Hello everyone,

Could you please let me know whether the Draw calls affect performance? In my physics-based game draw calls in cpu utilization is showing above 23%, but physics simulation is below even 1%. Hence I think draw calls have greater impact on performance.

If so, can anybody please suggest me some tips to optimize it so that it can show better performance on iPhone??

Regards,

Asit

I too would like to know about that... In a not very technical way if it's possible <img src="smileys/smiley9.gif" border="0" align="middle" />

What are these Draw calls and why, most of the time, they utilize way more CPU resources than everything else on the game?

I've searched on the net but I see things that are related to 3D engines like Unity.
