   Hi,

   just a quick post to share with you a quick test that I did with Starling :
   http://www.kouma.fr/lab/StarlingStressTest/

   You can choose the number of MovieClips, and to animate some properties like xy, scale, alpha and rotation.

   The results seem pretty good to me. Note that I didn't do any specific optimisations, just normal code, it's just plain Starling.

   You can grab the sources here (maybe you will need to add the Starling lib, minimal components by bit-101 and my Stats class) :

   Enjoy

   Around 600 sprites with 60 fps on my windows machine.

   Which is not much actually...
   Also have to consider this post http://saqoo.sh/a/en/2332

   Yes it's not so much, but it's more than I expected I made this test to see what Starling is capable of. I think Starling is at the beginning, and there is a room for future improvements.

   BTW, I looked at Saquoosha's exemple, I think maybe it could be optimised a little (see my comment).

   I'd like to make the same test with the classic display list... maybe if I have some time.

   Thanks for creating this extensive benchmark!! Awesome =)

   Of course, there is room for improvement, especially when the same object is reused multiple times -- but I think for most real world scenarios, Starling is already very very useful & fast! =)

   More optimizations will be done, of course, in the upcoming versions.

   My machine is rather powerful(i7 radeon6950 8 GB ram)and i get 51 fps even with 1 sprite on the screen.( But first time it drops below 51 is when i reach 2000 sprites)
   Looks like with ~30 sprites it works better on my macbook air:P

   I did some tests with other demos:

   http://dl.dropbox.com/u/7009356/StarlingTests/bin-release/Startup.html
   57-60 fps (60 but every few seconds it drops to 57)

   http://dl.dropbox.com/u/7009356/StarlingTests/physics2/bin-release/Startup.html
   40fps at the start then 57-60 when nothing is moving

   http://dl.dropbox.com/u/7009356/StarlingTests/Starling-Tests3/Startup.html
   55-59 fps

   This is great.
   Seems like alpha, scale, movement or rotation have no effect on performance.

   I also created some of my own tests when Starling came out comparing it to traditional bitmap blitting and the ND2D framework

   I am very interested in finding out how to make Starling run faster. I initially wanted to start off with ND2D and then Starling got released
   The API is there and all the good work paid off for the usability part. Now the authors need to build some good shaders and memory managers. Even if they looked at ND2D I think they'd find something good to add to Starling framework.

   Thanks for posting the results, guys! As I said, further performance optimizations are of course looked at, promised! =)

    Hello, first post in this forum.

    I tested this with my machine and managed to get about 2400 sprites animating nearly 60fps with all the effects on (alpha, rotation, scaling etc.). I think that's pretty amazing thing to see on Flash Player compared to older versions using traditional Flash display list. 2D with Stage3D is way to go for performance hungry animations.

    Overall CPU usage was around 15%. My rig has Nvidia GTS450 / 4.6ghz Intel 2600K / Windows 7 64bit.
