Performance of the iPad 1 versus the original Galaxy Tab

In a graphically intensive part of my app I am getting 18 frames per second on the Galaxy Tab while on the iPad I am only getting 4 frames per second. Both are set to use GPU mode. iOS resolution setting is set to high. Both are set to full screen. Both are using air 2.6.

Is there anything I can do?

I've found out 2 things.

I had 256x256 textures scaled to 512x512 inside of a movie clip. This was very inefficient on iOS. When I had my texture scaled to the native size inside of my movie clip and the scaled the movie clip itself I got a huge increase in performance (about 9 fps extra).

Tweening the alpha property causes frame rate issues on iOS. One or two tweens is ok but I had 8 movie clips w/ tweens on 64x64 scaled images and that brought my frame rate down about 5 fps.

I'm still suprised that my "inferior" android device performs better than the iPad even with these optimizations. However the iPod touch 4th gen is faster than either by a good margin.

Remember to use all PNG.

This is especially important for iOS devices becase other formats require additional rendering on the cpu.

Does it matter if I use lossy compression on my images?

Normally things go very slowly on iPad when you exceed the dimensions allowed for textures. The changes between AIR 2.6 and 2.7 on Android weren't so dramatic, but they were on iOS, so I'm guessing that when Android runs into the same problem it's able to deal with it faster under 2.6 than iOS under 2.6. It would be interesting to see how those demanding parts work with AIR 2.7 on iPad.

Hi,

Could you test the application with AIR 2.7? There have been significant improvements in AIR 2.7 in cpu mode.
