Hi, this is my first post.

I have recently move from Windows to Mac for developing iPhone games.

Now i have my first question:
Is there a good free/cheap tool for measuring the performances in my games?
In windows i used nVidia PerHUD
http://developer.nvidia.com/object/nvperfhud_home.html

Is there something similar for Mac?

thanks a lot.

Welcome!

Xcode comes with OpenGL Profiler for OpenGL performance analysis, and Shark for CPU performance analysis. They should do the job for you. After installing Xcode, you can find them in the /Developer/Applications/Graphics Tools and /Developer/Applications/Performance Tools directories, respectively.

Good luck!

Hey, that was quick!

I will take a look on them. Thanks a lot.
