I tested 1000 sprites a second and it works with a decent FPS in release build but still needed to be optimized.But I have started working on the BufferInitializer .That is going to recycle particles.You will only need to specify the buffer length and that is it .Hope it will boost up the performance significantly.I hope after the weekend it will be ready ( as I am busy also with Steering framework for Away3d at this time also). As Ringo said the merge approach is problematic for dynamic stuff like particles.
