Apologies if this has been hashed over, but I'm trying to figure out why performance on a Moto Droid is problematic. Specifically when I have a large background image (1024 x 1024) I lose 20% of my performance. My overall texture memory usage is < 8MB on average, but I'm unsure what a reasonable target is for specific devices.
Is there an easy way to figure out what is causing problems (a profiler/perf analyzer)?
Specifically I go from about 20fps with the background to 30fps without the background. Finding that out took a LOT of manual work just removing individual display objects.
I'm unsure if this is specific to the Droid or if it's just that I have a general performance issue that is masked when running on the simulator (which is always 30fps) or on my Acer Iconia (always 30fps).
