iOS peak memory usage is too high during startup


My game often crashes at startup on iPad 2 due to running out of memory (I can tell by iOS JetsamEvent error logs), but if it manages to successfully start it’s using only 130MB of memory. Unreal’s memory report says that peak usage reaches 410MB which is what’s likely causing startup crashes.

Assets compression is disabled (if it’s enabled, memory peak usage is even higher!).

Could you recommend a way to further investigate and combat it?
