I am having a bit of a performance issue here… Can anyone help me understand what Profiler.CollectGlobalStats is ??? Refer to the Image :-
If I’m not mistaken, that’s time taken by the profiler itself. You should ignore that; it won’t be there in the built game.
Thanks Mate 
Any Tips for Camera.Render issue , it grew more…
thanks again
Well, twist it open and see where the time is going.
Rendering is naturally going to be a big chunk of time. You reduce it mainly by reducing draw calls — google for tips on that. The short version is, minimize the number of different materials you’re using, as every material means another draw call.
