I have very annoying stuttering effect in Flash build. It appears as short-time but really heavy framerate drop, happens periodically. Editor and webplayer runs smooth at 400fps.
Probably it is Garbage Collection, but i have done many things to get rid of it and dont see it in Editor using Profiler for now. Actually i am not instantiating anything during gameplay, just using pools for some objects and thats it. Also, not using OnGUI at all, nor GUIText etc. I am using NGUI (it eats huge amount of frame processing time, that scares me, but i dont see spikes).
The question is - how can i profile flash build and find out what happens during this fps drops/pauses?
