iPhone Simulator performance

Post  ColorDelta on Thu Mar 26, 2009 6:04 am

Hi,

Apologies if this has been covered before (I'm yet another newbie) but I was wondering what kind of performance you guys are getting in the iPhone Simulator?

In Tutorial 06_01/02, I'm getting 29-56 fps, which I'm guessing is to be expected in a scene with that many physics objects. However when I pan from side to side movement is somewhat jerky (fast-slower-fast-slower). Is this normal? I don't have an iPhone / iPod to test on yet but I just wanted to check with you guys if this is a known issue.

I ought to mention that Quartz Extreme and hardware acceleration are enabled and Unity runs very smoothly, but I'm not 100% sure OpenGL ES is switched on in the iPhone Simulator as it's greyed out in the performance monitor menu. Is there a way to check this?

Thanks! Smile

I think things would be smooth if you multiply them with the delta time(sio2->_SIO2camera->d_time i think). Delta time is the time it takes to render the scene one time(1 frame). If you multiply speed with delta time you should move the same distance every second no matter what the frame rate is.

Hopes this helps a bit even thou it wasn't exactly what you was asking for

There was a brief conversation about this in this thread http://forum.sio2interactive.com/about-the-sdk-f1/can-t-debug-and-run-tutorial06-on-device-bad_err_access-t434.htm

Have you changed from Debug to Release in the build options? That made a HUGE difference in render speed for me.

isn't that for the device only? This guy doesn't even have an iPhone

SDK version I have will _let_ me do Debug/Release for both the device and the simulator - there was a small amount of performance increase in the simulator... but you're right, it mostly affected the device.

That's what I get for not properly reading the whole thread!
