Hi,
There is a way to detect what is the device used ? Like 3GS, 4, 4S, etc ?
After many tests, the iPhone 4 is really more powerfull than the 3GS.
If we have blocks like "Running on 3GS", we can use differents stuff to optimise performances.
For exemple, with my 3GS, I can create simultaneous 10 particules (with create), on the iPad 2, I can create 50 of the same particules without performance problems.
I think if it's possible, this can be really cool.
