Is 3G slower?

We are experiencing some weird lag in our games only on the iPhone 3G. Even the 2G is working really nice and smooth.

Has anyone else had the same experience? By doing a google search there seems to be some issues with the 3G phone?!

Specifically just the 3G? Are you seeing similar problems with the 3GS?

Only 3G. Seems that performance is a little weaker than the other phones. 3GS and 2G works great without lag.

Maybe the OS version for 3G (3.0)?

What are you using for timing? NSTimer or a thread? If you're using a thread, Apple engineers suggest you avoid using CFAbsoluteTimeGetCurrent() for timing, and instead use CACurrentMediaTime(). This is because CFAbsoluteTimeGetCurrent is sync'd with the network, while CACurrentMediaTime is not.

Actually, I recommend you get on to the developer forums on Apple's iphone development site and search around. There are some really good threads on the differences between the different devices, and Apple engineers will pop up from time to time to give advice (this is where I heard not to use CFAbsoluteTimeGetCurrent, for example).

Yup, it is indeed much slower. I made a similar thread a while back...

Here's a link to an article:

yes the 2G is much faster - we noticed that too.
The 2G sometimes even seems better than 3GS.

iPhone 3G runs at 412Mhz while iTouch 2G is under-clocked to 533Mhz...
