GPU vs CPU render mode Adobe AIR

问题

I had the following question: BitmapData lock and unlock not working on android

Now, encountering that issue, reading about render mode, I'm very confused how a script that simple fails in GPU mode,but is very fast on CPU mode.

So the question is, how GPU mode works and how CPU mode works for adobe air? And why on GPU most of the stuff works better, but not that script

Note: Base bitmap size should be bigger than 1400x1400

回答1:

There are some limitations on GPU render mode.

Adobe recommends direct render mode. See following lines from Adobe help,

Note: In order to leverage GPU acceleration of Flash content with AIR for mobile platforms, Adobe recommends that you use renderMode="direct" (that is, Stage3D) rather than renderMode="gpu".
