simple changing of mesh position is surprisingly slow?!

Software: Away3D 4.x

Hi
I made a simple performance test with 1000 textured balls (5940 triangles each). Everything went smooth and fine(~24fps) until i tried to animate their positions. Simple moving 1000 spheres up and down brought fps to 8.
This is very counterintuitive, because I’m not doing anything costly like modifying geometry in any way, I just change “Mesh.y”.

To make sure I recreated test in Flare3D and as expected there is almost no difference between rendering static or dynamic balls.

I prefere Away though because of it’s openess and access to sources. So please look further into this strange performance problem.

Greetings.

Sorry, it turned out that I tested a Debug configuration, in Release there is no much difference between static and dynamic versions.

I feel ashamed wink
