MASSIVE memory allocation, or am I reading this wrong?

Hi,

I have an AR app that’s hitting a ‘hard limit’ of 1.5Gb on my iPad and being forced to quit. I’m trying to figure out where all the memory is going, so I built and ran the MemTool2 app, and this is what it showed.

My question is, does this mean it’s trying to allocate over 3 GB ???

How do I figure out what’s causing the massive memory allocation?

Thank you,
