6Mb of memory taken up by glDrawElements - Madrayken - Oct 14, 2009 01:14 PM
I have call the following function in my code.
This one line makes 6mb of difference to my memory footprint. It doesn't matter where I call it, nor how many times. It always takes 6Mb. This seems curious to me. Reading through the documentation, I can't find anything saying this function automatically creates a copy of your pre-allocated buffers in system memory. Anyone else found this?
FYI, I'm using the following code to find out where my memory is going:
The reason I'm using this is that since the 3.1 update I can't run my app on hardware directly from XCode, thus removing the possibility of using several Instruments. I'm trying to track that down, too...

Which instruments work only when launched from XCode? I've never used XCode to connect Instruments or Shark to my application.

Wow... what a massive numpty I be. It never occurred to me to run Instruments outside of XCode. All this time I've assumed that everything but 'Shark' is an integral part of XCode. That helps a lot. :-)
[Edit] To add to my already impressive idiocy score, I found that this memory chunk issue only exists in the simulator.
