Stage3D performance issues on the various mobile devices

Hello ~

I have developed game project with air mobile. (forgive my bad English)

We used stage3d to develop 2D ActionGame. Although it's based on 2D, we used lots of sprite and effect, so it needs to high spec mobile device.

Recently we tested the game on the Android Mobile device. Target devices are Galaxy Edge(QHD), Xperia(new model), Galaxy 4, Optimus(old model), Galaxy Node4(QHD).. etc...

We keep the game resolution and stretch the screen to fit each mobile devices.

The problem is, the old mobile device works fine... showing good frames and has no frame drop.

But newest mobile device(especially high resolution mobile devices), worked bad... showing low frame rates, frequent frame drop, and high temperature. (some time, the device shut down...)

I guess, although we scaled game to fit the device supported high resolution, It seems to has very high cost to rasterize the game scene.

I try to change the resolution of stage but not work good..

Someone told me the information that unity3d keeps game resolution and resolution of the mobile devices do not affect the game resolutions.

Is there any solution to work out? or Does Adobe have any plan to support multi device resolutions for Mobile Projects.
