What Scout says:
Context3D.drawTriangles (flash.display3D) 47ms 90%
My scene is taken from Away3D Examples, where perelith knights are animated on a chessboard. Ive even reduced their number to 25 and i get ~15 fps on Nexus7 (2012) tablet (debug=false build).
This surprises me because there is a video
http://www.youtube.com/watch?v=nkHNfETPkmE#t=85
where a guy has over 110 animated meshes on the scene, a weaker device and gets ~40 fps.
He is using his own Stage3D engine tho..
Is that Away3D slow, or Context3D.drawTriangles, or me doing something wrong?

EDIT: same scene with knights, no shadows, fps~45.
I still wonder why so simple scene runs so slowly.

Hes not using real time lighting. Shadows are faked / planes.

Disable both the light and shadows.

Thanks! That helped!
I guess shadows / light should be prebaked into models
