Pretty simple setup, some shapes, some materials, some lights. Nothing special.

Framerate as a swf the browser: 50fps
Framerate in adobe air desktop application : 36fps

I would have thought that the desktop version would be faster. Any know tweaks?

Use the AwayStats object and make sure your AIR app is using Hardware acceleration.

It’s not running in “Software mode” if that is what you mean. The awaystats object just gives me the same framerate: 38/48.

So using AIR instead of the browser plugin is just slower. Good to know.

Im working on Away3D 4.1 Beta. Just wanted to check how my project will perform exported to AIR. And like 3dNewb wrote with AIR desktop You loose a lot fps.
Even on empty stage3D (just view, scene, and view.render() in every frame) i have 50/60 FPS. Why ? Nothing to render there. In browser even in softwareMode i have 60/60,
its obvious:P

First i checked application.xml, it looks like this.

<?xml version="1.0" encoding="utf-8"?>
<application >
  <id>TaernAir</id>
  <versionNumber>1.0</versionNumber>
  <filename>TaernAir</filename>
  <name>TaernAir</name>
  <initialWindow>
    <title>TaernAir</title>
    <content>TaernAir.swf</content>
    <systemChrome>standard</systemChrome>
    <transparent>false</transparent>
    <visible>true</visible>
    <minimizable>true</minimizable>
    <maximizable>true</maximizable>
    <resizable>true</resizable>
 <renderMode>direct</renderMode>
 <depthAndStencil>true</depthAndStencil>
  </initialWindow>
  <!-- 
 More options:
 http://livedocs.adobe.com/flex/3/html/File_formats_1.html#1043413
 -->
  <supportedProfiles>desktop</supportedProfiles>
</application> 

(tested also with <renderMode>gpu</renderMode>)

when updated AIR SDK (from 3.5 to 3.7) i gained +5fps, so now its 55/60fps on empty stage (but still not 60!);

I checked GPU usage with GPU-Z.
With AIR - On complicated scene im getting 30fps and almost no GPU use
The same scene (10 animated characters and some 3D objects, lights, 140k POLY) uses a lot of GPU in browser and performs with 60fps.

Looks like air is not using GPU at all.
Is that normal AIR behaviour or i have some configuration issues?
