In this case this look something Away specific . @John: I ran, just to test the power of pure Molehill , a scene with 224 spheres all moving ,scaling and rotating simultaneously .Yes this is not 500 sprites.But each sphere was 1984 triangles. My fps was around 40-50 at my desktop and 30 steady at my very very weak notebook.
