What I'm trying to achieve is quite simple: I want to draw a
fullscreen image (RGB_565). On top of it, I'd like to draw a
fullscreen image with an alpha channel. My problem is that I get
terrible performance, around 30 fps. Is there any way to speed things
up? I use a HTC Hero, shouldn't the
This sounds about right. On a device like the G1 or HTC Magic (which
are more or less equivalent to the HTC Hero) it takes about 4 ms to
draw a full screen opaque image. In your case you are drawing two
images and the second one is twice as big *and* requires blending,
which is done in software.
