, it's best to work in ipad res, so you can optimize..
