Hi,

i'am programming game with a few scenes etc.

To remove sprites i'm using function removeObject.

The problem is when i try to play with iPhone simulator and instrumets after going to other scene everything is autoreleased /removed. That's OK. after a few minutes playing 'created and still living' in instruments are circa cca 10 kB. that's OK.

BUT........

when i try to play with iOS , real device and instruments, every second 'created and still living' in instruments are increasing. after playing a few minutes it's 5 MB !!!! memory. and still increasing.

What can be a problem ? :(

P.S.: after playing on the iPhone about 5 minutes the game fps decreasing :(

Ignore your simulator results. Remember, its a SIMULATOR, not an EMULATOR. It doesn't operate the same way at all and is completely useless for judging any performance-related issues.

If you suspect a leak, try using the leaks instrument. More insidious leaks can get missed by this instrument, but most of them will get caught (and even some that aren't actually leaks).

Don't use the "allocations" instrument for tracking allocations- use only the "VM Tracker" instrument, which includes virtual memory. The only important number there is the amount of "dirty" memory.

That said, 5 MB of memory is really not a lot, and I really don't see much of an upward slope in the device screen you linked.
