iPod Touch x iPhone 3G performance

#1 The 3G is actually just a surprisingly slow device. I don't know about 3.1.2's impact, but you should expect the touch to run faster.

BTW, which Touch? 2G? 3G?

#2 The 2nd generation iPod touch is quite a bit faster than the 3G iPhone, but if anything, the latest OS should be more efficient. Each new iDevice always improves at least a bit over the previous one, so they never match exactly :)

#3 Hi.

My iPod is 2G model MB528LL.

I think the problem is because my game is 100% script, so I'm porting several routines to C++, do you think this can resolve the performance problem?

Or torque has problem running on iPhone 3G?

Thanks

#4 Yes, C++ will make it faster. There are also minor things you can do to speed it up. There is one problem in a sleep function, for example. Check the source file iPhoneTime.mm, line 91+. Uncomment the commented usleep() call there. More little tweaks exist - we could use a collective thread of fixes if we don't get a new release soon :)

EDIT: iPhoneTime, not Memory. Bah.

#5 :) Thanks

If you have more tips please let me know :)

Thanks
Eros

#6 Hi Man, My iPhoneMemory doesn't have "usleep" the unique file with this function is iPhoneTime and iPhoneMain.


Thanks

#7 Hi all.

I´m printing the time to execute some process on engine, and the problem is in

void DemoGame::mainLoop()
{	
 ...
  Game->processEvents();
 ...
}

The game is spending 200 Ms to execute this command. On iPod Touch the game execute it on 40 Ms

How to I can evaluate my script source to check where is the problem
I´m trying to use getRealTime before and after some functions but it doesn't work, on call after the function the getRealTime is returning "".
I need to know how to get the time (ms) to execute some functions. Do you have idea how i can do it?

Thanks
Eros

#8 You'll probably have to port whatever bottlenecks are in script to C++. Script is much, much slower than C++. So port the sections of code that get called often.

#9 OK I see this everywhere, write that part in C++, ok how? Is there some explanation of how this is done? I don't just replace my script with C++ do I?

#10 Pretty much, yes :)

You can do a 1:1 translation of any loops/number crunching to ConsoleMethods, then call that from script. For a decent example of using the ConsoleMethod macro to create a C++ function exported as a script function, see the movie playback example posted in this subforum.

#11 Thanks!
